WebBringing kleptography to real-world TLS. Kleptography is a study of stealing information securely and subliminally from black-box cryptographic devices. The stolen … During the TLS handshake, assuming no pre-shared key is involved and a new session is to be established, all traffic keys are derived from a pre-master secret and publicly available values. Thus, for an attacker, it suffices to obtain the pre-master secret to decrypt whole session. Additionally, the pre-master secret can be … See more Under the following assumptions, our proposal is a SETUP: 1. A random oracle is used to generate the values k and to sanitize the values … See more The reader can easily verify that properties 1–3 of SETUP hold for our backdoor. To prove property 4, we show how the attacker can obtain the seed S by eavesdropping on … See more
