A new powerful covert-channel for the ARM Trustzone is being uncovered at #CARDIS22 Time's a Thief of Memory: Breaking Multi-tenant Isolation in TrustZones through Timing based Bidirectional Covert Channels presented by Nimish Mishra

Discussing security bounds on masked implementation in the new work proposed A Nearly Tight Proof of Duc et al.s Conjectured Security Bound for Masked Implementations, in the work by Loïc Masure, Olivier Rioul, François-Xavier Standaert

Final talk for this morning is Short-Iteration Constant-Time GCD and Modular Inversion by Yaoan Jin, Atsuko Miyaji, the code will be released on github.

Maria Eichlseder gives a tour de force today when explaining fault attacks on cryptographic implementations in her keynote at CARDIS Conference

The first talk this afternoon is Guarding the First Order: The Rise of AES Maskings, presented by Zhenda Zhang and co-authored by Amund Askeland, Siemen Dhooghe, Svetla Nikova, Vincent Rijmen. The talk presents three interesting new designs for masked AES;

Getting rid of the zero-operands makes for an efficient implementation, Rivain-Prouff on Steroids: Faster and Stronger Masking of the AES in the presentation given by Johann Groszschaedl, co-authored with Luan Cardoso dos Santos, Francois Gerard, Lorenzo Spignoli

The final talk of the day, shows how to implement masked AES without using registers. The secret is in using Muller-C elements, work by Mateus Simões, Lilian Bossuet, Nicolas Bruneau, Vincent Grosso, Patrick Haddad, Thomas Sarno

In the tast talk before the lunch, Luk Bettale presents the Security Assessment of NTRU Against Non-Profiled SCA, work done with Julien Eynard, Simon Montoya, Guénaël Renault, Rémi Strullu, the dataset and code will be available soon

Luk Bettale, is talking about the challenges of using of post-quantum protocols for banking applications, work he co-authored with Marco De Oliveira, Emmanuelle Dottax

Last but least, Corentin Verhamme, presents an in-depth side-channel analysis of the NIST lightweight candidates, see Analyzing the Leakage Resistance of the NIST’s Lightweight Crypto Competition’s Finalists, co-authored with Gaëtan Cassiers, François-Xavier Standaert

It was my privilege to introduce Dan Page as the keynote speaker today at CARDIS Conference where he talked about the role of ISA in designing secure crypto implementations. The slides will be online and I will for sure revisit them

Congratulations to Patrick Gersch, for winning the “Best Presentation” award, in the foto David Oswald is giving the award.
