What are possible security and privacy challenges in 6G?

However, it is estimated that the terahertz in 6G era will have the same problems as the millimeter wave today: weak capability of covering , high cost of deploying network, the premature ecosystem of terminals and so on, which need to be solved by the whole telecom industry together.

6G (sixth-generation wireless) is the successor to 5G cellular technology. 6G networks will be able to use higher frequencies than 5G networks and provide substantially higher capacity and much lower latency .

Malicious behavior and encryption are the main weaknesses. As the last applications of the 6G network, the blockchain and distributed ledger technologies (mainly based on blockchain) are relatively safe, but they may still be the target of malicious behaviors.

6G will be 50 times faster than 5G, 100 times more reliable, offer wider coverage and support ten times more devices per square kilometer . With that kind of speed and power, it’s hard to say exactly what the 6G architecture will look like.
