key management system


As a supply authority you need the best tools to manage your Supply Group Codes (SGC), approved Meter Manufacturers and Vending System Operators. The STS Key Management System (KMS) gives you the edge.

The KMS supports STS standard 600-4-2 for key management using internationally accepted algorithms such as AES and Elliptic curve.

key features


Vending Authorisation

The load Authorisation feature now allows SGC owners to authorise which Vending Systems have access to vend to their SGCs.


Vending Key Expiry

SGC owners can enable Vending Key Expiry, ensuring that each Vending Key has a limited life should they wish to change Vending System Operators.


Usage Limits

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