Do Internet, GSM, and wireless networks belong to the insecure communication channels?
Thursday, 22 May 2025 by Theresa Sittel
Internet, GSM, and wireless networks are all considered insecure communication channels from the perspective of classical and modern cryptography. To understand why this is the case, one must examine the inherent properties of these channels, the types of threats they face, and the security assumptions made in cryptographic protocol design. 1. Definition of Secure vs.

The Wi-Fi access points can be best compared to switches in wired networks?
Monday, 18 December 2023 by Acácio Pereira Oliveira
Wi-Fi access points and switches are both essential components in computer networks, but they serve different purposes and operate at different layers of the network architecture. While they share some similarities, it is important to understand their distinct functionalities and how they contribute to the overall network infrastructure. A switch is a networking device that
