Strongly Unforgeable Signatures and Hierarchical Identity-Based Signatures from Lattices without Random Oracles
Abstract. We propose a variant of the “bonsai tree” signature scheme, a latticebased existentially unforgeable signature scheme in the standard model. Our construction offers ...

Short Signatures Without Random Oracles
We describe a short signature scheme that is strongly existentially unforgeable under an adaptive chosen message attack in the standard security model. Our construction works in g...

Two-Tier Signatures, Strongly Unforgeable Signatures, and Fiat-Shamir Without Random Oracles
We provide a positive result about the Fiat-Shamir (FS) transform in the standard model, showing how to use it to convert threemove identification protocols into two-tier signatur...

Security Proof of Sakai-Kasahara's Identity-Based Encryption Scheme
Abstract. Identity-based encryption (IBE) is a special asymmetric encryption method where a public encryption key can be an arbitrary identifier and the corresponding private decr...
