Encryption is the process of transforming information into an unidentifiable code so that only the intended recipient can access it and those who are not authorized cannot. Encryption does not itself prevent interference, but denies the intelligible content to a would-be interceptor. It can still be used to protect a user’s identity and privacy. As more and more information is stored on computers or communicated via computers, the need of the hour is to ensure that this information is secure and to prevent from snooping / tampering becomes more relevant. Even if data does end up getting stolen, it will be unreadable and nearly useless if it’s encrypted. With the fast progression of digital data exchange in electronic way, Encryption is essential for ensured and trusted delivery of sensitive information sent over the internet. Contemporary human being intelligence, lead to cryptography has become more complex in order to make information more secure. Meanwhile many encryption algorithms are being developed in the world of Cyber security society. In this paper, a hardware implementation of three standard cryptography algorithms on a universal architecture.The cryptography processor algorithm targets smart card applications and implements both private and public-key algorithms.
