Abstract: Trust management can be used to deal with a number of security issues in virtual networks. In internet communications, efficient secure trust negotiation between virtual individuals/organisations is very important as it can achieve resource sharing, collaborative computing and communication security. This investigation aims to strengthen the efficiency and security of trust negotiation by using: 1) a more advanced negotiation strategy to facilitate negotiation; 2) more precise principles to attain better access control policy assignments; 3) iterative computation and a cache mechanism to further enhance negotiation efficiency. Experimental evaluation is conducted to compare the performance of our strategy and related strategies under several performance measures of interest. The result shows that our new strategy outperforms other strategies in most situations as it obtains a well-balanced trade-off between the efficiency and security of trust negotiation.
Keywords: network security; automated trust negotiation; access control policies; credentials; negotiation strategies; virtual networks; experimental evaluation; trust management; negotiation efficiency.
