Optimized Approach for Secure Communication Using DES Algorithm
2017
Security remains a major "pain" for both individuals and large organizations in today's modern world.Everything needs security, whether it is communication through telephonic media, or transfer of data files.The security or privacy can only be ensured by applying algorithms to the data defined under Cryptography.Encryption, a mechanism which changes the plaintext to a secured form defined as scrambled text(cipher).The scrambled text, then is received and decryption is done to analyze the plaintext.This involves various types such as: symmetric or asymmetric encryption.This paper brings in an improved and optimized version of 3DES algorithm.It also lists various advantages of the new algorithm over DES and Triple-DES algorithm.A brief in between DES, Triple-DES and the newly designed algorithm (Optimized DES Algorithm) is provided taking amount of complexity, user effort required, key size and number of rounds to perform successful conversion operations as base for comparison.
