This document proposes and compares two encryption algorithms, triple data encryption standard (3DES) and Rivest Shamir Adlemen (3kRSA), for securing data in cloud computing. The algorithms are implemented on the cloud operating system EyeOS. A comparative study finds that 3kRSA outperforms 3DES in complexity and output bytes, while 3DES is faster. Both algorithms encrypt data to provide confidentiality and integrity for data stored and transmitted over the insecure cloud environment. The document provides background on cloud security, the two algorithms, and the experimental setup using EyeOS for evaluation.
