WebA typical application of cryptography is secure communication. Informally a secure communication channel is one that provides both confidentiality and Integrity of the messages. In this section we investigate confidentiality, therefore we may assume that integrity is already guaranteed by some other means. ... A symmetric encryption scheme . … WebAug 5, 2024 · In this challenge, we are given the source code of an encryption scheme that uses matrix operations for encryption and decryption, the corresponding encrypted flag and some hints. For the encryption part: \[E = L^{-1}Y = L^{-1}SX = L^{-1}LU(A+R) = U(A+R)\] The three hints we have is $LUL$, $L^{-1}S^2L$ and $R^{-1}S^8$
