1. A communications device, comprising:

  • one or more non-volatile memories capable of being partitioned into at least a first partition and a second partition, the first partition for storing at least a portion of device system software, the at least a portion of device system software being associated with a first security element, the second partition for storing at least a portion of a service processor, the at least a portion of the service processor having one or more system execution properties enabling the at least a portion of the service processor to enhance or augment the device system software, the at least a portion of the service processor being associated with a second security element; and

    one or more processors configured to execute one or more instructions that, when executed by the one or more processors, cause the one or more processors to;

    verify an integrity of the at least a portion of device system software using the first security element,verify an integrity of the at least a portion of the service processor using the second security element,obtain the at least a portion of the service processor from the one or more non-volatile memories,execute the obtained at least a portion of the service processor, thereby enhancing or augmenting the device system software, andupdate, install, remove, or modify the at least a portion of the service processor in the second partition of the one or more non-volatile memories without affecting the at least a portion of the device system software in the first partition.
