Descriptions

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.

El procedimiento por defecto del NIST SP 800-90A del algoritmo Dual Elliptic Curve Deterministic Random Bit Generation (Dual_EC_DRBG) contiene puntos constantes Q con una posible relación con ciertos valores "skeleton key", lo que podría permitir a atacantes dependientes del contexto romper mecanismos criptográficos de protección mediante el aprovechando del conocimiento de esos valores. NOTA: este es un CVE preliminar para Dual_EC_DRBG, la investigación futura puede brindar detalles adicionales sobre el punto Q y los ataques asociados, y podría potencialmente dar lugar a un RECAST o REJECT de esta CVE.
