%X Automated trust negotiation is an approach to build trust relationship between strangers by disclosing attribute credentials alternately. The attributes owned by principles are always relevant each other, so disclosing some attributes maybe induce leakage of sensitive information, namely inference attack. We give the definition and partial order of sensitivity intensity of private attribute, then an abstract automated trust negotiation model is proposed, which depicts relevancy not only between principles and attributes, but also between policies and attributes. As a result, several inference attacks in automated trust negotiation are discussed, then defense scheme and security analysis are presented.
