Identity-Based Encryption from the Weil Pairing

چکیده
We propose a fully functional identity-based encryption scheme (IBE). The scheme has chosen ciphertext security in the random oracle model assuming a variant of the computational DiffieHellman problem. Our system is based on bilinear maps between groups. The Weil pairing on elliptic curves is an example of such a map. We give precise definitions for secure identity based encryption schemes and give several applications for such systems.

Identity-Based Cryptography
We review briefly about identity-based encryption and decryption. In 1984 Adi Shamir requested a solution for a novel public-key encryption scheme, called identity-based encryption. The original motivation for identity-based encryption was to help the deployment of a public-key infrastructure. The idea of an identity-based encryption scheme is that the public key can be any arbitrary string, fo...
متن کاملPairing-Based Cryptography at High Security Levels
In recent years cryptographic protocols based on the Weil and Tate pairings on elliptic curves have attracted much attention. A notable success in this area was the elegant solution by Boneh and Franklin [7] of the problem of efficient identity-based encryption. At the same time, the security standards for public key cryptosystems are expected to increase, so that in the future they will be cap...
متن کاملCertification of Public Keys within an Identity Based System
We investigate a number of issues related to the use of multiple trust authorities in the type of identifier based cryptography enabled by the Weil and Tate pairings. An example of such a system is the Boneh and Franklin encryption scheme. We examine how to create an efficient hierarchy of multiple trust authorities and then go on to examine some application areas of pairing based cryptography.
متن کاملProvable Efficient Certificateless Public Key Encryption
Certificateless public key cryptography was introduced to overcome the key escrow limitation of the identity-based cryptography. It combines the advantages of the identity-based cryptography and the traditional PKI. Recently, Dae Hyun Yum1 and Pil Joong Lee have proposed a generic series construction model of certificateless public key encryption (CL-PKE) which is built from generic primitives:...
متن کاملAn Identity-based Mediated Signature Scheme from Bilinear Pairing
It has always been a critical issue to find efficient methods for fast revocation of a user’s identity in identity (ID)based cryptosystems. Unfortunately, none of the previous ID-based cryptography can find a practical way. Libert et al. and Baek et al. respectively propose an ID-based mediated encryption scheme based on the practical ID-based encryption scheme from bilinear pairing due to Bone...
