Midterm Assignment Write a three to five paginate paper highlighting the technologies suggested in the chapter that should be urbane in a secure. Brief descriptions of the technologies and their functions is all that is needed. The chapter describes primary(prenominal) important technologies that argon being implemented over security web protocols that lead for secure parley. These protocols include PGP, SSL, IPsec, wireless security, firewalls, and intrusion perception 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 pass along integrity. Confidentiality requires that the core be encrypted so that an intercepted message cannot be understood by the interceptor. Unencrypted messages argon also known as plaintext or cleartext such as, hello World, these messages can be interpreted by anyone who intercepts it. Therefore, cryptanalysis must be used to thwart practicable shitty guys from understanding these private messages. Two common encoding techniques atomic number 18 used in use: public unwrap encryption and radially interchangeableal identify encryption.

The most commonly used symmetric tell encryption technique is prevent autographs. In a settlement autograph, the message to be encrypted is broken into 64- slur keep mums, and to each one block is encrypted independently. Although exuberant table block ciphers can produce many another (prenominal) symmetric key encryption scheme! s, they are difficult to implement because the individuals would each need to maintain a table with 264 values. Instead, block ciphers commonly use functions that break a 64 bit block into 8 chunks that contain 8 bits each and uses an algorithmic chopine 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).
