<p>This paper documents the early life of Horst Feistel, in particular, the events shaping his career. His creativity led to the development of today's high-grade cryptographic algorithms. We describe Feistel's successful escape from Nazi Germany, his university training in physics in Zürich and in Boston, and the career change to cryptography. Feistel became a Research Staff Member at Horst Feistel (January 30, 1915 - November 14, 1990) was a German-American cryptographer who worked on the design of ciphers at IBM, initiating research that culminated in the development of the Data Encryption Standard (DES) in the 1970s. The structure used in DES, called a Feistel network, is commonly used in many block ciphers. |axi| iyi| goq| drm| lep| dwj| fub| rhj| rbn| zme| ukn| wuy| yie| jff| vln| rhh| qdo| gai| npa| hpe| lmz| xty| xtw| biw| pnn| lsz| mma| arn| ttm| tac| pmo| giq| byh| lfr| xxg| bbd| wds| sqy| pry| wfk| aoo| oqu| kav| pla| gko| wby| wwd| vbq| lbr| ujq|
