Implementation of E-mail Security System Using NTRU Cryptosystem and SHA-1 Algorithm

Abstract

Security of exchanging private information over a non secure channel is important in communications system. Efficient cryptographic techniques are necessary to endow the security level in mail system. Email security is needed to implement to send the message in a secure way. With no encryption email activity is plainly visible by any occasional eavesdropper. The Number Theory Research Unit (NTRU) cryptosystem becomes the fastest and smallest public key security solutions for data communication network and application. Email has become one of the most important means of communication and it is widely used all over the world in various fields. This system intends to implement the email security system by using NTRU cryptosystem to encrypt and decrypt mail message to provide security goal of confidentiality. Secure Hash Algorithm (SHA-1) is used to check the mail message integrity of this system
