What is Network Security? Definition, Threats & Protections

Network security creates shielded, monitored, and secure communications between users and assets. Despite the rapid evolution of what constitutes the users, assets, and connections, the fundamentals of networking security remain the same: block external threats, protect internal network communications, monitor the network for internal and external threats, and ensure that users only access authorized parts […]

Side-Channel Attack against CRYSTALS-Kyber

CRYSTALS-Kyber is one of the public-key algorithms currently recommended by NIST as part of its post-quantum cryptography standardization process.

Researchers have just published a side-channel attack—using power consumption—against an implementation of the algorithm that was supposed to be resistant against that sort of attack.

The algorithm is not “broken” or “cracked”—despite headlines to the contrary—this is just a side-channel attack. What makes this work really interesting is that the researchers used a machine-learning model to train the system to exploit the side channel…
