This paper proposed a new Secure Parallel
Cipher Block Chaining (SPCBC) mode of operation that provides enhanced security over the current modes.
7814-W implements the Electronic Codebook and the
Cipher Block Chaining modes of operation for both encryption and decryption, and supports key sizes 128 bit, 192 bit, and 256 bit.
The new mode of multiple encryption is the triple-DES external feedback
cipher block chaining with output feedback masking.
For some methods, such as DES operating in the Electronic Code Book (ECB) mode or DES in the
Cipher Block Chaining (CBC) mode, the consequences of lost cells are small on data, voice and video communications (for these modes, one additional cell at most is affected for a lost cell).
Security features include IEEE 802.1 li-compliant radio with AES-CCMP (Advanced Encryption Standard-Counter Mode with
Cipher Block Chaining Message Authentication Code Protocol) and TKIP (Temporal Key Integrity Protocol); a complete suite of 802.1x EAP (Extensible Authentication Protocols), including EAP-TLS (Transport Layer Security), EAP-TTLS (Tunneled Transport Layer Security), PEAP (Open standard from Cisco Systems, Microsoft and RSA Security), LEAP (Lightweight Extensible Authentication Protocol); end-to-end TLS/SSL 3.0 (Secure Sockets Layer) and SSH (Secure Shell) tunneling; and end-to-end AES (Advanced Encryption Standard) 128-bit encrypted tunneling.
