Abstract
Techniques for preventing tampering with programmable read-only memory of an integrated circuit are provided. A method according to these techniques includes performing a randomized read of data stored in the programmable read-only memory based on an input from an entropy source, writing the data to one or more registers of the integrated circuit, and initializing one or more components of the integrated circuit using the data stored in the one or more registers.
