NIST P-256就是其中一种应用广泛的椭圆曲线算法。 P-256使用的是一条特定的椭圆曲线,即NIST定义的曲线。其数学方程为: y^2 = x^3 - 3x + b mod p 其中,p是一个大的素数,通常是2^256-2^224+2^192+2^96-1;b是一个常数,具体的值通过NIST标准规定。 椭圆曲线密码学的安全性基于解决椭圆曲线离散...
The NIST P-256/P-384 ECDH+ECDSA can be used for elliptic curve key generation, computation of Diffie-Hellman shared secrets as well as for ECDSA signature generation and verification. The NIST P-256/P-384 ECDH+ECDSA family currently includes two IP cores: • XIP4123C for ECDH and ...

In this paper, we present a highly optimized implementation of elliptic curve cryptography (ECC) over NIST P-256 curve for an 8-bit AVR microcontroller. For improving the performance of ECC implementation, we focus on optimizing field arithmetics. In particular, we optimize the modular multiplicati...

This document states that the default curve for the ecdhCurve parameter is prime256v1. https://iojs.org/api/tls.html#tls_tls_createserver_options_secureconnectionlistener Appendix A of this document indicates that prime256v1 is also known as NIST P-256. ...
同时也被设计用于其他微型技术，如植入式医疗设备、道路和桥梁内的压力检测器以及车辆的无钥匙进入。 换句话说，这个算法是对在拥有 "有限的电子资源 "的设备中通过轻量级密码学进行安全保护。也就是说，NIST仍然推荐高级加密标准（AES）和SHA-256用于一般用途。 在此之前NIST 收到了 57 个提案，经过了 ...
