Wireless GSM telephony is expensive with high smartphone prices, long term mobile plans and accruing calling costs. Calls are prone to be recorded and monitored. Voice quality is poor due high compression ratios. Not to forget the contract that is signed containing personal info. Introducing the WiFi Crypto Phone Now there is a choice. A low cost GSM alternative phone. The answer to privacy deficient smartphones. A new method of wireless telephony that is innovative. Confidentiality through voice encryption is a standard feature. It has the stylish looks of a smartphone, the mic/speaker marks of a good old land line phone and is the lightest of mobile phones. Assembled are only essential components. Glass screen and keyboard were not needed. Elegant operation with two buttons on the left for navigating the phone book and another one on the right to call. 8000 Hz 8-bit PCM 64 kbps sampled raw voice data is reduced to 32 kbps via 4-bit ADPCM compression, which accounts for good voice quality. Finally triple DES encryption is applied to have a stream of P2P encrypted voice data packets that are sent through the internet. Contacts and WiFi network credentials are managed with the PC application through USB. Up to 8 networks and 16 contacts can be added. WiFi to coexist with GSM Mobile phones are tending towards WiFi and encryption. Yet these attempts don't really feel right. It's like trying to blend oil with water. Crypto GSM phones for several thousand dollars, smartphones at up to a thousand dollar, VOIP phone adapters with hidden recurring costs... Not so with the Decibit WiFi Crypto Phone. Dealers invest only in the hardware manufacturing cost. It can't go lower than that. Hence customers get to own this crypto phone at lowest price in the market. [Note: Dealer inquiries are welcome. Direct shipping from assembly line in China.] This phone contains a U.S. manufactured Wi-Fi module from Inventek Systems, which utilizes a Broadcom MAC / baseband / radio chipset with FCC, IC and CE compliance certification. Integrated is a secure chip AT90SC1818CT (obtainable only by signing a NDA) that is the core component for key generation and real time voice encryption. Session key is exchanged using 2048 bit RSA asymmetric key encryption. Voice data is encrypted with triple DES and transmitted as CBC stream between WiFi phones. The secure chip is input with both internal raw voice data of 64 kbps and the encrypted data of 32 kbps received from other phone. It compresses and encrypts the raw data and decrypts and decompresses the encrypted data. It then outputs decoded raw 64 kbps data for listening and encrypted 32 kbps data to be sent to other phone. This cycle repeats every 8ms. Overall data rate to/from secure chip is about 100 Mbyte/h. 1000 triple DES operations are performed every second. Cipher Block Chaining is utilized where a cycle counter is being used as IV and also XOR'ed onto the session key. UDP packets carry a bunch of data of 13 cycles for 104ms length to ensure low latency. 2048-bit RSA key generation and storage happens within secure chip. The phone number is derived from this RSA key. Both RSA key and triple DES session key are managed inside the secure chip. All voice encryption and ADPCM compression are performed within the secure chip. No other cryptophone on the market does this. They use the CPU of the mobile phone for cryptographic tasks. A sophisticated lab can easily extract the keys from such unprotected chips. This phone was therefore designed in hardware and software from scratch for it's main function to provide absolute confidential phone conversations by using a specialty secure chip that is built to prevent and withstand any such extraction attempts. Any logged past internet traffic is worthless data and can not be played back a second time, even if one or both of the phones are in possession with the attacker. A two stage RSA encapsulated session key creation, exchange and assembly method assures this: Furthermore, the RSA modulus is not in plain; not due security reasons, but to assure good randomness while deriving the phone number and the UDP socket port number from the RSA key. Active and user friendly support is provided with AES-128 encrypted automatic firmware updates. About WiFi and 3G, 4GWiFi operates on local short range with fastest connection speeds and emitting at low output power thus causing minimal radiation exposure. GSM is exposing the user with increased radiation levels to penetrate walls while connecting with a far located cell tower. It is reported that the World Health Organization considers cell phone radiation as "possibly carcinogenic". 3G connections are already bad for health, where 4G is worse, causing more exposure to radiation due higher data rates. This WiFi phone with 63 mWatt has 97% less output power than a GSM phone with 2000 mWatt output power. 