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...

Short Signatures from Weaker Assumptions
We provide constructions of (m, 1)-programmable hash functions (PHFs) for m ≥ 2. Mimicking certain programmability properties of random oracles, PHFs can, e.g., be plugged into ...

Short and Stateless Signatures from the RSA Assumption
We present the first signature scheme which is “short”, stateless and secure under the RSA assumption in the standard model. Prior short, standard model signatures in the RSA...

Signature Schemes Based on the Strong RSA Assumption
We describe and analyze a new digital signature scheme. The new scheme is quite efficient, does not require the the signer to maintain any state, and can be proven secure against ...

Group signatures with verifier-local revocation
Group signatures have recently become important for enabling privacy-preserving attestation in projects such as Microsoft's ngscb effort (formerly Palladium). Revocation is c...
