INTRODUCTION

Public key cryptography is based on asymmetric cryptographic algorithms that use two related keys, a public key and a private key Given the public key, it is computationally infeasible to derive the private key. Users publish their public keys in a public directory, such as an lightweight directory access protocol (LDAP) directory and keep their private keys to themselves.

According to the purpose of the algorithm, there are public key encryption–decryption algorithms and signature algorithms. An encryption algorithm could be used to encrypt a data (for example, a symmetric key) using the public key ...
