Block substitution

WebThe encryption key for the ideal block cipher is the codebook itself, meaning the table that shows the relationship between the input blocks and the output blocks. Figure 1 depicts an ideal block cipher that uses blocks of size 4. Each block of 4 bits in the plaintext is transformed into a block of 4 ciphertext bits. 4 WebA substitution is a mutation that exchanges one base for another (i.e., a change in a single “chemical letter” such as switching an A to a G). Such a substitution could: change a codon to one that encodes a different amino acid and cause a small change in …

Working of the cipher : AES performs operations on bytes of data rather than in bits. Since the block size is 128 bits, the cipher processes 128 bits (or 16 bytes) of ... WebThe BLOSUM matrix is another amino acid substitution matrix, first calculated by Henikoff and Henikoff [ 5 ]. For its calculation only blocks of amino acid sequences with small change between them are considered. These blocks are called conserved blocks (See figure 3.2 ).
