LTE Security

Secure links between nodes in LTE network

This course is designed to help participants understand the various security issues surrounding LTE networks. Encryption algorithms used in LTE networks will be discussed in-depth to enhance participants’ understanding of encryption algorithms. Participants will also learn how to manage the security keys involved in LTE networks, the functions of the PKI architecture components, IPsec over Public Internet and Private Backhaul networks.

This course is designed for engineers, managers and other personnel who have a need to acquire a technical overview of the security environment employed within GSM/WCDMA/LTE networks.

It will also be of benefit to those in the wider technical community who have a need to understand the security protocols employed by cellular networks.

At the end of this course, participants will be able to:

  • Explain the security bases for LTE networks
  • List the encryption algorithms
  • Understand how the LTE security feature groups meet certain threats and accomplish certain security objectives: Network access security, LTE Security Encryption etc.
  • Understand Security Keys Management: The differences between the private and public keys, how to exchange keys with security over the network (using original algorithms such as Deffie-Helmann) and how this drives to certificates and PKI
  • Describe the functions of the PKI architecture components
  • Describe concept for IPsec over public Internet and Private Backhaul
