Chosen Message Attack on Multivariate Signature ELSA at Asiacrypt 2017
post-quantum cryptography multivariate public-key cryptography chosen message attack
2018/4/4
One of the most efficient post-quantum signature schemes is Rainbow whose harness is based on the multivariate quadratic polynomial (MQ) problem. ELSA, a new multivariate signature scheme proposed at ...
A Practical Elliptic Curve Public Key Encryption Scheme Provably Secure Against Adaptive Chosen-message Attack
Decisional Diffie-Hellman assumption elliptic curve standard intractability paradigm
2009/4/9
We study elliptic curve cryptosystems by first investigating
the schemes defined over Zp and show that the scheme is provably secure
against adaptive chosen cipher-text attack under the decisional D...
