The discrete logarithm problem is the basis for believing some other cryptosystems are secure, and again, there are related, less practical systems that are provably secure relative to the solvability or insolvability discrete log problem. The growth of cryptographic technology has raised a number of legal issues in the information age. The key is a secret (ideally known only to the communicants usually a short string of characters, which is needed to decrypt the ciphertext. Association for Computing Machinery. 58 DES was designed to be resistant to differential cryptanalysis, 59 a powerful and general cryptanalytic technique known to the NSA and IBM, that became publicly known only when it was rediscovered in the late 1980s.
