Identity Based Secure RSA Encryption System

Identity Based Encryption (IBE) has emerged as a solution to the problem of trust in public keys of Public Key Cryptography (PKC) systems where most of the proposed IBE schemes are based on bilinear pairing and Elliptic Curve Cryptography. The heavy computations involved in such schemes make pairing based schemes less practical. Efficient non-pairing schemes have been designed over the famous RSA structure to bridge the practical gap between actual public key ciphers and utility of IBE in it. Yet the security threats to RSA have been retained in such proposals. This paper presents an RSA based IBE scheme which overcomes the security problems of RSA and has linear computations involved and makes key management/revocation easy.
