Administration in Role - Based Security Systems 1

چکیده
This paper examines the concept of role-based protection and, in particular, role organization. From basic role relationships, a model for role organization is developed. The role graph model, its operator semantics based on graph theory and algorithms for role administration are proposed. The role graph model, in our view, presents a very generalized form of role organization for access rights administration. It is shown how the model simulates other organizational structures such as hierarchies [TDH92] and privilege graphs [Bal90].

متن کاملOn the design and security of a lattice-based threshold secret sharing scheme
In this paper, we introduce a method of threshold secret sharing scheme (TSSS) in which secret reconstruction is based on Babai's nearest plane algorithm. In order to supply secure public channels for transmitting shares to parties, we need to ensure that there are no quantum threats to these channels. A solution to this problem can be utilization of lattice-based cryptosystems for these channe...
