Resaerch of (t,n) secret sharing scheme against active cheating
Jianghong Han · Journal of Zhejiang University(Science Edition) · 2007
In existing encryption schemes with(t,n) secret shared control,n verifiers have to broadcast the shadows of message to each other in order to reconstruct the message.A new(t,n) secret sharing scheme is proposed,in which the verifiers don't need to broadcast the shadows of message to each other.Thus,this scheme can achieve higher security and reduce the traffic of network.Besides,the scheme provides the function of key and message authentication.It can not only prevent forging attacks,but also find the active cheating of any verifier.
