Implementation and Transition to Post-Quantum Cryptography of the Minimal IKE Protocol

This paper concerns the Minimal Internet Key Exchange IKE protocol, which has received little attention to date, despite its potential to make the best-known IKE protocol sufficiently lightweight to be also applied in contexts where it is currently prohibitive, due to its large footprint. First, ...

The vulnerability of the tmpserver module in TP-Link Archer AX53 microprogramming software allows attackers to carry out “man-in-the-middle” attacks.

The vulnerability of the tmpserver module in TP-Link Archer AX53 microprogramming software relates to the exchange of keys without authentication of the target device. Exploiting this vulnerability allows a malicious actor to carry out “man-in-the-middle” attacks remotely...
