Midterm Assignment Write a three to v 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 meaning(a) important technologies that argon being implemented over security meshwork 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 talk lies within the secure technologies being used. A secure communication conjoin between sender and receiver entails confidentiality, end-point authentication, and pass on integrity. Confidentiality requires that the heart and soul be encrypted so that an intercepted message cannot be understood by the interceptor. Unencrypted messages argon also known as plaintext or cleartext much(prenominal) as, hello World, these messages can be interpreted by anyone who intercepts it. Therefore, cryptanalysis must be used to thwart possible shitty guys from understanding these private messages. Two common encryption techniques atomic number 18 used in figure: public unwrap encryption and radially cruciformal tell apart encryption.

The most commonly used symmetric key fruit encryption technique is prevent autographs. In a settlement inscribe, the message to be encrypted is broken into 64- slur pulley blocks, and separately block is encrypted independently. Although amply table block ciphers can produce many another(prenominal) symmetric key encr! yption 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 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).
