SECURE TRANSACTION SYSTEM

Abstract

Encryption is an essential tool for protecting the confidentiality of data. Network security protocols such as
SSL or IPSec use encryption to protect Internet traffic from eavesdropping. Encryption is also used to
protect sensitive data before it is stored on non-secure disks or tapes. Encryption, however, is
computationally expensive. A computer server that must encrypt data for thousands of clients before sending
it over the network can easily become crypto-bound. The capacity of the server is then determined by the
speed at which it can perform encryption. DES and Triple-DES are very widely used, it is important to
optimize the performance of these algorithms. Triple-DES (TDES) is basically used in various cryptographic
applications and wireless protocol security layers. The main objective of the project is to provide secured
communication.
