WebThe steps are as follows −. Load the n-bit Initialization Vector (IV) in the top register. XOR the n-bit plaintext block with data value in top register. Encrypt the result of XOR … Webciphertext and some statistical knowledge of the plaintext. Aside from the fact that one should be conservative in assessing security levels, a successful known or chosen plaintext attack can often be modified to work under the ciphertext-only assumptions. Reference [5] explains one such instance, where the parity bit in the American Na- ...
