Efficient Key Management for Data Security using AES

Abstract

Secured and timely transmission of data is always an important aspect for an organization. In the encryption process the failure rate of keys and processing time are directly related with the security of cryptographic model. The use of strong encryption algorithms almost make it impossible for a hacker to get access of node. It helps to ensure the privacy of a user from others. Secured and timely transmission of data is always an important aspect for an organization. Keeping in view the importance of keys for secure data transmission, this work incorporates the use of efficient key management in AES. This work is focused on the use of key in an efficient manner to achieve more data security. Various techniques employed for the data security with their merits and demerits have been critically analyzed. Literature survey has been carried out by considering key papers related with data security and encryption algorithms. From these papers few observations have also been drawn, which are used to formulate the problem. Finally objectives have been drawn in which key has been efficiently used. Simulation results have been achieved using MATLAB, encryption time has been reduced which makes the cryptographic model more secured in comparison to AES. Finally, comparison of the proposed scheme has been done with AES in terms of encryption and decryption time.
