Formal Verification of Probing Security Via Conditional Independence

Side-channel attacks are a major threat to the security of cryptosystems. Masking is a widely used countermeasure against such attacks, but proving the security of masked algorithms is error-prone without formal verification. In this work, we propose a novel approach to formal verification of...

Xen 安全漏洞

Xen is an open source virtual machine monitor product from Xen Open Source. The product enables different and incompatible operating systems to run on the same computer and supports runtime migration to ensure uptime and avoid downtime. A security vulnerability exists in Xen that stems from...

Secure Parsing and Serializing with Separation Logic Applied to CBOR, CDDL, and COSE

Incorrect handling of security-critical data formats, particularly in low-level languages, are the root cause of many security vulnerabilities. Provably correct parsing and serialization tools that target languages like C can help. Towards this end, we present PulseParse, a library of verified...
