UK becomes first country to ban default bad passwords on IoT devices
Britain now has IoT hardware standards that ban weak or easily guessable default passwords such as “admin” or “12345." Manufacturers are also required to publish contact details so users can report bugs.

R5Detect: Detecting Control-Flow Attacks from Standard RISC-V Enclaves
Embedded and Internet-of-Things (IoT) devices are ubiquitous today, and the uprising of several botnets based on them (e.g., Mirai, Ripple20) raises issues about the security of such devices. Especially low-power devices often lack support for modern system security measures, such as stack integrity, Non-eXecutable bits or strong cryptography. In this work, we present R5Detect, a security monitoring software that detects and prevents control-flow attacks on unmodified RISC-V standard architec…

A unified Euler--Lagrange system for analyzing continuous-time accelerated gradient methods
This paper presents an Euler--Lagrange system for a continuous-time model of the accelerated gradient methods in smooth convex optimization and proposes an associated Lyapunov-function-based convergence analysis framework. Recently, ordinary differential equations (ODEs) with dumping terms have been developed to intuitively interpret the accelerated gradient methods, and the design of unified model describing the various individual ODE models have been examined. In existing reports, the Lagrang…
