Comparative Analysis of the RSA and AES Algorithms as Data Cryptosystems

Data encryption IS defined as a method of transforming information into a coded format, ensuring that only authorized individuals can successfully decode and comprehend the content. In addition, cryptography is principally categorized into two distinct types: symmetric key cryptography and asymmetric key cryptography. In this research, we conduct a comparative analysis of two cryptographic systems: RSA (asymmetric) and AES (symmetric key), specifically evaluating their performance in data encryption for point-to-point communications. The analysis focuses on the speed of file encryption and decryption as well as the length of the encrypted data. Experimental results reveal that both RSA and AES are robust encryption algorithms; however, AES outperforms RSA in terms of both encryption and decryption speeds while also producing a smaller remaining data size that could not be encrypted due. Finally, the paper has outlined strengths and weaknesses of reviewed algorithms which make it possible to effectively put these algorithms together in protecting information and satisfying the security needs of applications.
