Trusted Verifiable Multisecret Sharing Scheme Based on(t,n) Threshold
Shiyang Zhou · Journal of Chinese Computer Systems · 2008
A new trusted verifiable multi-secret sharing(TVMSS) scheme which is based on the(t,n) threshold is proposed.In the scheme,multiple secrets can be shared simultaneously by the system.The dealer is able to split a system secret into n different reusable verifiable secure sub-secrets,and distribute the sub-secrets to the n participants respectively.Participant can verify secure sub-secret via public message.The proposed scheme provides efficient solutions against potential cheating done by either the dealer or a participant,hackers' tampering of public message,and malicious participant's forging of all or some secrets of the system.Through strict verifying process,every secret reconstructed by participant is reliable.
