Abstract :
We improve the signcryption SCS2 proposed by Zheng Y to satisfy public verifiability and forward security simultaneously. Using this improved scheme, a new method of identifying cheaters in secret sharing schemes is proposed. With the method, a private channel is not necessary between the Dealer and each participant, and anyone can verify the authenticity of the share released by any participant during reconstructing the secret.
