Abstract
An exemplary security key bootstrapping system determines an application layer session security keyset uniquely associated with a client device and based on a subscriber identity master security credential. The subscriber identity master security credential is permanently stored within a component of the client device and is also stored on a subscriber identity management server associated with a provider network by which the client device is communicatively coupled with an application server system. The security key bootstrapping system uses the application layer session security keyset as a credential to provide end-to-end security for an application layer session between the client device and the application server system over the provider network. Neither the component of the client device nor the subscriber identity management server obtains the subscriber identity master security credential from an exchange of the subscriber identity master security credential over the provider network.
