RSA is an algorithm suitable for message authentication. It also maintains integrity of the message. The RSA Digital Signature Algorithm applied on the encrypted data and a digital signature is produced. The digital signature maintains authentication as well as integrity. This is one approach. The Secured Hash Algorithm SHA-3 Keccak is applied on the encrypted data and a message digest is produced. The RSA Digital Signature Algorithm is applied on the message digest and a digital signature is produced. This is another one approach to maintain authentication and integrity. This paper compares the performance of these two approaches.
