Set Up

In this chapter, we introduce public-key encryption. We first consider the motivation behind the concept of public-key cryptography and introduce the hard problems on which popular public-key encryption schemes are based. We then discuss two of the best-known public-key cryptosystems, RSA and ElGamal. For each of these public-key cryptosystems, we discuss how to set up key pairs and perform basic encryption and decryption. We also identify the basis for security for each of these cryptosystems. We then compare RSA, ElGamal, and elliptic-curve variants of ElGamal from the perspectives of performance and security. Finally, we look at how public-key encryption is used in practice, focusing on the popular use of hybrid encryption.

Hyper Elliptic Curve

This system provides an insight into developing a distributed system which is secure, robust and user friendly. This thesis suggests a design and implementation of a digital envelope that combines the hashing algorithm of MD5, the symmetric key algorithm of AES and the asymmetric key algorithm of Hyper Elliptic Curve. A hybrid algorithm is designed, combining the best of both AES and ECC over GF(p) cryptography. The MD5 hash algorithm is adopted to ensure integrity of the data. Cryptography (HECC). This paper discusses securing the data in clouds through implementing the key for encryption and decryption using hyper elliptical curve cryptography. The focus is on Advanced Encryption Standard (AES), the most commonly used secret key cryptographic algorithm, and Hyper Elliptic Curve Cryptography (HECC), public key cryptographic algorithms which have gained popularity in the recent years and are replacing traditional public key cryptosystems, such as RSA and ECC. Such techniques are necessary in order to use high security cryptographic algorithms in real world applications.

As the internet provides access to millions of communications in every second around the world, security implications are tremendously increasing. Transfer of important files like banking transactions, tenders, and e commerce require special security and authenticated mechanism in its journey from the sender to the receiver. Recent attention of cryptography is mainly focused on use of elliptic curves in public key cryptosystems. The present paper explains an innovative public key cryptographic scheme for protecting sensitive of critical information using elliptic curve over finite field. This mechanism besides providing the robustness of the cipher contributes the authentication of the message with digital signature.
