摘要： This document discusses, among other things, systems and methods to communicate data over a data bus during a first period of a clock signal with a uniform power distribution, including providing a complimentary bit state of the data during a first portion of the first period of the clock signal and providing an actual bit state of the data during a second portion of the first period of the clock signal. In an example, the first period can include first, second, third, and fourth portions, and the systems and methods can include providing a complimentary bit state of the data during first and fourth portions of the first period of the clock signal and an actual bit state of the data during a second portion of the first period of the clock signal.

摘要： Apparatus and methods are provided for defending an electronic circuit secret algorithm and secret parameter values against a side-attack. In an example, a method can include receiving first one or more parameters for altering a clock signal of the electronic device at a non-volatile memory register, and altering a frequency of the clock signal of the electronic device during execution of an authentication routine according to the first one or more parameters.

摘要： This document discusses, among other things, a method of distributing authentication keys that can prevent certain forms of circuit fabrication piracy. In an example, a method can include selecting a number of authentication keys for generation at a key generation computer, generating a random number using a random number generator of the key generation computer, generating the number of authentication keys using the random number and a key generation algorithm stored in the memory of the key generation computer, scrambling each of the number of authentication keys using a scrambling routine executing on the key generation computer, and distributing the scrambled authentication keys to an authorized manufacturers.
