Question

Quizplus · Accepted Answer

The block cipher that operates on 64-bit blocks of plaintext and was developed by Bruce Schneier is Blowfish. Therefore, the correct choice is D. AES operates on 128-bit blocks of plaintext, RC5 operates on variable-length blocks, and IDEA operates on 64-bit blocks as well but was not developed by Bruce Schneier.
