WebDec 6, 2024 · There are 26! permutations; so, there are 26! possible monoalphabetic substitution ciphers. The simplest substitution cipher is one that replaces each alphabet in a text by the alphabet k positions away (in the modulo 26 sense). For k = 3, the substitutions are D for A, E for B, A for X, B for Y, etc. Such a scheme is referred to as a Caesar ... WebApr 10, 2024 · When plain text is encrypted it becomes unreadable and is known as ciphertext. In a Substitution cipher, any character of plain text from the given fixed set of characters is substituted by some other character from the same set depending on a key. For example with a shift of 1, A would be replaced by B, B would become C, and so on. WebTriple DES.

WebOption 2: K1 matches K3 but K2 is different (parity bits ignored). The TDES key is 16 bytes long (concatenation of K1 and K2), to achieve 90 bits of effective security. In this mode, the cipher is also termed 2TDES. Option 3: K1 K2, and K3 all match (parity bits ignored). As result, Triple DES degrades to Single DES.
