Abstract:
E-mail is widely used all over the world in
various fields such as economic, office, personal case and so on.
It is easy to transport data from place to place in a short time.
E-mail has become one of the most important means of
communication. In this process, attackers interfere with E-mail
by feeding and accessing data and also by taking these and
transporting the false data to users. So, the mail security is
necessary by using cryptography method to protect the danger
of the attackers. In this paper, Linear Congruential
Method(LCM) and River Shamir Adleman (RSA) are used for
email encryption for lightweight for email. LCM in generating
pseudo-random numbers is used to provide an alternative
attitude for some cryptographic purpose.
