Cipher Text to Be Transmitted and Cryptanalysis in Network Security

In this paper, the authors propose an encryption algorithm to encrypt plaintext to cipher text. They divide plaintext into numeric and non-numeric fields, also, they pack the numeric fields to produce packed numeric table and combine it with symbol fields to produce the new plaintext. They apply the basic computing operations, e.g., inserting dummy symbols, rotating, transposition, shifting and complement, in the proposed algorithm to encrypt plaintext to cipher text. The produced the cipher text which contains the plaintext, relative data and tables of encryption is transmitted to the receiver through the network. They also propose the cryptanalysis about these algorithms. It can be shown that the proposed algorithm is more secure in network security.
