WebIn cryptography, an S-box ( substitution-box) is a basic component of symmetric key algorithms which performs substitution. In block ciphers, they are typically used to obscure the relationship between the key and the ciphertext, thus ensuring Shannon's property of confusion. Mathematically, an S-box is a nonlinear [1] vectorial Boolean function.

WebMar 5, 2016 · A main goal in cryptography is to prove the security of cryptographic schemes. This means that one wants to prove that the computational problem of breaking the scheme is infeasible, i.e., its solution requires an amount of computation beyond the reach of current and even foreseeable future technology. Before the modern era, cryptography focused on message confidentiality (i.e., encryption)—conversion of messages from a comprehensible form into an incomprehensible one and back again at the other end, rendering it unreadable by interceptors or eavesdroppers without secret knowledge (namely the key needed for decryption of that message). Encryption attempted to ensure secrecy
