Comments on a cryptographic key assignment scheme

چکیده
In this paper we analyse the security of a cryptographic key assignment scheme, recently proposed by Huang and Chang, that is designed to provide time-constrained hierarchical access control. We show that the new scheme has potential security vulnerabilities, which enable malicious users and attackers to violate the privacy of other users. keywords: Key assignment, Access control.

An Improvement of Novel Cryptographic Key Assignment Scheme for Dynamic Access Control in a Hierarchy
This letter presents a cryptographic key assignment scheme for dynamic access control in a hierarchy. A scheme for extending a previous cryptographic key assignment scheme to reduce the computation required for key generation and derivation algorithms is also proposed.
متن کاملA New Cryptographic Key Assignment Scheme using a One-way Hash Function
Access control in a hierarchy plays an important role in today’s communication networks. To guarantee the quality of communication services it is necessary to construct a low-computation dynamic access control scheme for the use to obtain the secure information. Therefore, we propose an efficient identity-based cryptographic key assignment scheme in which the cryptographic key of each user is c...
متن کاملCryptographic key assignment schemes for any access control policy
The access control problem deals with the management of sensitive information among a number of users who are classified according to their suitability in accessing the information in a computer system. The set of rules that specify the information flow between different user classes in the system defines an access control policy. Akl and Taylor first considered the access control problem in a ...
متن کاملA novel key management scheme for heterogeneous sensor networks based on the position of nodes
Wireless sensor networks (WSNs) have many applications in the areas of commercial, military and environmental requirements. Regarding the deployment of low cost sensor nodes with restricted energy resources, these networks face a lot of security challenges. A basic approach for preparing a secure wireless communication in WSNs, is to propose an efficient cryptographic key management protocol be...
متن کاملA Cryptographic Key Assignment Scheme with Adaptable Time- token Constraint in a Hierarchy
A scheme, which uses flexible cryptographic key management upon adaptable time-token constraint for a user hierarchy access control (UHAC) scheme, is proposed in this paper. For adapting the changeability in a UHAC system, we propose a technique of assigning independent time-token which is distributed by a trusted agency server to reply an authorized user for once secure access request. The key...
