Graded Encoding, Variations on a Scheme
Cryptography Multilinear Maps Graded Encoding Multi-partite Key-Agreement
2015/12/23
In this note we provide a more-or-less unified framework to talk about the functionality and
security of graded encoding schemes, describe some variations of recent schemes, and discuss
their securi...
The Cryptographics Algorithms AES and Twofish guarantee a high diffusion
with the use of fixed MDS matrices of size 4 × 4. In this article variations to the
Cryptographics Algorithms AES and Twofish...
AN OBSERVATION ABOUT VARIATIONS OF THE DIFFIE-HELLMAN ASSUMPTION
Diffie-Hellman Assumption SBB GSBB
2009/6/11
We generalize the Strong Boneh-Boyen (SBB) signature scheme
to sign vectors (GSBB). We show that if a particular (but most natural) aver-
age case reduction from SBB to GSBB exists, then the Strong ...
Equivalent Keys in HFE, C*,and variations
Multivariate Quadratic Equations Public Key signature Hidden Field Equations
2009/4/3
In this article, we investigate the question of equivalent keys for two Multivariate Quadratic
public key schemes HFE and C*¡¡ and improve over a previously known result, to appear at
PK...
