Cryptography is the study of how to create secure systems for communications. Cryptanalysis is the study of how to break those systems. The conflict between these two halves of cryptology is the story of secret writing. For over two thousand years governments, armies, and now individuals have wanted to protect their messages from the ?enemy?. This desire to communicate securely and secretly has resulted in the creation of numerous and increasingly complicated systems to protect one's messages. On the other hand, for every new system to protect messages there is a cryptanalyst creating a new technique to break that system. With the advent of computers the cryptographer seems to finally have the upper hand. New mathematically based cryptographic algorithms that use computers for encryption and decryption are so secure that brute-force techniques seem to be the only way to break them ? so far. This work traces the history of the conflict between cryptographer and cryptanalyst, explores in some depth the algorithms created to protect messages, and suggests where the field is going in the future. 410 0$aSpringerBriefs in computer science. 606 $aData encryption (Computer science)$xHistory 606 $aCryptography$xHistory 615 0$aData encryption (Computer science)$xHistory. 615 0$aCryptography$xHistory. 676 $a004.09 676 $a652.8 676 $a652.809 700 $aDooley$b John F$4aut$4http://id.loc.gov/vocabulary/relators/aut$0861744 801 0$bMiFhGG 801 1$bMiFhGG 906 $aBOOK 912 $a9910437573303321 996 $aA Brief History of Cryptology and Cryptographic Algorithms$92536716 997 $aUNINA
