摘要: Low-cost Systems-on-Chip (SoC) are becoming very useful for building Internet of Things coordinators/gateways because the embedded microprocessors allowing execution complex software collecting and sending information to cloud servers. However, if this has be securely sent through Internet, Transport Layer Security (TLS) handshake is required, thus implying heavy cryptographic operations. In work, design an area-improved Elliptic Curve Cryptography (ECC) co-processor with great performance figures, presented. The developed requires less than 3500 LUTs when implemented in Zynq devices, while performing ECC scalar-point operation around 400us operating at 50MHZ. This accelerator can free main microprocessor from these operations, enabling SoC connected Internet.
