A vector space group signature scheme based on ECC

As Internet technologies advance, the problem of Internet security has become increasingly urgent. This study integrates the identity authentication scheme with the vector space scheme and applies the elliptic curve cryptosystem, to construct a group signature authentication cryptosystem. The application environment is required to transmit data through the Internet, so the proposed method uses the elliptic curve cryptosystem which has a low computational cost and small key size, which can be used in an Internet environment with limited hardware resources.
