Cryptanalysis of A General Secret Sharing Scheme
Hua Xu · 2008
The paper analyzes a general secret sharing scheme(LL scheme).The result shows that the LL scheme do not provide the function of cheat-proof,because the malicious share holder can easily provide false information so that other honest participants will be misled to believe that the recovered secret is correct.Furthermore,a modified scheme based on discrete logarithm is put forward,which can overcome the potential security hazard,and remain the attractive properties of LL scheme at the same time.
