An Effective and Secure Key Management Scheme in Multiphase Cryptosystem

One of the important aspects of network security is the security of data being communicated.  The secret data can be obtained by unwanted users for poisonous purpose therefore its essential to apply efficient encryption algorithm to increase data security like Multiphase Encryption algorithm using an efficient technique for managing keys being used for encryption and decryption.  This paper mainly focuses on implementation of the multiphase cryptosystem using AES, 3DES and management of keys using RSA algorithm.
