Electromagnetic radiation and information security protection technology
Lightning electromagnetic pulse protection:
The technology of lightning electromagnetic pulse protection has matured. In China, major lightning protection enterprises and departments can design and implement a complete integrated solution for lightning electromagnetic pulse protection based on different protection objects - lightning protection system. The complete lightning protection system includes five major parts: direct lightning protection, grounding protection, equipotential connection, electromagnetic shielding, and overvoltage protection.
Electromagnetic pulse attack protection:
The main idea of high-energy electromagnetic pulse weapon protection and lightning electromagnetic pulse protection technology is actually exactly the same, both are processes of suppression, diversion, and discharge into the ground. However, due to the fast release speed and large spectrum span of high-energy electromagnetic pulses, especially nuclear high-energy electromagnetic pulses, it is necessary to quickly reflect the medium (nanosecond level), cooperate with the shielding body to quickly clamp and reduce the electromagnetic energy level, and then discharge into the ground through the grounding system.
At present, the most commonly used high-energy electromagnetic pulse weapon protection technologies are interface window technology, shielding equipment, etc.
Electromagnetic radiation protection technology:
There are various types of electromagnetic radiation, but their main technologies are generally the same, all of which use high conductivity materials to build shielding layers to separate or reduce the intensity of electromagnetic radiation. At present, the main electromagnetic shielding layers are metal shielding layer and multi ion shielding layer.
At present, the electromagnetic radiation protection products appearing in the market mainly include small shielding films, shielding clothing, and shielding coatings.
Electromagnetic information security protection technology:
Electromagnetic information security protection technology mainly refers to electromagnetic energy shielding technology, which uses highly composite shielding materials or substances to completely isolate the electromagnetic information leakage generated by the operation of electronic devices inside the shielding body through seamless connection technology.
The main protection technologies for electromagnetic information security are the protection part of TEMPEST technology, which mainly includes radio frequency electromagnetic shielding technology, signal entry protection, new shell covering material technology, integrated equipotential connection technology, etc.
