The National Institute of Standards and Technology is in the process of selecting one or more public-key cryptographic algorithms through a public competition-like process. The new public- key cryptography standards will specify one or more additional

Weak is Better: Tightly Secure Short Signatures from Weak PRFs

June 7, 2017

Author(s)

Jacob M. Alperin-Sheriff, Daniel Apon

The Boyen-Li signature scheme [Asiacrypt'16] is a major theoretical breakthrough. Via a clever homomorphic evaluation of a pseudorandom function over their verification key, they achieve a reduction loss in security linear in the underlying security
