Abstract
Data has been a very important aspect in the execution of human activity since the start of the last century. Due to advancements of different applications and emergence of variety of services, there has been a substantial growth in the amount of data in the last few years. Cloud storage has emerged as one of the most widely adopted technologies throughout the recent years in business environments. The issues that were raised bordered on security of data, privacy of data and other aspects of Data protection even though the cloud is said to be becoming available and appealing. There is no doubt that data privacy and security in a cloud is a major concern when it comes to cloud computing. Indeed, a majority of people who have problems with cloud storage are worried about privacy and security. This paper offers a comparison between RSA, AES, and a method using both RSA and AES the performance of these techniques according to encryption and decryption time for different sizes of data sets is discussed. Carried out on standardized devices in the Mathematica writing and analysis tool based on the Wolfram Language, the experiment was designed for replicability. For this experiment, data sizes of 64 to 176 bytes were transmitted and encryption and decryption times were measured and compared. The number of iterations performed by each algorithm was also measured to provide a second measure of the performance of the algorithms. Findings show that AES had the shortest encryption and decryption time and the results also shows how the hybrid model implemented the best of both RSA and AES with regards to security and speed. The hybrid method offered a balanced performance, with encryption times of 0.10 ms and 0.20 ms for 64-byte and 176-byte data, respectively. AES achieved a throughput improvement of up to 2x compared to the hybrid method and 4x compared to RSA. These findings suggest that while AES is optimal for speed, the hybrid approach balances speed and security effectively
