# Output

## 5G Security Challenges

## Traditional Security

Traditional security architectures focus on **protection of voice and data**:

1. User identity management based on (U)SIM
2. Mutual authentication between networks and users
3. Securing the path between communicating parties hop-by-hop

## 5G Security

### 1. New Business Model

5G is no longer confined to individual customers.

5G will also serve vertical industries, from which a diversity of new services are going to stem.

**mobile Internet of Things (IoT) devices require lightweight security**

**high-speed mobile services demand high efficient mobile security**.

The network based hop-by-hop security approach may not be efficient enough to build differentiated end-to-end (E2E) security for different services.

There is a need of **a more stringent authentication method** to prevent **unauthorized access to IoT
devices**.

### 2. IT-Driven Network Architecture

**New security concerns are emerging** when new IT technologies (virtualization and Software Defined Network (SDN)/Network Functions Virtualization (NFV)) injecting new vigor into their networks.

**Security cannot be built for 5G services unless the network infrastructure is robust.**

5G security design may need to consider **issues of how to isolate, deploy, and manage virtual network slices securely**

### 3. Heterogeneous Access

The **heterogeneous access** might imply that the access network architecture from different networks are different.

### 4. Privacy Protection
As **open network platforms, 5G networks raise serious concerns on privacy leakage**.

**The service type sensing** may involve user privacy.
