For the protection of voice calls, instant messages and content, the Encrypted Mobile Content Protocol™ (EMCP) optimizes the delivery of encrypted content in real-time, even across low-bandwidth wireless networks.
Cellcrypt uses standard encryption technologies including:
-
Advanced Encryption Standard (AES) for symmetric encryption
-
384-bit Elliptic Curve Cryptography for Authentication
-
Elliptic Curve Diffie-Hellman (ECDH) for key agreement
-
Secure Hash Algorithm (SHA) for message digest
Cellcrypt’s Dual Cipher system uses double-wrapping for added security. For example, voice calls are first encrypted using RC4 with a 384-bit key and then encrypted again using AES with a 256-bit key.
