One Key-Insulated Multi-Signature Scheme
Tiantian Xun · Journal of Qingdao University · 2013
A new scheme that simultaneously has the quality of strong key-insulated security and multi-signatures is proposed.The signatures in one time period are valid as long as one secret key of the signers is not exposed in this time period.At the same time,the proposed scheme proves to be security based on the difficulty of computational Diffie-Hellman problem in the standard model.
