This paper gives a new definition of Security, which takes causal information into account. The new definition can be used to determine the security of nondeterministic concurrent...
As a general design criterion, a symmetric key cipher should not be closed under functional composition due to the implications on the security of the cipher. However, there are s...
Several programming constructs have recently been proposed with the purpose of enabling the programmer to encode declassifying information flows within a program that complies wi...
We investigate the formal relationship between separability of processes and the types of non-interference properties they enjoy. Though intuitively appealing, separability – th...
Information dissemination is of vital importance in today's information-centric world. However, controlling the flow of information across multiple security domains is a probl...
