QUESTION NO: 1153 Which is a characteristic of IDEA? A. 56 bytes B. 64 bits C. 64 bytes D. All of the above E. None of the above
Answer: B Explanation: From Wikipedia: International Data Encryption Algorithm (IDEA) operates on 64-bit blocks using a 128-bit key, and consists of a series of eight identical transformations (a round, see the illustration) and an output transformation (the half-round). The processes for encryption and decryption are similar. IDEA derives much of its security by interleaving operations from different groups — modular addition and multiplication, and bitwise eXclusive OR (XOR) — which are algebraically “incompatible” in some sense.
