A special version of a proxy is the secure proxy that provides secured access to RA queues for communication to the security master of the system. The secure proxy provides basically the same function as a normal proxy. The data burst size is fixed for message sizes to the security master, so there is no support for all the element sizes of the RA. The security master locks down the RA queue to access and direction for each proxy thread so that the software cannot access anything they shouldn’t, so the software only sees a single queue (unlike the normal proxy), and any attempts to access another queue or access it in violation of how the security master defined and an error will be flagged. This allows for a much more controlled setup for passing messages to the security master.
