Cryptographic measures in information hiding
Recent information hiding schemes are scrutinized in terms of their cryptographic performance. We establish conditions under which the key equivocation function is optimal for the...

Cryptographic Enforcement of Role-Based Access Control
Many cryptographic schemes have been designed to enforce information flow policies. However, enterprise security requirements are often better encoded, or can only be encoded, usin...

An elliptical cryptographic algorithm for RF wireless devices
In this paper, we propose a new asymmetric cryptographic algorithm (HOOD CRYPT) based on the Elliptical Curve Cryptographic approach. The algorithm describes how an orthogonal fre...

Heuristics for Improving Cryptographic Key Assignment in a Hierarchy
In hierarchical distributed systems, shared data access can be controlled by assigning user groups single cryptographic keys that allow high level users derive low level keys, but...
