It presents a wide range of topics for a thorough understanding of the factors that affect the efficiency of secrecy, authentication, and digital signature schema. Most importantly, readers gain hands-on experience in cryptanalysis and learn how to create effective cryptographic systems. The author contributed to the design and analysis of the Data Encryption Standard (DES).Computer securityCryptographyComputer security.Cryptography.005.8Konheim Alan G.1934-27808MiAaPQMiAaPQMiAaPQBOOK9911020105403321Computer security and cryptography4416290UNINA01920oas 22006853a 450 991089094650332120251105213014.01546-2056(DE-599)ZDB2157563-0(OCoLC)52924944(CONSER) 2003212820(CKB)111088195271990(EXLCZ)9911108819527199020030827b20042005 sy aengurcnu||||||||txtrdacontentcrdamediacrrdacarrierMechanics & chemistry of biosystems MCBEncino, CA Tech Science Press2004-2005Title from cover image (publisher's Web site, viewed June 22, 2005).Place of publication varies: Forsyth, Ga., -v. 2, no. 2.1546-2048 MCB onlineMechanics & chemistry of biosystems online versionMechanics and chemistry of biosystemsMCBBiomechanicsPeriodicalsBiochemistryPeriodicalsBioengineeringPeriodicalsBiochemistryfast(OCoLC)fst00831961Bioengineeringfast(OCoLC)fst00832028Biomechanicsfast(OCoLC)fst00832558Periodicals.fastBiomechanicsBiochemistryBioengineeringBiochemistry.Bioengineering.Biomechanics.540NSDNSDOCLCQNSDDLCNSDCUIOCLCQOCLCFOCLCOOCLCQOCLCOOCLCLOCLCQJOURNAL9910890946503321Mechanics & chemistry of biosystems4244209UNINA
