Realising a biometric identification scheme with the constraint of storing only encrypted data is an exciting challenge. Whereas a recent cryptographic primitive described by Bringer et al. and named Error-Tolerant Searchable Encryption achieves such a goal, the associated construction is not scalable to large databases. This paper shows how to move away from the model of Bringer et al., and proposes...
We improve the NP proof for the insecurity problem, partly motivated by an error in the NP proof of the influential paper “Protocol insecurity with a finite number of sessions and composed keys is NP-complete” by Rusinowitch and Turuani [1]. We enhance several different aspects of the proofs with a complete presentation, and we prove stronger results that fix the non-trivial error. Besides fixing...
In enterprise networks, the management of security policies and their configurations becoming increasingly difficult due to complex security constraints of the organizations. In such networks, the overall organizational security policy (global policy) is defined as a collection of rules for providing service accesses between various network zones. Often, the specification of the global policy is incomplete;...
