Class topic

Post 1. 【Introduction to 5G】5G security protection

Air interface encryption uses parameters that change regularly to convert sent data. When receiving data, the same parameters are used for inverse conversion to restore the data. In this way, the ciphertext is used for transmission over the radio interface to enhance data transmission security.. .…(more)

Post 2. [Introduction to 5G] 5G air interface main security threats and response

In a 5G network, the Uu port between the UE and gNodeB is a public open interface that can be used by attackers to attack the 5G network. what are the main 5G airdrop security threats? How to defend against the security threat of data eavesdropping and tampering?..…(more)

Post 3. 【Introduction to 5G】Introduction to EN-DC protocol architecture

Due to the early freeze of the EN-DC protocol, Option4 series and Option7 series was postponed to March 19.. .(more)
