Enhancing 5G/IoT Transport Security Through Content Permutation

Internet of Things (IoT) or massive machine-type communications (mMTCs) is one of the essential aspects addressed by 5G mobile telecommunications. Some 5G core networks will be deployed with software-defined networking (SDN) where security is an important issue. The overhead of offering security in 5G is high, which is typically incurred in encoding and decoding. This paper proposes the enhanced content permutation algorithm (eCPA) that can effectively implement secret permutation in a 5G/IoT transport network with the P4 SDN switches to protect the 5G packets (especially for IoT). The encoding/decoding speed, including packet routing, can be up to 6.4 Tb/s, which is the fastest in the world.
