- The paper "MEGA – Malleable Encryption Gone Awry” received a external pagedistinguished paper award at the 2023 IEEE Symposium on Security and Privacycall_made for the work of Matilda Backendal, former ETH Master student and current UCSD PhD student Miro Haller, and Kenny Paterson. In this paper the team took a close look at security in the MEGA system, one of the largest consumer-facing cloud storage systems with more than 250 million users and more than 1000 Petabytes of stored data. The team uncovered five significant cryptographic vulnerabilities in the MEGA system.
- The paper "Post-Quantum Anonymity of Kyber" by group member Varun Maram and collaborator Keita Xagawa from NTT Social Informatics Laboratories, Japan, received the external pagebest paper award at the PKC 2023 conferencecall_made. In this work, Varun and Keita provide concrete proofs of (tight) IND-CCA security and anonymity of the new NIST PQC standard Kyber in a post-quantum setting, thereby resolving issues identified by prior works.
