RITM: Revocation in the Middle [PDF]

2016 IEEE 36th International Conference on Distributed Computing Systems (ICDCS), 2016
Although TLS is used on a daily basis by many critical applications, the public-key infrastructure that it relies on still lacks an adequate revocation mechanism. An ideal revocation mechanism should be inexpensive, efficient, secure, and privacy-preserving.
