How does Sycret Work? 5

Security Features All encryption and decryption takes place inside the microSD (SDencrypter); Nothing is ever in the open or visible to the Android operating system. Even a Trojan would find nothing. A unique RSA-2048 key pair are generated at first-time login. These private keys are securely protected inside the Sdencrypter. A voice encryption key (AES-256) is randomly generated and is different for each secure call session. Generation takes place inside the SDencrypter. All session keys are encrypted and exchanged peer to peer; the Sycret server never sees them. APP Authentication: A User PIN (numeric password) of 4 to 16 digits is used for authentication to get access to Sycret APP. The SDencrypter will lock after 5 wrong PIN attempts. Your security is portable when you move from to a new device. Time-out protection enforces an automatic logout after a set period of inactivity. Sycret voice microSD (SDencrypter) is FIPS 140-2 Level 3 certified. 6
