nist p-256椭圆曲线算法 NIST P-256是一种基于椭圆曲线算法的公钥加密算法。它被广泛用于各种应用,包括数字签名、密钥交换和加密算法。 椭圆曲线密码学是一种现代的公钥密码学方法,与传统的RSA算法相比,具有更高的效率和更短的密钥长度。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...
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...

在P-256中,使用的是一条特定的椭圆曲线,其定义方程为y^2 = x^3 - 3x + b mod p,其中p是一个大素数,通常为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对数问题的困难性。在P-256中,曲线上的点对应于公钥,而曲线的基点和系数...
