Instance-oriented delegation: A solution for providing security to Grid-based mobile agent middleware

New challenges are introduced when people try to build a general-purpose mobile agent middleware in Grid envi- ronment. In this paper, an instance-oriented security mechanism is proposed to deal with possible security threats in such mobile agent systems. The current security support in Grid Security Infrastructure (GSI) requires the users to delegate their privileges to certain hosts. This host-oriented solution is insecure and inflexible towards mobile agent applications because it cannot prevent delegation abuse and control well the diffusion of damage. Our proposed solution introduces security instance, which is an en- capsulation of one set of authorizations and their validity specifications with respect to the agent’s specific code segments, or even the states and requests. Applications can establish and configure their security framework flexibly on the same platform, through defining instances and operations according to their own logic. Mechanisms are provided to allow users delegating their identity to these instances instead of certain hosts. By adopting this instance-oriented security mechanism, a Grid-based general-purpose MA middleware, Everest, is developed to enhance Globus Toolkit’s security support for mobile agent applications.

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.

Identity-based proxy multi-signature applicable to secure E-transaction delegations

To enhance the robustness of a proxy multi-signature scheme and improve its efficiency, a novel proxy signature paradigm is proposed referred to as In this paradigm, multiple proxy signer candidates identity-based proxy multi-signature （IBPMS）. are employed to play a role of the single proxy signer in the existing model. A provably secure IBPMS scheme is presented which requires only one round broadcast operation. Performance analysis demonstrates that the new scheme outperforms the existing multi-signature schemes in robustness and communication. These properties are rendered to our IBPMS scheme as a more practical solution to secure e-transaction delegation applications of proxy signatures.

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.

Personal Delegation by Persona Creation

There are many business needs for implementing delegation in IT （Information Technology） systems. However, existing approaches to delegation in IT systems are limited in their usability, flexibility, and capability to implement least privilege. The result is that delegation is either not implemented or is implemented informally （e.g., by sharing credentials [passwords or hardware tokens] between users）, resulting in serious security concerns and a lack of accountability. This paper describes a methodology for delegation based on the persona concept. A persona is a special category of user that embodies only delegated privileges, and which is explicitly assumed only after the ＂real＂ human user taking on that persona explicitly chooses it, This paper describes the persona delegation framework in the context of a large enclave-based architecture currently being implemented by a major enterprise. The creation of a persona solves a lot of downstream problems by allowing the persona to be treated like any other entity in the system. That is, identity, authentication, authorization, and other security processes already know how to handle an entity of this type. Benefits of the framework include increased flexibility to handle a number of different delegation business scenarios, decreased complexity of the solution, and greater accountability with only a modest amount of additional infrastructure required.
