Splitting the HTTPS Stream to Attack Secure Web Connections

Folks,

IEEE Security and Privacy published an article that my group and I wrote some months ago, it's titled : Splitting the HTTPS Stream to Attack Secure Web Connections. You can find it here, check it out !



Abstract:
The HTTPS protocol is commonly adopted to secure connections to websites, both to guarantee the server's authenticity and to protect the privacy of transmitted data. However, the computational load associated with the protocol's key exchange and encryption/decryption activities isn't negligible. Many trafficked websites must avoid using HTTPS for most of their pages, typically restricting its usage only to encrypting sensitive user data. This article illustrates how this common practice significantly reduces the possibility of detecting manipulations of the data stream by the client, thus exposing the user to potential man-in-the-middle attacks.
