Highly Controlled, Fine-grained Delegation of Signing Capabilities
Delegation of signing rights is a central problem in security. Whereas delegating by givingpower of attorney is well studied and digitally realized via delegatable anonymous credentials,directly delegating signing possibilities without the need for an external logic, can be done viamalleable signature schemes. However, the existing schemes do not allow for privacy preserving,fin...
متن کاملFine-Grained Data Security in Virtual Organizations
Controlling the access to data based on user credentials is a fundamental part of database management systems. In most cases, the level at which information is controlled extends only to a certain level of granularity. In some scenarios, however, there is a requirement to control access at a more granular way allowing the users to see only the data they are supposed to see in a database table. ...
متن کاملFine Grained Control of Security Capability and Forward Security in a Pairing Based Signature Scheme
Recently, Libert and Quisquater showed that the fast revocation method using a SEcurity Mediator(SEM) in a mRSA can be applied to the Boneh-Franklin identity based encryption and GDH signature scheme. In this paper we propose a mediated identity based signature(mIBS) scheme which applies the SEM architecture to an identity based signature. The use of a SEM offers a number of practical advantage...
متن کاملFine-grained integration of access control policies
Collaborative and distributed applications, such as dynamic coalitions and virtualized grid computing, often require integrating access control policies of collaborating parties. Such an integration must be able to support complex authorization specifications and the finegrained integration requirements that the various parties may have. In this paper, we introduce an algebra for fine-grained i...
متن کاملUltra-Fine Grained Dual-Phase Steels
This paper provides an overview on obtaining low-carbon ultra-fine grained dual-phase steels through rapid intercritical annealing of cold-rolled sheet as improved materials for automotive applications. A laboratory processing route was designed that involves cold-rolling of a tempered martensite structure followed by a second tempering step to produce a fine grained aggregate of ferrite and ca...
