We propose a new password-based 3-party protocol with a formal security proof in the standard model. Under reasonable assumptions we show that our new protocol is more efficient t...
We present the first machine-checked correctness proof for information flow control (IFC) based on program dependence graphs (PDGs). IFC based on slicing and PDGs is flow-sensi...
The notion of Zero Knowledge Proofs (of knowledge) [ZKP] is central to cryptography; it provides a set of security properties that proved indispensable in concrete protocol design...
Abstract. In this paper we report on the performance of the RSA variants of Brands protocols for zero-knowledge proof and restrictive blinded issuing [1]. The performance is relati...
Abstract. Cloud computing is a new computing paradigm that is gaining increased popularity. More and more sensitive user data are stored in the cloud. The privacy of users’ acces...
