This work was done by Alex Balducci and Andy Lee. The main document is gkepnormxormsimplifiedwriteup.txt. It contains references to the...

Beyond the Finite Variant Property: Extending Symbolic Diffie-Hellman Group Models (Extended Version)

Diffie-Hellman groups are commonly used in cryptographic protocols. While most state-of-the-art, symbolic protocol verifiers support them to some degree, they do not support all mathematical operations possible in these groups. In particular, they lack support for exponent addition, as these tool...

One for All: Formally Verifying Protocols Which Use Aggregate Signatures (Extended Version)

Aggregate signatures are digital signatures that compress multiple signatures from different parties into a single signature, thereby reducing storage and bandwidth requirements. BLS aggregate signatures are a popular kind of aggregate signature, deployed by Ethereum, Dfinity, and Cloudflare...
