CIKM 2016: Efficient Orthogonal Non-negative Matrix Factorization over Stiefel Manifold

This work has been accepted as a full paper by CIKM 2016. Non-negative Matrix Factorization is an important mathematical tool for various data mining applications. In this paper, CDIT researchers develop an efficient orthogonal non-negative matrix factorization over Stiefel manifold, which significantly outperforms other state-of-the-art algorithms in terms of convergence speed and clustering performance. Efficient Orthogonal Non-negative Matrix Factorization over […]

ACSAC 2016: Amplifying Side Channels Through Performance Degradation

In this work, accepted to ACSAC 2016, we show that an adversary can amplify a side channel leakage from a victim by slowing the victim down. We apply the technique against a victim that uses the Bitcoin elliptic curve and show that we need to observe only 6 signatures to completely break the private key.  The […]

Yuval Yarom to deliver a keynote talk at PROOFS 2016

Yuval Yarom has been invited to present a keynote talk at PROOFS 2016. PROOFS is a security workshop focusing on Security Proofs for Embedded Systems. Title: Thwarting cache-based side-channel attacks Abstract: Cache-based side-channel attacks leak sensitive information through a shared cache. The attacker exploits contention on the cache to trace the victim’s access to memory. These traces […]
