摘要: The revelations of Edward Snowden in 2013 has attracted worldwide attention. It is shown that the computer machine could be compromised before delivered to the customer and the implemented cryptographic protocol may be even subverted and thus insecure as thought. Since then, 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 talk, I will firstly present two examples of cryptographic protocol subversion attacks and then introduce our recent progress on this line of research and show how to generically construct CRFs for several widely used cryptographic protocols including message-transmission protocol, oblivious signature-based envelope and oblivious transfer. This work has been published in ASIACRYPT 2016.
