Breaking the Symmetry: a Way to Resist the New Differential Attack
multivariate public key cryptography Matsumoto-Imai differential symmetry projection fixing
2008/5/28
sflash had recently been broken by Dubois, Stern, Shamir,
etc., using a differential attack on the public key. The C¤− signature
schemes are hence no longer practical.
