New approach to practical leakage-resilient public-key cryptography

Autor: Chakraborty Suvradip, Alawatugoda Janaka, Rangan Chandrasekaran Pandu

Publikováno v: Journal of Mathematical Cryptology, Vol 14, Iss 1, Pp 172-201 (2020)

We present a new approach to construct several leakage-resilient cryptographic primitives, including leakage-resilient public-key encryption (PKE) schemes, authenticated key exchange (AKE) protocols and low-latency key exchange (LLKE) protocols. To t

Efficiently Testable Circuits

Autor: Baig, Mirza Ahad, Chakraborty, Suvradip, Dziembowski, Stefan, Gałązka, Małgorzata, Lizurej, Tomasz, Pietrzak, Krzysztof

Publikováno v: Leibniz International Proceedings in Informatics (LIPIcs), 251
14th Innovations in Theoretical Computer Science Conference (ITCS 2023)

In this work, we put forward the notion of “efficiently testable circuits” and provide circuit compilers that transform any circuit into an efficiently testable one. Informally, a circuit is testable if one can detect tampering with the circuit b

Subversion attacks undermine security of cryptographic protocols by replacing a legitimate honest party’s implementation with one that leaks information in an undetectable manner. An important limitation of all currently known techniques for design

Reverse firewalls were introduced at Eurocrypt 2015 by Miro-nov and Stephens-Davidowitz, as a method for protecting cryptographic protocols against attacks on the devices of the honest parties. In a nutshell: a reverse firewall is placed outside of a
