Study Notes

COMSEC Overview

  • Poor COMSEC practices do not reduce adversarial leverage or INTEL risk concerning U.S. objectives.
  • COMSEC aims to deny unauthorized access to government telecommunications related to national security while ensuring authenticity.

Key Terminology

  • A tier 3 account is termed a Local Element.
  • Traffic security is not part of COMSEC.
  • The two primary types of encryption are asymmetric and symmetric.
  • Key Encryption Key (KEK) safeguards Traffic Encryption Key (TEK) during transmission and storage.

SKL Functionality

  • The SKL (Simple Key Loader) manages both traditional and modern electronic keys for ECM devices.
  • SKL can utilize multiple CIKs for secure communications.
  • The SKL UAS (User Application Software) facilitates key management and loading into ECUs.
  • DS-101 protocol enables KEYMAT transfer with key tag information.

Equipment and Data

  • Modern equipment is typically software-based.
  • A unique Equipment Profile is generated for each ECU, enhancing user prompts during data downloads.
  • Black Data refers to keys with additional payload data, while RED keys are unencrypted.

Encryption Details

  • Traditional (symmetric) key refers to encryption where the same key is used for both encryption and decryption.
  • TrKEK encrypts and decrypts other keys for secure operations.
  • An Equipment Record requires selecting an Equipment type after naming.

User Operations

  • Key loading procedures differ per ECU, and user manuals should be consulted for specific instructions.
  • Filling devices, such as the SKL, are used to load COMSEC equipment.
  • The SKL UAS provides a menu bar with icons RECV & LOAD for simplified navigation.
  • Tab recognition for active involvement in SKL UAS is indicated when it displays on top of other tabs.

Loading Procedures

  • To load assigned key into an ECU, necessary tabs must be activated and the Load ECU Wizard followed.
  • Unassigned key loading involves selecting the appropriate key tab and relevant segments without wizard assistance.

Troubleshooting and User Assistance

  • If the SKL UAS doesn't launch after login, manually initiate it via the CoreLib screen.
  • Equipment Profiles assist in providing step-by-step help during ECU loading operations.

Control Functions

  • The GP4 button enables or disables navigation functions on the SKL interface.
  • KOV-21 functions are provided by the CoreLib for managing secure access in SSO or User accounts.

Hardware Connections

  • A Fill Cable is essential for connecting SKL to an ECU during key loading processes.
