Recently, several hardware implementations for elliptic curve cryptography have been proposed but few of them considered the dual-field functions, real-time requirement, hardware efficiency, and power analysis resistance as a whole. In this paper, a new unified division algorithm and a free pre-computation scheme are introduced to accelerate the GF(p)/GF(2)(More)
A multi-functional cardiac signal processor (CSP) with integrated sensor interfaces is designed for mobile healthcare applications, especially for heart activity diagnosis in different phases. Applying dedicated processing engines, the CSP extracts critical cardiac signal features based on compressed data with 90% storage reduction, while keeping the data(More)
Nowadays, differential power-analysis (DPA) attacks are a serious threat for cryptographic systems due to the inherent existence of data-dependent power consumption. Hiding power consumption of encryption circuit or applying key-blinded techniques can increase the security against DPA attacks, but they result in a large overhead for hardware cost, execution(More)
To enhance the data security in network communications, this paper presents a dual-field elliptic curve cryptographic processor (DECP) supporting all finite field operations and elliptic curve (EC) functions. Based on the fast radix-4 unified division algorithm, the execution time can be significantly reduced by a factor of three. By exploiting the hardware(More)
Correlation power-analysis (CPA) attacks are a serious threat for cryptographic device because the key can be disclosed from data-dependent power consumption. Hiding power consumption of encryption circuit can increase the security against CPA attacks, but it results in a large overhead for cost, speed, and energy dissipation. Masking processed data such as(More)
