漏洞信息
The NIST SP 800-90A default statement of the Dual Elliptic Curve Deterministic Random Bit Generation (Dual_EC_DRBG) algorithm contains point Q constants with a possible relationship to certain "skeleton key" values, which might allow context-dependent attackers to defeat cryptographic protection mechanisms by leveraging knowledge of those values. NOTE: this is a preliminary CVE for Dual_EC_DRBG; future research may provide additional details about point Q and associated attacks, and could potentially lead to a RECAST or REJECT of this CVE.

Dual Elliptic Curve Deterministic Random Bit Generation 安全漏洞
漏洞信息
Dual Elliptic Curve Deterministic Random Bit Generation(Dual_EC_DRBG)是美国国家标准技术研究院(NIST)所研发的一套随机数生成技术标准。该标准主要用在加密工具中,在加密数据时生成随机数。 Dual_EC_DRBG中的NIST SP 800-90A默认配置中存在安全漏洞,该漏洞源于算法中包含的‘point Q’常量可以确定‘万能密钥’值。上下文相关的攻击者可通过已知的值利用该漏洞破坏加密保护机制。
