Abstract
A data processing system includes a module for generating and distributing random masks to a number of cryptographic accelerators while providing for fewer total interconnects among the components generating the random masks. The module segments the tasks associated with generating random masks across a number of modules and blocks such that routing and timing problems can be minimized and layout can be optimized. A method for generating and distributing random masks to a number of cryptographic accelerators is also provided. The random masks are utilized by cryptographic accelerators to protect secret keys, and data associated with those keys, from discovery by unauthorized users.
