Stream encryption is a\npractically important     means to this end. This monograph is\ndevoted to a new aspect of stream      ciphers, namely the\nstability theory of stream ciphers, with the purpose    of\ndeveloping bounds on complexity which can form part of the\nbasis for a general theory of data security and of\nstabilizing stream-cipher          systems.\nThe approach adopted in this monograph is new. The topic           is\ntreated by introducing measure indexes on the security of\nstream     ciphers, developing lower bounds on these indexes,\nand establishing         connections among them. The treatment\ninvolves the stability of boolean     functions, the stability\nof linear complexity of key streams, the period    stability of\nkey streams, and the stability of source codes.                Misleading\nideas about stream ciphers are exposed and new                   viewpoints\npresented.\nThe numerous measure indexes and bounds on them   that are\nintroduced here, the approach based on spectrum techniques,\nandthe ten open problems presented will all be useful to\nthe reader concerned  with analyzing and designing stream\nciphers for securing data.\u003c\/p\u003e \u003ch3\u003eDetails\u003c\/h3\u003e \u003cp\u003ePublished by: Springer\u003c\/p\u003e \u003cp\u003ePublication Date: 1991-12-04\u003c\/p\u003e \u003cp\u003eFormat: Paperback\u003c\/p\u003e \u003cp\u003eISBN-13: 9783540549734\u003c\/p\u003e \u003cp\u003eDOI: 10.1007\/3-540-54973-0\u003c\/p\u003e \u003cp\u003eDimensions: 235cm x155cm\u003c\/p\u003e \u003cp\u003ePages: 194\u003c\/p\u003e ","brand":"Springer Berlin Heidelberg","offers":[{"title":"Default Title","offer_id":45369862094988,"sku":"9783540549734","price":49.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/9545\/1788\/files\/9783540549734.jpg?v=1773966035","url":"https:\/\/fh90cf-fv.myshopify.com\/products\/9783540549734","provider":"Late Knight Books and Services, LLC","version":"1.0","type":"link"}
