For communication encryption, the app uses technologies based on the public key infrastructure and symmetric cryptography.
- Asymmetric encryption using 2048-bit-key digital certificates
- RSA-type digital certificates
- Possibility of implementing proprietary cryptographic algorithms
- HASH-type SHA 256 algorithms
Voice encryption
Uses the recipient's digital certificate.
The digital certificate and the corresponding cryptographic keys are stored on smartcards.
The session key is generated per call, using the smartcard.
AES encryption with 256 bit keys CTR mode.
Message encryption
Uses the recipient's digital certificate.
The digital certificate and the corresponding cryptographic keys are stored on secure element.
The session key is generated per message, using the smartcard.
AES encryption with 256 bit keys.
