Padding oracles and the decline of CBC-mode cipher suites

WebDefinition. A block cipher consists of two paired algorithms, one for encryption, E, and the other for decryption, D. Both algorithms accept two inputs: an input block of size n bits and a key of size k bits; and both yield an n-bit output block.The decryption algorithm D is defined to be the inverse function of encryption, i.e., D = E −1.More formally, a block … WebCipher Block Chaining (CBC) Security Encryption mode is cipher block chaining. It is vulnerable to timing attack (eg: Lucky Thirteen attack) and padding oracle attack (eg: POODLE attack).
