Abstract

The practical applications of Wireless Sensor Networks WSNs in vulnerable areas require the communication data possessing confidentiality, integrity and freshness. In this paper, we present the implementation and simulation of a hardware security coprocessor called EasiSec based on system-on-chip SoC technology for WSN. Compared with existing works, our unique features include: 1 A fingerprint-based key management FKM module to extract key elements from program memory and build secret keys for cryptographic coprocessor, which can resist the key compromise impersonation attack; 2 A reusable optimised logic cell ROLC to complete encryption and decryption, and minimise the hardware overhead; 3 An authentication module based on Linear Feedback Shift Register LFSR to provide two-party data with integrity and freshness. The design is mapped on FPGA and ASIC design. Results show the hardware overhead of our design is 16.5% less than common designs and the execution time is shorter than other coprocessors.
