WebA block cipher processes the data blocks of fixed size. Usually, the size of a message is larger than the block size. Hence, the long message is divided into a series of sequential message blocks, and the cipher operates on these blocks one at a time. Electronic Code Book (ECB) Mode WebIn our specific context, binary cross-entropy is a valid choice because what we are essentially doing is 2-class classification: (i) either the two sequences given as input to the network are of the same type, random or cipher output (i.e., class 1), (ii) or the two sequences are of different types (i.e, class 2). Binary cross-entropy loss is ...
