Cryptech technology
MANAG presents the latest encrypted mobile phone CRYPTECH technology, the ultimate solution to protect all GSM voice and SMS communications. Available on new and most attractive devices, the technology benefits from a new audio engine that ensures complete absence of echo and provides the best voice quality, comparable to that of a traditional phone call. Security is assured by the best public encryption algorithm, ASE256, with symmetric 256 bit keys.
Cryptech encrypted mobile phones do not require technical skills or complex settings. Encryption keys are easy to configure directly by the user, thus ensuring total privacy. The AES256 algorithm, with symmetrical keys, ensures the best protection against any kind of wiretapping or phone tapping/eavesdropping.
The crypto phone Cryptech, top level product derived from military and government requirements, provides two ways to generate the anti spy encryption key to be used during the conversation: the 4096 bits Diffie-Hellman protocol (as well as Elliptic Curves Diffie Hellman, according to user preference) provides a session key which is subsequently merged with the symmetric key set on the device by the user, producing a different encryption key for each call. Users can employ different combinations of Diffie-Hellman and shared keys. For example, Diffie-Hellman key can be used without prior sharing of a common key, thus enabling phone calls between encrypted cellphones which do not share common encryption keys. When Diffie-Hellman is employed (both alone and in combination with symmetric shared user keys), the final key will be automatically deleted at the end of each the call. User keys can be stored in a secure repository, which is protected by a password. Such keys are displayed on the screen in hash format, thus ensuring both secrecy in case of device theft and the possibility of comparing two keys on different devices for compatibility.
The simplified version of the secure GSM software, named Easy Cryptech, offers the same level of security as its advanced brother Cryptech but fewer complex options, so as to bring encrypted phone calls to the masses. Being a sort of “plug-and-play” anti spy ciphered mobile phone, Easy Cryptech can be employed by inexperienced users because there’s no need to configure user keys or mess with advanced settings. A quick key exchange algorithm (ECDH, Elliptic Curves Diffie-Hellman) is employed to automatically generate the cipher key without user intervention on the crypto phone, destroying such key upon call completion. The strong AES256 algorithm is employed for voice and SMS encryption, offering the best security level while in a user friendly application.
The secret of the whole technology our secure GSM mobile is that of being simple to use and yet utterly powerful. After an initial automatic protocol phase which performs key agreement and synchronization, the encrypted phone turns voice into data, encrypts it and splits it into small packets. Such data packets get transmitted in real-time through the GSM data channel reaching the other device. Upon receiving the secure packets, the other device performs data decryption, assembles the original audio and plays it on the usual phone speaker of the device. In turn, each crypto phone device performs audio encryption and decryption in real time, so as to let the user experience a full-duplex encrypted voice communication, comparable to a normal phone call conversation.
SMS messages are encrypted with AES 256 algorithm as well, with cipher keys chosen by users or automatically generated during a secure GSM voice call. Long encrypted anti spy SMS text messages are supported, enabling users to write ciphered SMS messages containing thousand of characters. A recently added function is the clear SMS text secure storage: users can choose to receive traditional SMS message and store them in an encrypted secure archive on the Cryptech or Easy Cryptech secure phone.
Recently, a remote command function has been added to the Cryptech and Easy Cryptech software. Users are given the possibility to execute remote instructions on their secure mobile phones, such as wiping or cellphone GPS localization, only from allowed phone number and by means of a secure secret password. The true potential of the whole system is that all the remote control messages are encrypted SMS text messages, impossible to decrypt and shielded against phone tapping or eavesdropping. In case of phone theft or lost, the owner can remotely wipe the whole content of the crypto phone and storage card, as well as locate the cellphone position. Coordinates can be shown on a map on the screen of another Cryptech or Easy Cryptech device which has been formerly allowed by the owner of the lost or stolen device. Remote mobile GPS location requires GPS compatible devices.
