WebApr 6, 2024 · Researchers Identify ‘Master Problem’ Underlying All Cryptography. The existence of secure cryptography depends on one of the oldest questions in computational complexity. In 1868, the mathematician Charles Dodgson (better known as Lewis Carroll) proclaimed that an encryption scheme called the Vigenère cipher was “unbreakable.”. WebKey in Cryptography. In cryptography, a key is a piece of information (a parameter) that determines the functional output of a cryptographic algorithm or cipher. Without a key, the algorithm would produce no useful result. In encryption, a key specifies the particular transformation of plaintext into ciphertext, or vice versa during decryption.