63mW/2000mW = 3%. What does WiFi Telecom mean? Every WiFi Phone, after switching on and connecting to a Wi-Fi network, registers itself with the server at www.WiFi-Tele.com. The server stores the RSA public key and current IP address and thus functions as a dynamic DNS service provider. After initiating a call, a direct UDP link is established between phones to exchange encrypted voice data. Outgoing calls can be initiated from anywhere in the world just by knowing the other phone's number. To receive calls however, the internet modem/router NAT has to be setup for port forwarding, to allow a caller to reach the phone behind the firewall on the local area network. Only calls between WiFi Phones of this brand are possible. Regular phones can not be called. This WiFi Crypto Phone establishes confidential P2P calls. WiFi range extenders can be used to amplify any weak spots. How does it operate? A phonebook entry is selected by two buttons on the left, navigating through up to 16 phone numbers. Each location is sound encoded in Roman numerals. Empty and unchecked entries are skipped. Roman numerals from 1 to 16 are: I, II, III, IV, V, VI, VII, VIII, IX, X, XI, XII, XIII, XIV, XV, XVI Once a contact is chosen, the call can be initiated by the right side single button, which is also used to end the call. Those left side buttons adjust the volume of the speaker during a call. Incoming call is signaled by playing a melody or by vibration, which is configured using the PC application. Coverage is no issue. Plugging in a cheap WiFi repeater to a wall plug ensures good connectivity at all times in a house or office. Ringing time while a melody is playing is 30s. If one phone ends the call, the other phone will almost immediately mute and end, too. If there is connection loss for longer than 20s, the phone will abort the call. LED Indicators Upper red light: No network. Green light: Connected to network. The phone is ready to make or receive a call. Yellow light: Call is in progress. Lower red light: Battery charging status. Specification Battery: 1200mAh Li-Po for 5 days standby and up to 8 hrs talk time Size: 125mm long, 50mm wide, 10.4mm high Volume: 65 cm³ Weight: 69 g (incl. battery) Confidential: Yes Network: Wi-Fi, IEEE 802.11b/g/n, 72 MbpsConclusion In almost all categories, a Decibit WiFi Crypto Phone is an outstanding choice. Be it health related or initial and running costs or legally binding contracts or privacy related issues or the huge value that stands behind the whole project. Donations will help to recover back the expenses made for secure chip purchase, casing mold and production of the product. Expenses are currently at the 50K$ mark, not including any form of salary or equipment cost. It is a great feeling to have an encrypted conversation. It must feel weak to be unable to shake off the parasite on your back breathing down your neck that is violating your privacy. For less than 50$/year it is now possible to own and use a crypto phone of great value and exterminate the term "phone bill" at once.

SDK CONTENT IS ALLOWED ONLY TO BE USED WITH MAMP-OS SMART CARDS. SDK MAY BE DISTRIBUTED ONLY WITH ORIGINAL CONTENT AND REMARK OF ORIGIN. SDK TOOLS AND SOURCE CODE EXAMPLES ARE PROVIDED AS IS AND USER IS RESPONSIBLE ALONE USING THEM. USER IS RESPONSIBLE TO PROVIDE AND USE PROPER EQUIPMENT. UPLOADING OF UNTESTED OR ERRONEOUS CODE MAY RENDER SMART CARD USELESS. SDK CONTENT IS NOT GUARANTEED TO BE ERROR FREE. UPDATES MIGHT CORRECT OR ENCHANCE ANY DETAILS. THERE IS NO COMMITMENT OF GUARANTEE FOR UPDATES. THE AUTHOR OF MAMP-OS HAS ABSOLUTELY NO RESPONSIBILTY AND CAN NOT BE HELD LIABLE TO USER CODE WRITTEN BY 3RD PARTIES OR ANY DAMAGED SMART CARDS OR ANY OTHER DAMAGE CAUSED BY THIS PRODUCT OR USING THIS PRODUCT. [Note: With MAMP-OS V1.2 it's no more possible to destroy the smart card.] Setting up development environment to use example source: Copy AVRASM32.EXE V1.52 into your working directory. Assemble source file (user.asm) by double clicking on user.bat. Upload user eeprom (useree.hex) and user code (user.hex) using MAMP-OS Terminal (mampos.exe). MAMP-OS upload mode requires 3.579 MHz oscillator for 9600 baud. Reset smart card, get MAMP-OS V1.0 ATR and push 'Upload' button. First user eeprom then user code will be uploaded automatically. Adjust baud rate setting within terminal and oscillator of smart card reader if user code is using different settings. Select 19200 baud for the example source. Reset again to see user code ATR. KEEP EXAMPLE SOURCE COMMANDS AS THEY ARE WHILE STARTING UP WITH A NEW PROJECT. This will ensure that MAMP-OS upload mode can be entered again and again without unneccessarily destroying smart cards. MAMP-OS Terminal can be compiled using Borland C++ Builder 3. User Accessable Memories: AT90SC3232C: CODE: $0000-1FFF 16384 bytes, 8192 words (virtual word address) EEPROM: $8000-$9FFF 8192 bytes (virtual byte address) RAM: $0400-$04FF 256 bytes (real byte address) System calls seperate between EEPROM and RAM using most significant bit of address high byte. EEPROM: msb set, RAM: msb clear. System call routines with RAM address as input will always correct address to $04xx. Virtual addresses (EEPROM) will always be masked to the right EEPROM space. Do not use absolute code addressing. RAM is partitioned as follows: $400-$4B7 184 bytes USER RAM $4B8-$4C7 16 bytes aes key $4C8-$4CF 8 bytes [MAMP-OS user code] interface $4D0-$4FF 48 bytes common stack Do not use more than 24 bytes of the stack when using system calls. Byte Format: 1 initial stop bit (while transmit) 1 start bit 8 data bits 1 optional even/odd parity bit 1 stop bit cbr r16,_parity_enable ;8N1 - no parity sbr r16,_parity_enable ;even/odd parity cbr r16,_parity_even_odd ;8E1 - even parity sbr r16,_parity_even_odd ;8O1 - odd parity cbr r16,_convention ;direct convention sbr r16,_convention ;inverse convention sts RAM_byte_format,r16 Data can be transmitted in direct convention (ATR $3B) or in inverse convention (ATR $3F). Defining ATR is completely under user control. Refer to ISO 7816 Part 3. Baud Rate vs. Clock Frequencies: 9600 baud @ 1, 2, 3, 3.579, 4, 4.915, 6 MHz 19200 baud @ 2, 3, 3.579, 4, 4.915, 6 MHz 38400 baud @ 3.579, 4, 4.915 MHz 57600 baud @ 4.915 MHz Please note that 6 MHz is the upper operating limit. Not all smart cards will work with this frequency. If user code is set up with 9600 baud @ 6.000 MHz and that smart card doesn't work with this frequency, e.g. no ATR, then it is always possible to upload new code by using 3.579 MHz oscillator in the smart card reader and selecting 5760 baud in terminal.

