Cruel Summer: hybrid signatures, Downfall, Zenbleed, 2G downgrades

The hosts discuss their summer vacation experiences and touch on topics like pixel attacks, 2G deprecation, and writing modem firmware. They explore vulnerabilities Zenbleed, Downfall, Spectre, and Meltdown, discussing technical details, risks, and potential exploitation. They also talk about software and firmware vulnerabilities, downgrade attacks, and crypto talks at conferences. The chapter covers lattice-based Kyber and dilithium schemes, the need to check old papers, and explore alternatives in cryptography. They discuss issues with authentic code, X-509, SSL slippery slope, and call for reviews.
