To Trust or Not to Trust: Data Origin Authentication for Group Communication in 5G Networks

摘要: With the expected massive increase in high-bandwidth applications over 5G cellular networks, efficient use of radio-network and core-network infrastructures becomes essential. Group communication is a method for transmitting data efficiently from one source to many receivers. In this paper we study security provided terms authenticity integrity group networks. We identify that current solutions involve trusting benignity operational network operators as well its users since do not provide origin authentication. Based on insight, present two attack scenarios which an adversary exploits level such arbitrary can be injected maliciously while receivers consider if they were sent by claimed source. evaluate potential approaches authentication show future research required general solution.
