Audit of the Rust p256 Crate https://reports.zksecurity.xyz/reports/near-p256/
@zksecurityXYZ conducted a security assessment of the Rust p256 crate, finding no major issues, with the codebase being well-tested and architecturally sound. The assessment covered elliptic curve operations, ECDSA signature verification, and field arithmetic. This audit report can serve as a learning reference for p256 curves. @zksecurityXYZ 对Rust p256 crate进行了安全评估，未发现重大问题，代码库经过充分测试且架构良好。评估范围包括椭圆曲线操作、ECDSA签名验证和字段算术。本审计报告可以作为p256曲线的学习参考资料。
Notes
- P-256 optimization: Utilize the a=-3 property to accelerate calculations
- ECDSA security: Must use a deterministic nonce (RFC6979)
- Performance key: Precomputing 16 points improves signature speed
- Important vulnerability: Random number generation may produce invalid values
- Optimization tip: Removing redundant operations can speed up by 16%
