Analysis of security threats and protocols for LTE networks

Security is an important issue in information and communication fields as it protects information and data from unauthorized access. In order to provide perfect security, the user and the device connected to data and communication network must be authenticated. The perfect security can be achieved by providing the protection to a system to attain the applicable objectives of preserving the integrity, availability, and confidentiality of the information system resources. In data and communication networks one can communicate with each other by different means, such as wired, wireless, or combination of both. In this paper, various security aspects for Long Term Evolution (LTE) networks have been reviewed in terms of authentication techniques, key management system, effects of attacks, etc.
