Abstract: 

Motivated by the revelations of Edward Snowden, post-Snowden cryptography has become a prominent research direction in recent years. In Eurocrypt 2015, Mironov and Stephens-Davidowitz proposed a novel concept named Cryptographic Reverse Firewall (CRF) which can resist exfiltration of secret information from an arbitrarily compromised machine. In this presentation, we will review some recent development of CRFs for different cryptographic protocols, including those for Authenticated Key Exchange (Dodies et al. CRYPTO’16), Oblivious Signature Based Envelope and Oblivious Transfer (Chen et al. ASIACRYPT’16). Some open problems and possible future research directions will also be discussed.

Dr. Guomin Yang is a DECRA Research Fellow at the School of Computing and Information Technology, University of Wollongong (UOW), Australia. He was admitted to the Mathematics Department of Fudan University in 1999, and moved to City University of Hong Kong in 2000 after being awarded the Hong Kong Jockey Club Scholarship. He received the Bachelor, Master and PhD degrees in Computer Science from City University of Hong Kong in 2004, 2006 and 2009, respectively. Before joining UOW in 2012, he was a Research Scientist at the Temasek Laboratories, National University of Singapore (NUS). Dr. Yang’s research interests include applied cryptography and network security. He has published over 90 research papers that have appeared at many respected venues such as ACM/IEEE Transactions, CRYPTO, ASIACRYPT, PKC, CT-RSA, etc. In 2015, he received the Australian Research Council Discovery Early Career Researcher Award.
