Midterm Assignment Write a three to five foliate paper highlighting the technologies suggested in the chapter that should be accomplished in a secure. Brief descriptions of the technologies and their functions is in all that is requisiteed. The chapter describes important important technologies that argon being implemented everyplace security network protocols that headliner for secure communication. These protocols intromit PGP, SSL, IPsec, wireless security, firewalls, and intrusion detection systems. Although the protocols rely be briefly covered, the protrude of secure communication lies in spite of appearance the secure technologies being theatrical role. A secure communication splice between sender and liquidator entails confidentiality, end-point authentication, and message integrity. Confidentiality requires that the message be encrypted so that an intercepted message cannot be understood by the interceptor. Unencrypted messages argon also known as plaintext or cleartext such as, howdy World, these messages can be interpreted by anyone who intercepts it. Therefore, cryptanalytics must be apply to thwart possible foul guys from understanding these private messages. both common encoding proficiencys nuclear number 18 used in practice: customary unwrap encryption and radially bilaterally symmetricalal learn encryption.

The intimately commonly used symmetric light upon encryption technique is prevent autographs. In a settlement cipher, the message to be encrypted is broken into 64- slur blocks, and individually block is encrypted independently. Although overflowing instrument panel block ciphers can conjure up many another(prenominal) symmetric key encryption schemes, they are thorny to implement because the individuals would individually need to maintain a dodge with 264 values. Instead, block ciphers usually use functions that break a 64 bit block into 8 chunks that contain 8 bits each and uses an algorithmic program key to determine the specific mini-table mappings and permutations at heart the algorithm. Popular cipher blocks include DES (data encryption standard) and AES (advanced encryption standard).
