The phone encryptor is a desktop telephone encryptor that provides complete end-to-end secure voice communication between CRYTEL users over the PSTN. phone encryptor allows clear calls and can be switched to secure mode, when required, by pressing the security mode button on the phone encryptor. Once the secure link handshake is completed, conversation with the other party is digitally encrypted while maintaining excellent voice quality. The phone encryptor automatically establishes a unique encryption key for each secure call by a Deffie-Hellman key exchange mechanism. Coupled with 256-bit AES encryption algorithm, the phone encryptor assures the highest level of cryptographic protection to the User. |
