External entropy supply for IoT devices employing a RISC-V Trusted Execution Environment
Arttu Paju, Juha Nurmi, Alejandro Cabrera Aldaya +4
Entropy--a measure of randomness--is compulsory for the generation of secure cryptographic keys; however, Internet of Things (IoT) devices that are small or constrained often strug…
HyperDegrade: From GHz to MHz Effective CPU Frequencies
Alejandro Cabrera Aldaya, Billy Bob Brumley
Performance degradation techniques are an important complement to side-channel attacks. In this work, we propose HyperDegrade -- a combination of previous approaches and the use of…
Déjà Vu: Side-Channel Analysis of Mozilla's NSS
Sohaib ul Hassan, Iaroslav Gridin, Ignacio M. Delgado-Lozano +4
Recent work on Side Channel Analysis (SCA) targets old, well-known vulnerabilities, even previously exploited, reported, and patched in high-profile cryptography libraries. Neverth…
Online Template Attacks: Revisited
Alejandro Cabrera Aldaya, Billy Bob Brumley
An online template attack (OTA) is a powerful technique previously used to attack elliptic curve scalar multiplication algorithms. This attack has only been analyzed in the realm o…
Certified Side Channels
Cesar Pereida García, Sohaib ul Hassan, Nicola Tuveri +3
We demonstrate that the format in which private keys are persisted impacts Side Channel Analysis (SCA) security. Surveying several widely deployed software libraries, we investigat…
