Module Name
YubiKey 5 Cryptographic Module
Validation Dates
04/22/2021;08/19/2021
Caveat
When operated in FIPS mode, installed, initialized, and configured as specified in Section 3 of the Security Policy. The module generates cryptographic keys whose strengths are modified by available entropy.
Security Level Exceptions
- Physical Security: Level 3
- EMI/EMC: Level 3
- Design Assurance: Level 3
- Mitigation of Other Attacks: N/A
Description
The YubiKey 5 cryptographic module is a secure element that supports multiple protocols designed to be embedded in USB and/or NFC security tokens. The module can generate, store, and perform cryptographic operations for sensitive data and can be utilized via an external touch-button for Test of User Presence. The module implements several major functions - Yubico One Time Password (OTP), FIDO/FIDO2, FIDO/U2F, PIV-compatible smart card, OpenPGP smart card, and OATH OTP authentication.
