Comparison of 5G with LTE
| Feature | LTE | 5G |
|---|---|---|
| Privacy | Provides encryption between eNodeB (LTE base station) and mobile station, on the radio path | Provides all privacy methods of the existing predecessor technologies |
| Provides ciphering of control plane between user equipment and mobility management entity | Prevent unauthorized modification in user data to maintain integrity | |
| Support 128 bit algorithms. | Support 256 bit algorithms | |
| Authentication Key Agreement | The key is shared between authentication server function (AUSF) and universal integrated circuit card (UICC) | In addition to LTE it preserves the confidentiality of the initial NAS (non-access spectrum) message between the network and devices |
| By this, mutual authentication is assured between the network and user equipment (UE) | It provides Access-agnostic authentication which supports both 3GPP and non-3GPP access technologies | |
| Security Anchor Function (SEAF) | Not Applicable | It allows re-authentication of user devices using SEAF when they travel between distinguished access networks or serving the network without performing the full authentication |
| Subscriber Permanent Identifier | Prior to network authentication the identifier is sent in the form of plaintext | Subscription Concealed Identifier (SUCI) is designated to provide the use of home network public key mechanism to encrypt the MSIN part of the subscriber identifier |
| It protect the confidentiality of the initial NAS messages between the UE and the network | ||
| Home Control | Not Applicable | The presence and service request by UE from visited public mobile network (VPMN) is verified by home public mobile network (HPMN), which is useful in roaming and fraud prevention scenarios |
| Network Exposure Function (NEF) | Not Applicable | Allows secure provisioning of information in 3GPP network along with authorized and authenticated network functions |
| Uses certificate based mutual authentication | ||
| Being authenticated, NEF analyses, if the application function is authorized to send the service request to 3GPP networks | ||
| Security Edge Privacy Protection | Not Applicable | Acts as security gateway on interconnections of HPMN and VPMN, and thus, protecting the home network edge |
