Practical hybrid (hierarchical) identity-based encryption schemes based on the decisional bilinear Diffie-Hellman assumption
At Eurocrypt 2005, Waters proposed an efficient identity-based encryption (IBE) scheme and its extension to a hierarchical IBE (HIBE). We describe a (H)IBE scheme which improves upon Waters scheme by significantly reducing the size of the public parameters. The reduction is based on two ideas. The first idea involves partitioning n-bit identities into l-bit blocks while the second idea involves...
متن کاملIdentity-Based Encryption from the Diffie-Hellman Assumption
We provide the first constructions of identity-based encryption and hierarchical identitybased encryption based on the hardness of the (Computational) Diffie-Hellman Problem (without use of groups with pairings) or Factoring. Our construction achieves the standard notion of identity-based encryption as considered by Boneh and Franklin [CRYPTO 2001]. We bypass known impossibility results using g...
متن کاملA Note on the Bilinear Diffie-Hellman Assumption
The Bi-linear Diffie-Hellman (BDH) intractability assumption is required to establish the security of new Weil-pairing based cryptosystems. BDH is reducible to most of the older believed-to-be-hard discrete-log problems and DH problems, but there is no known reduction from any of those problems to BDH. Let the bilinear mapping be ê : G1×G1 → G2, where G1 and G2 are cyclic groups. We show that a...
متن کاملSurvey on Identity based and Hierarchical Identity based Encryption Schemes
In this paper, we present a comprehensive picture and the state of the art of Identity Based Cryptography (IBC) and their security implications with applications. First, we introduce the basic concepts of security and principles of cryptography and then move into identity-based cryptography, an overview of its development process and research progress. We explain identity-based encryption (IBE)...
متن کاملMaking the Diffie-Hellman Protocol Identity-Based
This paper presents a new identity based key agreement protocol. In id-based cryptography (introduced by Adi Shamir in [33]) each party uses its own identity as public key and receives his secret key from a master Key Generation Center, whose public parameters are publicly known. The novelty of our protocol is that it can be implemented over any cyclic group of prime order, where the Diffie-Hel...
