Bailing Liu, Hongwei Lu, Yizhu Zhao, Feng Ge · 2010
Automated trust negotiation (ATN) is an approach that establishes mutual trust between strangers wishing to share resources or conduct business by gradually requesting and disclosing digitally signed credentials. When designing security schemes and systems in ATN, the negotiation efficiency, which is a desirable property, is not considered sufficiently. In this paper, a useful model of P. E. evaluation is proposed to enhance negotiation efficiency by improving the efficiency of security schemes used in ATN. The useful model of P. E. evaluation is responsible for choosing a most appropriate policy among several alternative policies that can advance a negotiation at the same time, which makes the negotiation more efficient.
