Microsoft Kernel Mode Security Support Provider Interface (ksecdd.sys)

Microsoft Corporation - FIPS 140 #891

historicalLevel 1

KSECDD.SYS runs as a kernel mode export driver, and provides cryptographic services, through their documented interfaces, to Windows Vista kernel components. It supports several cryptographic algorithms accessible via a FIPS function table request irp (I/O request packet).

Algorithm families of the CAVP certificates listed for this module, plus post-quantum algorithms named in its documents.

CAVP algorithm certificates (8)

Each approved algorithm in a FIPS 140-3 module needs its own NIST CAVP certificate. Older numeric certificates link to their NIST page; ACVP certificates (A1234) can be looked up in the CAVP validation search.

Tested environments

  • Microsoft Windows Vista Ultimate Edition (x64 version) (single-user mode)
  • Microsoft Windows Vista Ultimate Edition (x86 Version)

Operational environments the module was tested on, as listed by NIST CMVP.
