CVE-2026-71887 OpenPGP data signature accepted from a signing subkey without cross-certification

In Bouncy Castle for Java before 1.86, the high-level OpenPGP API accepted a data signature made by a signing subkey whose Subkey Binding signature carried no embedded Primary Key Binding cross-certification signature, in the case where that binding omits a Key Flags subpacket. RFC 9580 sec...

On the Construction of Trapdoor Claw-Free Functions with Certifiable Key

Trapdoor claw-free functions TCFs underpin much of classical-quantum cryptographic interaction, yet every TCF-based protocol states its guarantees relative to an honestly generated key. We give a family-agnostic abstraction of key certification for noisy TCF constructions, built on two notions: a...

Post-Hoc Trajectory-Risk Certification for Modular LLM-Based Security Agents

Autonomous security agents operate as staged pipelines, such as classifying network traffic and then attributing attacks to a specific technique. Split conformal prediction gives each stage finite-sample coverage, but deployment requires a trajectory-level guarantee across the full chain. These...
