Extbasis
http://cjc.ict.ac.cn/quanwenjiansuo/2012-4/tmm.pdf WebConcretely, the lattice basis delegation algorithm ExtBasis() is used for intra-generation signature and the new lattice basis delegation algorithm BasisGet() is used for intergeneration signature. Scheme analysis shows the correctness and homomorphic property of the proposed schemes.
