Enhanced Delegation Based Authentication Protocol for Secure Roaming Service with Synchronization

Portable communication systems can provide mobile users with global roaming services. Recently, Youn and Lim proposed a delegation-based authentication protocol which achieves unlinkability for secure roaming services. This paper indicates that there are two drawbacks in Youn and Lim＇s protocol： 1） the synchronization problem will lead to a fail in on-line authentication; and 2） the exhaustive search puts a heavy burden on the off-line authentication process. Moreover, based on Youn and Lim＇s protocol, a remedy is proposed to address these problems. It is worthwhile to note that the proposed remedy not only keeps the original advantages but also enhances the security and performance.

Using Hash Tree for Delegation Revocation in Grids

Grid security infrastructure （GSI） provides the security in grids by using proxy certificates to delegate the work of authentication. At present, revocation proxy certificate has two kinds of methods, one is using certificate revocation list （CRL） and the other is giving the certificate a short period of validity. However, when a lot of certifications are revoked, CRL will be the burden in the system. If the certificate has a short period of validity, entities should be often updating the certificate. In this paper, we propose a scheme for proxy certificate revocation using hash tree. Our scheme only needs hash value comparisons to achieve the purpose of certificate revocation. Previous two methods have to wait the expiration of the certificate. Therefore, our scheme is more flexible than previous methods.

The Delegation Led by LI Xin-ya Attending the 67th World Foundry Congress

Invited by Mr. Matthew Poole, Chairman of the Organization Committee of the 67th World Foundry Congress, the delegation of Foundry Institution of Chinese Mechanical Engineering Society (FICMES) led by LI Xin-ya, President of China Academy of Machinery Science and Technology, more recently attended the 67th World Foundry Congress, and visited the Royal Institute of Technology, Sweden; LOCOMO Cast Steel Company, Metso Corporation, Finland; Imperial College, London, United Kingdom; and Brunel University, United Kingdom. During the period of the Congress and in the course of visiting, the delegation had deeply technical exchanges with the organizations mentioned above in the fields of such technologies as numerical simulation and design of foundry technical processes, special materials and advanced casting technology for hydraulic turbines and steam turbines, dual-phase steels casting, nuclear shielding materials manufacturing, rheology and semi-solid casting technology, design and development of medium-frequency induction heating furnaces and so on. Both of them are on the chance of cooperation. The visiting of the delegation is quite successful. The 69th World Foundry Congress has been determined by World Foundry Organization to be held in China and it will be organized by Foundry Institution of Chinese Mechanical Engineering Society and China Academy of Machinery Science and Technology. The World Foundry Congress to be held in China will play the active role in facilitating the Chinese foundrymen to further understand and master the advanced foundry technologies in the world and promoting the digitalization, informatization and greening development of China?蒺s foundry technology.

A Collusion-Resistant Distributed Agent-Based Signature Delegation (CDASD) Protocol for E-Commerce Applications

Mobile agent technology is promising for e-commerce and distributed computing applications due to its properties of mobility and autonomy. One of the most security-sensitive tasks a mobile agent is expected to perform is signing digital signatures on a remote untrustworthy service host that is beyond the control of the agent host. This service host may treat the mobile agents unfairly, i.e. according to its’ own benefit rather than to their time of arrival. In this research, we present a novel protocol, called Collusion-Resistant Distributed Agent-based Signature Delegation (CDASD) protocol, to allow an agent host to delegate its signing power to an anonymous mobile agent in such a way that the mobile agent does not reveal any information about its host’s identity and, at the same time, can be authenticated by the service host, hence, ensuring fairness of service provision. The protocol introduces a verification server to verify the signature generated by the mobile agent in such a way that even if colluding with the service host, both parties will not get more information than what they already have. The protocol incorporates three methods: Agent Signature Key Generation method, Agent Signature Generation method, Agent Signature Verification method. The most notable feature of the protocol is that, in addition to allowing secure and anonymous signature delegation, it enables tracking of malicious mobile agents when a service host is attacked. The security properties of the proposed protocol are analyzed, and the protocol is compared with the most related work.
