First Claim
Patent Images
1. A system comprising:
- a key repository for storing a key;
a key manager coupled to the key repository including a key generator for creating an authorization token using the key from the key repository; and
an operation provider in communication with the key manager which requests the authorization token from the key manager to provide security for an operation.

Abstract
An authorization token may provide security for operations. The authorization token may be encrypted by a key manager of a head end system so that only a target device may decrypt the authorization token and perform an operation.
