Vol. 18  No. 11  pp. 159-166


A modified version of the Advanced Encryption Standard algorithm is developed here for the aim of security and easier implementation. As the cloud users and communications over the network are increasing tremendously and therefore the users also would like faster storing and access to data on the cloud, it's become the key issue to provide security. Advanced Encryption Standard (AES) is a vastly used technique for providing security. This algorithm is modified to make it efficient but some security needs to be compromised. Here a different key generation process is used. Transpose is introduced and MixColumn process is eliminated for removing complex calculation. Thus, it provides a less complex technique as compared to the main algorithm. It will be easily implemented within the cloud as well as for hiding info in the personal computer.
