In 5G, integrity protection of the user plane (UP) between the device and the gNB , was introduced as a new feature. Like the encryption feature, the support of the integrity protection feature is mandatory on both the devices and the gNB while the use is optional and under the control of the operator.

Ciphering is needed when you want that only authorized people can ACCESS TO SEE the data. Integrity is when authorized people can ACCESS TO MODIFY the data . As you can see, both ciphering and integrity need an authentication and authorization phase before.
Read moreHow is user identity protected 5G?
In 5G, a subscriber long-term identity is always transmitted over the radio interfaces in an encrypted form. More specifically, a public key-based encryption is used to protect the SUPI . Therefore, only the SIDF has access to the private key associated with a public key distributed to UEs for encrypting their SUPIs.
Read moreWhich protocol provides integrity and ciphering protection?
In a network security protocol such as IPsec, a MAC may be used to provide integrity protection and origin authentication of messages sent between two peers that have previously established a shared private key.
