Parallelizabilty and prepocessing in Modes of operation (with example)
In another way, ad example in CBC, since the second(and so on) block depend on the previous one, we can't apply this two property.
I saw this question for understand this. … I Invent this mode inspiring by CBC.
In fact, I can't parallelize the encrypt and decryption too (because for the second block I need the first one to compute the XOR (the same for the decryption). …
