Optimized Approach for Secure Communication Using DES Algorithm

Abstract

Abstract-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.

Advanced approach for encryption using advanced encryption standard with chaotic map

“…Information is confronted with various challenges primarily owing to the Internet, which has transformed the world into a small village, where numerous illegal methods are used to obtain information. Accordingly, the subject of security has become extremely critical for information protection, in which many security algorithms are used to achieve safety goals, and that the various aims of secure systems include authentication, confidentiality, and data integration [1]. In this current research a new method has been developed to improve advanced encryption standard (AES) algorithm.…”

“…1709 Cryptographic algorithms that are considered security algorithms involve two technicalities: symmetric and asymmetric cryptography [1]. Encipherment is a process that converts original text to unclear text, whereas decryption is the reverse of this process [3].…”
