The weak points of several secret sharing schemes is analyzed and a better algorithm of dynamic secret sharing scheme based on hash function is proposed.It has the following properties: The system can renew system secrets without renewing the shadows of the participants;When some participants' shadows are revealed,they don't threaten the others;A new shadow is generated for a new participant without any effect on the others;The shadows are reused for many times;Efficiently guard against cheating among participants.It is simulated on the computer and generated some experiment datum.Finally,the scheme's performance is analyzed through the datum.
