Key Management Centre

Industry leading risk management and control

The best of both worlds in revenue protection and smart management of resources.

As a supply authority, the best tools are essential to managing your Supply Group Codes (SGC), approved Meter Manufacturers and Vending System Operators. The STS Key Management System (KMS) gives your service the edge. The KMS supports STS standard 600-4-2 for key management using internationally accepted algorithms such as AES and Elliptic Curve.


Vending Authorisation

The load Authorisation feature now allows SGC owners to allocate SGC vending access to authorised Vending Systems.

Vending Key Expiry

SGC owners can enable Vending Key Expiry, which ensures that each Vending Key has a limited life in case of Vending System Operator change.

Usage Limits

Vending Key Usage Limits can also be set by SGC owners, allowing full usage control of their Vending Keys.


The STS Association

The STS Association was responsible for the original Key Management System which manages all international SGCs today.


Eskom was the first Supply Authority world-wide to implement the Key Management System. Eskom manages all of their SGCs issued in South Africa using the KMS.
