Abstract
If X is sender of a message and Y is the receiver of the same, then X encrypts the same with Y’s public key and then sends the encrypted data to Y. It confirms about authenticity and authorization of receiver. If X sends message and Y receives, X encrypts the message with X’s private key and sends the encrypted data to Y. It confirms authenticity and authorization of the sender [1]. Such a schema could work properly. It involves the usage of a message digest or hash. Hash is a fingerprint or the summary of the message. It carries similar concept of cyclic redundancy check (CRC). Integrity of the data is verified with this process. This process actually confirms that the data should not be damaged between the path of sender and receiver [2]. Hashing confirms few things like (i) complexity of calculation of hash value of a message should be decreased; (ii) it follows a one-way encrypting procedure or technique; and (iii) different hash values should be generated by a particular hashing technique for any two different messages.
