Abstract:
1. In a computing device, a method of efficiently establishing a secure communication used for receiving information from one or more modules on the computing device by utilizing a secure shared memory in determining a transport address to be used for the secure communication, the method comprising: generating first random data by a listener module, wherein the first random data is used to identify a first transport address of the listener module, and the first transport address is used to verify that a connector module resides on the computing device and to establish communicate between the listener module and the connector module; storing the first random data by the listener module in the secured shared memory, the first random data identifying the first transport address, the secured shared memory being accessible by the listener and the connector modules, but inaccessible to modules outside the computing device; the listener module listening for communication activity at the transport address identified by the random data; the listener module receiving at the first transport address the information from the connector module to establish that the connector module resides on the computing device; generating second random data, by the listen module, the second random data used to further verify that the connector module resides on the computing device; generating third random data by the connector module, the third random data used to verify that the listener module resides on the computing device; sending the third random data to the first transport address by the connector module; storing the third random data in the secure shared memory by the listen module upon receiving the third random data from the connector module; and retrieving information corresponding to the third random data from the shared memory by the connector module for proving that the listener module resides on the computing device.
