Cryptography is the science of transmission and reception of secrete message. It has been used for providing secure communication between individuals In this paper author proposed a new method of cryptography, in which new integral transform “Elzaki Transform” is used for encrypting the plain text message and corresponding inverse transform for Decryption. KEYWORD: Cryptography, Encryption, Decryption, Elzaki transform. 1. INTRODUCTION In the present day, electronic communication such as mobile communication, e-banking, e-commerce, financial information, ATM cards, emails, etc has become an essential part of every aspect of human life. With the growing quantity of digital data stored and communicated by electronic data-processing system, it is necessary to protect information from unwanted intrusion [1]. Cryptography is the science of transmission and reception of secrete message. It has been used for providing secure communication between individuals [3, 4, 5, 6]. The fundamental objective of cryptography is to enable two people to communicate over an insecure channel in such a way that any opponent cannot understand what is being said. The communication security is gaining importance as a result of the more and more use of electronic communication in day to day activities. Cryptography is the most important tool that provides network security during electronic communication. Encryption is the process of converting or encoding original information in such a way that only authorized person can access. This is usually done for secrecy and typically for confidential communication [1, 2]. A cipher is an algorithm for performing encryption and decryption [1]. The original information is called plain text and the encrypted form as cipher text. The cipher text contains all the information of the plain text message but is not in a format readable by human or computer without proper mechanism to decrypt it. Ciphers are usually parameterized by a piece of auxiliary information called a Key [3]. The encryption procedure is varied depending on the key, which changes the detailed operation of the algorithm. Without the appropriate key the decryption is highly impossible [1, 2, 3, 4, 5, 6]. In the present paper a new cryptographic method is planned in which Elzaki transform is used for encrypting the plain text and corresponding inverse transform is used for decryption. Elzaki transform was introduced by Tarig M. Elzaki in 2011 and is widely used in applied mathematics as well as in engineering field [7, 8, 9, 10, and 11]. The plan of the paper is as follows: In section 2, we introduce definition and some standard results of Elzaki transforms, proposed method & illustrative example in 3, and conclusion in 4.
