Providing More Security to Data Stored in Multi-Cloud Environment Using Encryption and Decryption Techniques

A developing idea, multi-cloud computing provides on-demand computing services. A corporation loses control over its data when it moves to the cloud, therefore security measures must be as high-value as the data. Multi-Cloud security is based on encryption and trusted computing. Our suggested method prevents unauthorized intruders from decrypting collected data by limiting data access to authorized users only. We evaluated the performance taking throughput, time complexity, and space complexity into account. Through the analysis of several factors, including the length of the private key and the message packet, we were able to conclude that the RSA encryption technique is a workable option for secure communication in cloud computing.
