100 Gb/s dynamically programmable SDN-enabled hardware encryptor for optical networks

We have successfully demonstrated an on-demand programmable hardware encryptor for optical networks enabled by the software-defined network (SDN) and tested its application in a quantum key distribution (QKD) use case. believe our proposed is unique way that it combines encryption algorithms with 100G Ethernet interface to provide high-transmission capacity flexible security. formed library consisting of AES-256, AES-192, AES-128, Camellia-256, XOR, no-encryption configurations. Our system has shown throughput 91.3 Gb/s AES variations 90.2 while theoretical throughputs were 160 Gb/s. In addition, goodputs all schemes measured as at least 90.4 For faster reconfiguration field-programmable gate array (FPGA), partial technology been used, times 2.6 s 2 decryption achieved. The FPGA configuration rate was 3.35 MB/s. When design QKD case 256-bit keys, highest achieved consumption 27 keys/s, which corresponded minimum granularity 474 MB per key. Thus, key, up 6912 b/s encryptor’s end-to-end latency using 300k standard Internet Control Message Protocol (ICMP) pings. schemes, 0.093 m mathvariant="normal">s ± 0.028 on average, but encryption/decryption processes did not meaningful impact microsecond precision.
