New TCG guidance gives buyers a way to test PQC-ready TPM claims

Help Net Security

The Trusted Computing Group (TCG) has released new guidelines for Trusted Platform Modules (TPMs), which are essential components that secure a device's cryptographic keys and firmware integrity. These guidelines specifically address how TPMs can be deemed quantum-safe, a growing concern as quantum computing technology advances. Now, buyers can request proof from vendors that their TPMs meet these new standards, ensuring they are prepared for future quantum threats. This is significant for companies looking to protect their data from potential quantum attacks, as it provides a way to verify the security claims made by manufacturers. The move aims to enhance the overall security landscape as businesses transition to quantum-resistant technology.

Developer alleges Alibaba uses audio fingerprinting for web tracking

SCM feed for Latest

Matt Callaghan, a software engineer, has raised concerns that Alibaba's website may be using audio fingerprinting techniques for tracking users. He found that the site employs obfuscated audio scripts that create a waveform and analyze its output, which could allow the company to monitor user behavior in a way that bypasses traditional tracking methods. This discovery raises significant privacy issues, as it suggests that users may be unwittingly tracked through audio signals emitted from their devices. The implications are serious, especially for individuals who value their privacy online. The use of such techniques could lead to increased scrutiny from regulators and may prompt users to reconsider their interactions with the site.
