Abstract: A new secret sharing scheme is constructed based on the tree structure and the mechanism of mobile agent.The shareholders are grouped with their levels and each group can renew the shared secret with the shares they holds.After each group renews their secret,the news become a share of the apper level,and a new secret sharing process comes into being,hence a tree structure is formed by this process.The mechanism of mobile agent makes the tree structure dynamic,and the shareholder doesn't know exactly which group he is subjected to.So the cahoots are avoided to a great extent and a more secure multi-stage secret sharing is realized.
