Structure-Preserving Signatures on Equivalence Classes and their Application to Anonymous Credentials
Public key cryptography structure-preserving signatures attribute-based anonymous credentials
2016/1/7
Structure-preserving signatures are a quite recent but important building block for many
cryptographic protocols. In this paper, we introduce a new type of structure-preserving signatures, which
all...
EUF-CMA-Secure Structure-Preserving Signatures on Equivalence Classes
public-key cryptography structure-preserving signatures
2016/1/5
At ASIACRYPT’14 Hanser and Slamanig proposed a new primitive called structure-preserving signatures
on equivalence classes (SPS-EQ) and used it to construct very efficient attribute-based anonymous

The Pollard kangaroo method solves the discrete logarithm problem (DLP) in an interval of size $N$ with heuristic average case expected running time approximately $2 \sqrt{N}$ group operations. A rece...
