Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover nonce reuse through static analysis, fuzzing, or known-answer tests.

SA-8 Security and Privacy Engineering Principles partial match

Engineering principles include correct use of cryptographic primitives such as unique nonces per key.

SC-13 Cryptographic Protection partial match

Selecting and implementing appropriate cryptographic algorithms and modes reduces nonce-reuse exposure.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly prevent nonce/key reuse errors in cryptographic implementations.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.24 Use of cryptography mostly match
prevents

Mandates proper cryptographic key and nonce management, directly preventing nonce/key-pair reuse.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect nonce reuse, yet the control addresses many other issues beyond this CWE.

A.8.28 Secure coding partial match
prevents

Secure-coding rules can require unique nonces, but the control is broader than this single weakness.
