HIBE With Short Public Parameters Without Random Oracle
Abstract. At Eurocrypt 2005, Waters presented an identity based encryption (IBE) protocol which is secure in the full model without random oracle. In this paper, we extend Waters&#...

Strongly Unforgeable ID-Based Signatures without Random Oracles
In this paper, we construct a strongly unforgeable ID-based signature scheme without random oracles.4 The signature size of our scheme is smaller than that of other schemes based o...

Concurrently-Secure Blind Signatures Without Random Oracles or Setup Assumptions
Abstract. We show a new protocol for blind signatures in which security is preserved even under arbitrarily-many concurrent executions. The protocol can be based on standard crypto...

Generic Constructions for Verifiably Encrypted Signatures without Random Oracles or NIZKs
Verifiably encrypted signature schemes (VES) allow a signer to encrypt his or her signature under the public key of a trusted third party, while maintaining public signature verifi...