KNOWN ISSUES AND LIMITATIONS: Maximum data length is $80 = 128 bytes for all protocols. T=0 protocol LEN = 0 to transmit 256 data bytes from smart card to terminal can't be realized with one system call _sc_tx_T_0. Instead use it twice. T=0 protocol byte transmission error control and handling, which is mandatory, is not implemented. The example source code is sending an appropriate return code instead, if a byte level parity mismatch is detected. Advantage is that card is not locked up and this solution is more near to OSI model. Disadvantage is that remaining bytes to receive are ignored and it's possible to have collision on I/O line. //This may be corrected in source when T=0 protocol system calls are completed. PTS (Protocol Type Selection) and FI, DI values are not used directly but there is variety of choice to select between terminal clock frequency and baud rate. Developer is free to implement any solution within user code. T=0 protocol carries some disadvantages: - Commands must be defined in pairs. A seperate command must be used for each direction of data flow. This is a security hole where memory can't be erased before each new command is received. - For one action (put data / get resulting data) two requests are sent from terminal. - INS may not be odd due to old Vpp based write access handling (historical). - INS may not start with $6x or $9x, because the acknowledge byte would be interpreted as a return code or delay request. - Byte error detection / correction is in 'wrong' level of OSI model. - 3 unsuccessful attempts to receive a correct byte locks up card and reset by terminal is needed. - No complete checksum protection of header or data, instead byte level 1 bit parity protection, which provides minor protection only. The provided T=E protocol does have none of these disadvantages. A parity mismatch, if parity enabled, will cause an early break from receiving all bytes of a request. Therefore it is recommended to use 8N1 with T=E protocol. Here is the structure of implemented T=E protocol: Terminal request: [LEAD] [CMD] [INS] [REF1] [REF2] [LEN] [DATA_IN] [CHK] Smart card answer: [LEAD] [CMD] [INS] [REF1] [REF2] [RCH] [RCL] [LEN] [DATA_OUT] [CHK] LEAD: Leading byte is $80 for MAMP-OS and can be any value for user code. CMD, INS, REF1, REF2, LEN: MAMP-OS implements only CMD = $B0 and INS = $02 for code upload and INS = $03 for eeprom upload. LEN is in range of $04-$14. User code is free to implement any of these values, except that LEN is limited to $80 bytes. RCH, RCL: Return code high and low byte in the answer. CHK: Checksum is XOR of all bytes including LEAD until excluding CHK. Initial value can be set up within user code. MAMP-OS uses $FF.

> WI-FI TELECOM CALLS OUT GSM NETWORK Voice Encrypting Simplistic Wi-Fi Phone Questions Smartphone Concept Ingolstadt, Germany — Oct.13, 2014 — Decibit today introduced the WiFi Phone, a new concept mobile phone allowing confidential P2P voice calls. Decibit's WiFi Phone addresses core issues to benefit users of wireless telephony. These issues include answering to health concerns by low antenna radiation exposure, assurance of privacy by encryption and riddance of mobile plans, calling costs and long term contracts. The World Health Organization states as a fact that the electromagnetic fields produced by mobile phones are classified by the International Agency for Research on Cancer as possibly carcinogenic to humans. RF output power requirement of 2 W to reach far distance GSM cell tower antenna shrinks to mere 63 mW for a local Wi-Fi access point. The design integrating the secure chip AT90SC1818CT for key generation and real time voice encryption, exchanges session keys using 2048 bit RSA in order to encrypt and decrypt voice data streams using triple DES. Glass screen and keyboard are not present as the WiFi Phone combines only essential components for the given task for simple operation. The lightweight device is suited to make worldwide free of charge calls from airports, hotel rooms, as well as from home and office. Decibit Co., Ltd. was founded in 2007 and is registered and has sales & support office in Thailand, with registered business and production in Germany and production partner in China. # # #
