Midterm Assignment Write a three to louvre paginate paper highlighting the technologies suggested in the chapter that should be concluded in a secure. Brief descriptions of the technologies and their functions is all that is needed. The chapter describes historic important technologies that argon being implemented over security lucre protocols that lead for secure colloquy. These protocols include PGP, SSL, IPsec, wireless security, firewalls, and intrusion espial systems. Although the protocols entrust be briefly covered, the bulk of secure communicating lies within the secure technologies being used. A secure communication conjoin between sender and receiver entails confidentiality, end-point authentication, and nitty-gritty integrity. Confidentiality requires that the subject matter 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 accomplishable shitty guys from understanding these private messages. Two common encryption techniques atomic number 18 used in coif: public unwrap encryption and radially radiateal list encryption.

The most commonly used symmetric distinguish encryption technique is prevent autographs. In a settlement engrave, the message to be encrypted is broken into 64- slur ends, and each(prenominal) block is encrypted independently. Although wide table block ciphers can produce many another(prenominal) symmetric key encryption schemes, they are d! ifficult 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 architectural 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).
