Silent Bugs Matter: A Study of Compiler-Introduced Security Bugs

Mathias Josef Payer, Jianhao Xu

Compilers assure that any produced optimized code is semantically equivalent to the original code. However, even "correct" compilers may introduce security bugs as security properties go beyond translation correctness. Security bugs introduced by such corr ...

Security Measures for Grids Against Rank-1 Undetectable Time-Synchronization Attacks

Jean-Yves Le Boudec, Marguerite Marie Nathalie Delcourt

Time-synchronization attacks on phasor measurement units (PMUs) pose a real threat to smart grids; it was shown that they are feasible in practice and that they can have a nonnegligible negative impact on state estimation, without triggering the bad data d ...

Subdomain and Access Pattern Privacy Trading off Confidentiality and Performance

Bin Lu, Thomas Locher, Matus Harvan

Homomorphic encryption and secure multi-party computation enable computations on encrypted data. However, both techniques suffer from a large performance overhead. While advances in algorithms might reduce the overhead, we show that achieving perfect (or e ...

The Bussard-Bagga and Other Distance-Bounding Protocols under Attacks

Serge Vaudenay, Aikaterini Mitrokotsa, Asli Bay, Ioana Cristina Carlson, Iosif-Daniel Spulber

The communication between an honest prover and an honest verifier can be intercepted by a malicious man-in-the-middle (MiM), without the legitimate interlocutors noticing the intrusion. The attacker can simply relay messages from one party to another, even ...

Cryptographic Hash Functions in Groups and Provable Properties

Juraj Sarinay

We consider several "provably secure" hash functions that compute simple sums in a well chosen group (G,*). Security properties of such functions provably translate in a natural way to computational problems in G that are simple to define and possibly also ...
