A Hardware Architecture of NIST Lightweight Cryptography applied in IPSec to Secure High-throughput Low-latency IoT Networks

The Internet-of-things (IoT) has rapidly grown in recent years, making it an integral part of many areas our lives. Many IoT networks require high data throughput and low latency, allowing for real-time communication transmission, enabling improved efficiency, cost savings, enhanced decision-making capabilities various industries such as manufacturing, healthcare, transportation, smart cities. However, with the increasing amount being transmitted, security high-speed becomes a critical concern. In this paper, we proposed hardware architecture Ascon, NIST Lightweight cryptography standard to enable high-throughput, low-latency services IPSec protocols. Results show that ESP protocol can achieve maximum 8.806 Gbps minimum latency 427ns only 2812 Slice. This core together Ascon implementation be used gateways provide high-speed, networks.
