Abstract: A root silo that authorizes one or more clients to access one or more services at one or more servicing silos receives a request from a client for interaction with a service. The root silo identifies a servicing silo as an available provider of the service for interacting with the client and generates a servicing certificate that contains (i) service entitlement information showing that the client is entitled to interact with the service at the servicing silo, (ii) location information identifying a location of the servicing silo, and (iii) one or more keys for use in secure communication between the client and the servicing silo. Having generated the servicing certificate, the root silo sends the servicing certificate to the client for the client to use when interacting with the service at the servicing silo.

Abstract: A software licensing system includes a license generator located at a licensing clearinghouse and at least one license server and multiple clients located at a company or entity. When a company wants a software license, it sends a purchase request (and appropriate fee) to the licensing clearinghouse. The license generator at the clearinghouse creates a license pack containing a set of one or more individual software licenses. The license generator digitally signs the license pack and encrypts it with the license server's public key. The license server is responsible for distributing the software licenses from the license pack to individual clients. When a client needs a license, the license server determines the client's operating system platform and grants the appropriate license. The license server digitally signs the software license and encrypts it using the client's public key. The license is stored locally at the client.
