Cryptography vs security
WebMay 10, 2024 · It gives the notion of computational security of private-key encryption at first which comes from perfect security and statistical security. Let ( E, D) be an encryption scheme that uses n -bits keys to encrypt l ( n) -length messages. ( E, D) is computationally secure if E U n ( x 0) ≈ E U n ( x 1) Cryptography is the art of keeping information secure by transforming it into form that unintended recipients cannot understand.
