Threshold Signature Scheme Based on Modular Secret Sharing
Qi You Xie, Zhonghua Shen, Xiuyuan Yu · 2008
How to overcome the conspiracy attacks on threshold signature is very important problem. To resist the conspiracy attacks, many threshold signature schemes are based on the complicated variants of the Lagrange interpolation sharing scheme. Based on Asmuth-Bloom modular secret sharing, a new threshold signature scheme is proposed. The scheme can resist the conspiracy attacks, and is more efficient under pre-computation.
