Secure File Storage on Cloud Using Hybrid Cryptography

Abstract

For decades, cloud computing has empowered the wide spread and storage of information. Its evolution has provisioned concepts for ubiquitous computing enabling accessibility to individual records without barriers to location. However, the proliferation of cloud computing provision a forum for cybercriminal to experiment. Lately, cyber-crimes proliferation has been of great concern to researchers. This have given this study the impetus to evaluate the performance of the Chacha20 and ECC algorithm while hybridizing it with added layer of security. The performance of the algorithms was evaluated against some metric including the file size and encryption and decryption time. The implemented algorithms were further compared with some of the state-of-the-art algorithm. The comparison shows that the implemented ECC and Chacha20 algorithm performed better compared to some of the compared state of the art algorithm.
