Question 1: What are the two general approaches to attacking a cipher? Question 2: Why is the middle portion of 3DES a decryption rather than an encryption?
With the ECB mode, if there is an error in a block of the transmitted cipher text, only the corresporrding plaintext block is affected. However, in the CBC mode, this error propagates.
