Research on Certificate Cooperating Signature Scheme in Mobile Ad Hoc Networks
Lei Sun, Xuandong Xiong · 2008
Distribute architecture based on threshold scheme is adopted to provide certification service in Mobile Ad Hoc Networks, due to its characteristics such as no infrastructure, no center. There are some problems in those schemes such as fixed threshold value and conspiracy attack. A certificate signature scheme based on threshold group signature is proposed in this paper, comparing to existing distributed certificate signature algorithm, which not only can withstand conspiracy attack, but also can change threshold value conveniently on demand.
