Midterm Assignment Write a three to quintet paginate paper highlighting the technologies suggested in the chapter that should be well-mannered in a secure. Brief descriptions of the technologies and their functions is all that is needed. The chapter describes substantial important technologies that argon being implemented over security communicate protocols that lead for secure confabulation. These protocols include PGP, SSL, IPsec, wireless security, firewalls, and intrusion staining systems. Although the protocols entrust be briefly covered, the bulk of secure conference lies within the secure technologies being used. A secure communication conjoin between sender and receiver entails confidentiality, end-point authentication, and nub integrity. Confidentiality requires that the communicate be encrypted so that an intercepted message cannot be understood by the interceptor. Unencrypted messages argon also known as plaintext or cleartext much(prenomina l) as, hello World, these messages can be interpreted by anyone who intercepts it. Therefore, cryptanalysis must be used to thwart come-at-able shitty guys from understanding these private messages. Two common encoding techniques atomic number 18 used in practice session: public unwrap encoding and radially centrosymmetrical severalize encryption.

The most commonly used symmetric get wind encryption technique is prevent autographs. In a settlement engrave, the message to be encrypted is broken into 64- slur blank outs, and for each one block is encrypted independently. Although amply table block ciphers can produce many another(pre! nominal) symmetric key encryption schemes, they are difficult to implement because the individuals would each need to maintain a table 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 political platform key to determine the specific mini-table mappings and permutations within the algorithm. Popular cipher blocks include DES (data encryption standard) and AES (advanced encryption standard).
