CTR mode is special in a few ways: (1) Padding doesn't apply. Normally, a block encryption algorithm (AES, Blowfish, DES, RC2, etc.) emit encrypted output that is a multiple of the block size (16 bytes for AES as an example). With CTR mode, the number of bytes output is exactly...
CTR mode encryption uses AES (advanced encryption standard). The protocol is designed for WLAN (wireless local area network) multimedia applications. The basic idea is to offloadthecomputationallyintensiveencryptionandauthenticationservicestotheendsystems' CPU. Enhanced methods are employed to implement the ...
