Aiming for the efficient encryption/decryption and digital signature in the resource restricted environments,a solution for reducing public and private key spaces and amount of data transmitted over network is investigated with the help of number theory and algebraic theory.
为了满足在带宽受限制且带宽费用高的受限制环境下,实施高效率的加密解密与数字签名的需要,使用了数论、近世代数、算法分析等工具,研究节省公钥、私钥存储量和传输信息量的方案。
