Data Encryption and Authetication Using Public Key Approach

AbstractToday various numbers of diverse applications that include e- payments in secure commerce and payment applications to provide security for their communications and transactions by protecting passwords. Encryption is a fundamental tool for the protection of sensitive information. The purpose is to use encryption is privacy for preventing disclosure or confidentiality in during communications. In this paper, we proposed a new method which is based on the Euler's Totient theorem to produce a set of numbers that encrypt the data stream and then we used our proposed method using an ECC approach to generate the signature key which is added to encrypt data before transmission and decryption operation and a signature can verify at the receiver site

Image Encryption Using Elliptic Curve Cryptograhy and Matrix

AbstractThe enlarged size of the internet and vast communication across it and also medical needs digital images require of security plays vital role. So different techniques are used to protect confidential image data from unauthorized access. In this paper, we propose a New encryption technique Using elliptic curve cryptography with a magic matrix operations for securing images that transmits over a public unsecured channel. There are two most important groups of image encryption algorithms: some are non chaos-based selective methods and chaos- based selective methods. The majority of these algorithms is planned for a specific image format, compressed or uncompressed
