Prof. Dr. Mark Manulis joined as Full Professor the Research Institute CODE and the Department of Computer Science at the Universität der Bundeswehr München on March 1, 2022 and gave an interview where he talks about his appointment and future plans.

PACY lab has three open positions for PhD students or post-docs to work on exciting research challenges. Please check our Vacancies page for more information.

This week Prof. Manulis attended the 20th International Conference on Applied Cryptography and Network Security (ACNS) in Rome, Italy. The conference programme featured his joint work on "Revocable Hierarchical Attribute-based Signatures from Lattices" with Daniel Gardham from the Surrey Centre for Cyber Security in the UK, who gave the presentation. Hierarchical attribute-based signatures can be used to realise privacy-preserving public key infrastractures and this paper is the first to realise the required functionality using lattices that enable post-quantum security.

This week our paper "Unlinkable Delegation of WebAuthn Credentials" was presented at the 27th European Symposium on Research in Computer Security (ESORICS 2022) in Copenhagen, Denmark. The talk was delivered by Nick Frymann, an external PhD student of Prof. Manulis at the University of Surrey, UK. This paper builds on our earlier work on Asynchronous Remote Key Generation (ARKG), a new primitive for generation of cryptographic key pairs, developed in 2020 in collaboration with Yubico. We showed how ARKG can be used to enable delegation of credentials for WebAuthn protected accounts by account owners to their proxies in a way that is controllable and preserves the original security and privacy properties of the WebAuthn standard. WebAuthn is a new standard for web authentication that is expected to replace passwords and other insecure authentication methods by adopting digital signatures and security keys.
