Detecting MITM attacks automatically - hard, but not impossible

2013-02-28 Thread John Nagle
The conventional wisdom is that it's not possible to detect MITM attacks other than by using some trusted path to validate the credentials from the other end. But that's not quite true. When an attacker decrypts with one key and re-encrypts with another, the encrypted bit stream changes. Both
