A New Hierarchical Identity-based Signature Scheme From Lattices In The Standard Model
Hierarchical identity-based signature (HIBS), which plays an important role in large communities, is a generalization of identity-based signature (IBS). In this paper, we present a new HIBS scheme from lattices without random oracles. The new scheme is proven to be strongly unforgeable against selective identity attacks under the standard hardness assumption of the short integer solution (SIS) ...
متن کاملSecure Identity-Based Blind Signature Scheme in the Standard Model
The only known construction of identity-based blind signature schemes that are secure in the standard model is based on the generic approach of attaching certificates to ordinary (i.e. non-identity-based) blind signature schemes, and thus the identity-based blind signature schemes constructed using this method are somewhat inefficient and have long signature size. In this paper, we present the ...
متن کاملIdentity-Based Encryption from Lattices in the Standard Model
We construct an Identity-Based Encryption (IBE) system without random oracles from hard problems on random integer lattices. The system is anonymous, with pseudo-random ciphertexts.
متن کاملEfficient identity-based threshold signature scheme from bilinear pairings in the standard model
We propose a new identity-based threshold signature (IBTHS) scheme from bilinear pairings enjoying the following advantages in efficiency, security and functionality. The round-complexity of the threshold signing protocol is optimal since each party pays no other communication cost except broadcasting one single message. The computational complexity of the threshold signing procedure is conside...
متن کاملFuzzy Identity Based Encryption from Lattices
Cryptosystems based on the hardness of lattice problems have recently acquired much importance due to their average-case to worst-case equivalence, their conjectured resistance to quantum cryptanalysis, their ease of implementation and increasing practicality, and, lately, their promising potential as a platform for constructing advanced functionalities. In this work, we construct “Fuzzy” Ident...
