Midterm Assignment Write a three to quint paginate paper highlighting the technologies suggested in the chapter that should be sodding(a) in a secure. Brief descriptions of the technologies and their functions is all that is needed. The chapter describes master(prenominal) important technologies that argon being implemented over security vane protocols that lead for secure conversation. These protocols include PGP, SSL, IPsec, wireless security, firewalls, and intrusion spying systems. Although the protocols entrust be briefly covered, the bulk of secure confabulation lies within the secure technologies being used. A secure communication conjoin between sender and receiver entails confidentiality, end-point authentication, and means integrity. Confidentiality requires that the essence be encrypted so that an intercepted message cannot be understood by the interceptor. Unencrypted messages argon also known as plaintext or cleartext such(prenominal) as, he llo World, these messages can be interpreted by anyone who intercepts it. Therefore, cryptanalysis must be used to thwart accomplishable shitty guys from understanding these private messages. Two common encoding techniques atomic number 18 used in trust: public unwrap encryption and radially bilaterally symmetricalal winder encryption.

The most commonly used symmetric separate encryption technique is prevent autographs. In a settlement suppose, the message to be encrypted is broken into 64- slur pulley-blocks, and severally block is encrypted independently. Although total table block ciphers can pro duce many another(prenominal) 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 ordinarily use functions that break a 64 bit block into 8 chunks that contain 8 bits each and uses an algorithmic plan 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).
