摘要
Group key management technique is a fundamental building block for secure and reliable group communication systems.In order to successfully achieve this goal, group session key needs to be generated and distributed to all group members in a secure and authenticated manner.The most commonly used method is based on Lagrange interpolating polynomial over the prime field F p={0,1,2,…, p-1}. A novel approach to group key transfer protocol based on a category of algebraic-geometry code is presented over the infinite field GF(2 m). The attractive advantages are obvious. Especially, the non-repeatability, confidentiality, and authentication of group key transfer protocols are obtained easily. Besides, a more generalized and simple mathematical construction model is proposed which also can be applied perfectly to related fields of information security.

A novel approach to group key transfer protocol based on a category of algebraic-geometry code is presented over the infinite field GF(2~m). The attractive advantages are obvious. Especially, the non-repeatability, confidentiality, and authentication of group key transfer protocols are obtained easily. Besides, a more generalized and simple mathematical construction model is proposed which also can be applied perfectly to related fields of information security.
