Perfect classified channel (PCC) was proposed as a hardware-based Layer-1 encryption system that prevents of leakage of packet information and any indication of the existence of packets. PCC can provide high-throughput communication, which is encrypted using AES encryption hardware, while maintaining DC balancing, which is generally managed using the 8B/10B or 64B/66B coding algorithms. In this paper, we propose two methods to classify a framing signal that indicates a boundary between packets, for PCC. These methods facilitate an improved level of security compared with existing communication channels and make PCC more secure. This paper describes the details of the PCC architecture including the hardware costs while also verifying the DC-balance performance of PCC and the confidentiality of framing signals.
