Performance Evaluation of RSA Type of Algorithm with Cuckoo Optimized Technique

Cloud technology simplifies the roles of data storage and memory starvation. But the confidentiality will become biggest challenge in the public domain. In this paper, we are proposing the concept of improving the efficiency of the existing RSA algorithm. For the performance enhancement we are implementing the cuckoo search to select the optimal key for the RSA’s encryption and decryption process. For proving we are efficient, we have identified the ECC encryption and decryption also for comparison. If we increase the key breaking time, we can maintain the confidentiality in the cloud environment. At the end we compared the performances of ECC, RSA and Improved RSA.
