Authentication in Quantum Networks

In this review, we survey the cryptographic task of authentication from the perspective of quantum communication. We review three main flavours of authentication that are often conflated in the literature: authentication of classical messages, authentication of quantum messages, and entity...

Key Exchange without Entity Authentication

Overview Affected versions of this package are vulnerable to Key Exchange without Entity Authentication due to the SSH client not verifying remote host keys for git+ssh:// connections. An attacker can intercept and compromise mirrored repositories by performing man-in-the-middle attacks...
