Abstract: | Until now, there are numerous protocols that can achieve privacy-preserving trust negotiation between two parties involved,
but there is no effective privacy-preserving trust negotiation schemes proposed between multi-users. In this paper, a privacy-preserving
trust negotiation scheme with multi-parties is proposed, which can protect their credentials and access control policies during
the procedure for establishing the trust between multi-strangers, and its privacy-preserving ability also is proved. These
works extend the trust negotiation mechanism to multi-users, which can be thought as a substantial extension of the state-of-the-art
in privacy-preserving trust negotiations between two parties involved
