Communication security is about a full security system that ensures the five main requirements of information security "confidentiality, integrity, availability, authenticity, and non-repudiation" during the whole transmission process from the "sender" to the "receiver" via technical, management, and institutional means. It is the prevention of information theft, tampering, interception, forgery, and damage as well as the provision of stable communication networks and devices operation. It is the core that supports the security of personal privacy, enterprise data, and national critical information infrastructure in the digital era by "covering the entire link of information transmission, all levels of communication networks, and all types of terminal devices".
To maintain communication security, the implementation of an integrated three-in-one system is a prerequisite, which involves "technical protection as the core, management measures as the guarantee, and institutional standards as the basis". This system spans the entire "terminal-network-cloud-data" chain and, in detail, comprises four key protection aspects:
Encryption Technology: The main instrument to secure "confidentiality" and "integrity" of information.
Identity Authentication and Access Control: Provide "authenticity" and "authorized access".
Network Protection Technology: Ensures the safety of "transmission links" and "network devices".
Terminal Security Protection: Helps to "starting and ending points of information" be more secure.
Communication frontiers have become more intricate with the advancement of new technologies like 5G, the Internet of Things (IoT), artificial intelligence (AI), and the metaverse. While communication security is confronting fresh issues, it has also facilitated novel protection trends:
1. IoT Communication Security: Addressing Security Pain Points of "Massive Devices"
The proliferation of IoT devices (e.g., smart home appliances, industrial sensors, and smart electricity meters) is a significant factor (by 2025, it is anticipated to exceed 75 billion globally). The majority of these devices are "low-computing-power and low-power-consumption" machines, which makes it hard for the traditional protection technologies to be compatible. Some of the major trends are:
Lightweight Encryption Technology: Creating "lightweight national cryptographic algorithms" that can be implemented on IoT devices (for example, a lightweight version of SM4). The new method ensures security while lessening the device's computing power and energy consumption.
Unified Device Identity Management: Building "an IoT device identity authentication platform" to provide each device with a unique "digital identity" (for example, blockchain-based device identity), thus, eliminating the possibility of device forgery or unauthorized access.
Edge Computing Collaborative Protection: Installing security protection features (for example, intrusion detection and data encryption) in IoT edge nodes (for example, edge gateways) to physically handle device security threats, thereby, decreasing the pressure on the core network.
2. 5G Communication Security: Responding to Security Challenges of "New Scenarios and New Architectures"
The features of 5G, such as "network slicing", "edge computing", and "massive connectivity", are the main causes of new communication security risks (e.g., network slice attacks and edge node intrusions). Some of the important movements are:
Network Slice Security Isolation: Creating "inter-slice security isolation mechanism" for 5G slices in diverse scenarios (e.g., industrial slices, transportation slices, and public slices) to stop the attack province from reaching the rest of slices.
Edge Node Security Hardening: Implementation of "edge security gateways" at edge computing nodes to attain "localized data encryption processing". Besides, the access of edge nodes is monitored to check the behavior of the visitor and to prevent unauthorized access.
5G Endogenous Security: The move from "passive protection" to "active defense" is facilitated by the integration of security features into the 5G network design stage (e.g., use of EAP-AKA' protocol for user identity authentication and 256-bit encryption for data transmission).
3. AI-Enabled Communication Security: Enhancing the Intelligence of "Threat Detection and Response"
Conventionally, communication security depends on the "manual rules" which are challenging when dealing with newly arisen or unknown threats. By integrating AI, "intelligent protection" will be possible. Some of the movements are:
AI-Driven Threat Detection: AI algorithms (e.g., deep learning and anomaly detection) are employed to analyze communication traffic and behavioral data to find out "new phishing emails", "unknown DDoS attacks", and "malware behaviors" that traditional rule-based methods hardly ever discover.
AI Automated Response: Upon identifying security threats, an AI system automatically initiates the protective actions (e.g., blocking malicious IPs, isolating infected terminals, and updating firewall rules) that drastically shorten the time interval for response from "minutes" to "milliseconds".
AI Security Risk Prevention and Control: At the same time, it tries to avert "security risks of AI itself" (e.g., AI model tampering and training data contamination) so as to maintain the security and reliability of AI-driven protection systems.
Communication security is the "cornerstone" of the digital era. The main thing is to provide the "confidentiality, integrity, availability, authenticity, and non-repudiation" of data along the entire "sending-transmission-receiving-storage" chain, which is achieved by the joint effort of "technology, management, and institutions". From security in a personal mobile call and payment, to secure transmission of enterprise core data and stable business communication, and even to security in command transmission for national critical infrastructure, communication security runs through all scenarios. The threats to communication security have been made more intricate with the progression of new technologies, but the protection technologies have also been constantly upgrading. In the coming years, communication security will go towards the "more intelligent, more proactive, and more adaptable to new scenarios" direction, thus, becoming a core support for the proper functioning of the digital economy.
