Lattice signature and its application based on small integer solution problem
Ji Cao · Journal of Computer Applications · 2014
A lattice signature scheme was proposed and some parameter choosing rules were illustrated concerning Small Integer Solution( SIS) problem and random oracle model of lattice. Then the results of the length of the keys that were generated under different parameter circumstances were compared. Afterwards the security and efficiency with the signature scheme were verified. At last, for the purpose of fairness, and reliability in multipartite authentication, the signature scheme was combined with key distribution and escrow, a new authentication scheme with the Singular Value Decomposition( SVD)algorithm based on mathematical matrix decomposition theory was proposed.
