In this paper we present an implementation of an algorithm for creating a secure sketch for the set difference as defined in [1]. This sketch is a short, efficiently computable description of a set such that, given a second set that differs only in a small percentage of elements, the original can be reconstructed. However, this sketch is secure in the sense that in the absence of such a similar...

A wide variety of powerful cryptographic tools have been built using RSA, Diffie-Hellman, and other similar assumptions as their basis. Computational security has been achieved relative to complexity assumptions about the computational difficulty of a variety of number theoretic problems. However, these problems are closely related, and it is likely that if any one of them turns out to be effic...

Secure set intersection protocols are the core building block for a manifold of privacy-preserving applications. In a recent work, Hazay and Lindell (ACM CCS 2008) introduced the idea of using trusted hardware tokens for the set intersection problem, devising protocols which improve over previous (in the standard model of two-party computation) protocols in terms of efficiency and secure compos...

A secure sketch is a set of published data that can help to recover the original biometric data after they are corrupted by permissible noises, and by itself does not reveal much information about the original. Several constructions have been proposed for different metrics, and in particular, set difference. We observe that in many promising applications, set difference alone is insufficient to...
