cryptography


The practise and study of ef="module.php?name=Lexikon&file=search&eid=1&query=encryption">encryption and ef="module.php?name=Lexikon&file=search&eid=1&query=decryption">decryption - encoding data so that it can only be decoded by specific individuals. A system for encrypting and decrypting data is a cryptosystem. These usually involve an ef="module.php?name=Lexikon&file=search&eid=1&query=algorithm">algorithm for combining the original data ("ef="module.php?name=Lexikon&file=search&eid=1&query=plaintext">plaintext") with one or more "keys" - numbers or strings of characters known only to the sender and/or recipient. The resulting output is known as "ef="module.php?name=Lexikon&file=search&eid=1&query=ciphertext">ciphertext". The security of a cryptosystem usually depends on the secrecy of (some of) the keys rather than with the supposed secrecy of the ef="module.php?name=Lexikon&file=search&eid=1&query=algorithm">algorithm. A strong cryptosystem has a large range of possible keys so that it is not possible to just try all possible keys (a "ef="module.php?name=Lexikon&file=search&eid=1&query=brute force">brute force" approach). A strong cryptosystem will produce ciphertext which appears random to all standard statistical tests. A strong cryptosystem will resist all known previous methods for breaking codes ("ef="module.php?name=Lexikon&file=search&eid=1&query=cryptanalysis">cryptanalysis").
