WebFirst, it assures us that attacks on the cryptographic construction are likely to be eﬀective only for small choices of parameters and not asymptot- ically. In other words, it assures us that there are no fundamental ﬂaws in the design of our cryptographic construction. WebIt explains how programmers and network professionals can use cryptography to maintain the privacy of computer data. Starting with the origins of cryptography, it moves on to explain cryptosystems, various traditional and modern ciphers, public key encryption, data integration, message authentication, and digital signatures.
