- afhof 15y agoThis article seems to gloss over one of the cipher modes of AES called CTR mode. CTR eliminates the interblock dependency while staying more secure than ECB. CTR mode uses a separate counter (such as 0, 1, 2...) that gets factored into the key for each block. Compare this to the CBC which uses the cipher text of the previous encrypted block as part of the key for the next plaintext block. CBC has a data dependency where CTR does not. I would suspect that they can get much higher cipher rates by using CTR mode rather than CBC.
