The next generation passive optical network is the major technique choice of broadband access and the FTTx network. This paper describes threat models in the optical access network, focuses on the security issues and needs which the next generation PON system faces, and proposes one kind of high speed encryption algorithm-multi-byte churning algorithm for the future PON. The simulation result shows that this algorithm supports a higher speed and the security has been enhanced obviously. FPGA implementation shows that the algorithm can achieve 10.9 Gbps and well support the security requirements in next-generation PON standard. Finally, this paper analysis its features from key space, time domain correlation and resource availability.
