OBJECTIVES In this article we present grids as an architecture for medical image processing and health-care networks. We argue that confidential patient data should not be stored unprotected on a grid and explain why access control systems alone do not offer sufficient protection. The objective of our work is to propose a method that complements access control systems on a grid architecture and...

Secret sharing schemes are widely used now a days in various applications, which need more security, trust and reliability. In secret sharing scheme, the secret is divided among the participants and only authorized set of participants can recover the secret by combining their shares. The authorized set of participants are called access structure of the scheme. In Multi-Secret Sharing Scheme (MS...

Femtocells can be employed in cellular systems to enhance the indoor coverage, especially in the areas with high capacity growing demands and high traffic rates. In this paper, we propose an efficient resource utilization protocol, named as shared access protocol (SAP), to enable the unauthorized macrocell user equipment to communicate with partially closed-access femtocell base station to impr...

Fine-grained access control for relational data defines user authorizations at the tuple level. Role Based Access Control (RBAC) has been proposed for relational data where roles are allowed access to tuples based on the authorized view defined by a selection predicate. During the last few years, extensive research has been conducted in the area of role en­ gineering. The existing approaches fo...

Systems that are used to process or handle classified or sensitive information must assure individual accountability whenever either a mandatory or discretionary security policy is invoked. Furthermore, to assure accountability the capability must exist for an authorized and competent agent to access and evaluate accountability information by a secure means, within a reasonable amount of time a...

A scheme for general group oriented ID-based cryptosystems is proposed. This scheme allows an authorized subset in the general access structure to cooperatively decrypt the ciphertext of a message. It is constructed using bi-linear pairings. Its security is based on the intractability of the computational bilinear Diffie-Hellman problem. The scheme possesses chosen-plaintext security in the ran...
