• Verifiable secret sharing scheme

A verifiable secret sharing scheme based IBE is proposed. In the scheme, the shared secret is the private key which extracted by IBE algorithm and every participator can verify the shares conveniently by the public information. A formal proof of semantic security of the scheme is provided in the random oracle model. The theoretical analysis indicates that the scheme can detect cheatings from both inside and outside attacker. The simulation results demonstrate that the proposed scheme has remarkable performance in both computation and communication cost.
