Course 275: Simple Key Loader (SKL)


The SKL, AN/PYQ-10(C), is the next generation of the currently fielded AN/CYZ-10 Data Transfer Device (DTD). The AN/PYQ-10(C) provides automated, secure and user-friendly methods for managing and distributing cryptographic key material, Signal Operating Instructions (SOI), and Electronic Protection data. This course introduces some of the basic components and activities associated with the AN/PYQ-10(C) in addition to hands-on training. Learners will become familiar with the security features of the SKL, practice the initial setup of the SKL, and will receive and distribute electronic keys using the SKL.


  • Setup and use of the SKL
  • Identify its purpose, capabilities and security features
  • Receive and distribute associated keys

Target audience

All Government of Canada (GC) departments and their contractors, who handle, distribute, account for, store or use the SKL to store electronic keys.
