Abstract: Various embodiments relate to a method for storing and reading data from a memory. Data words stored in the memory may be grouped, and word specific parity information and shared parity information is generated, and the shared parity information is distributed among the group of words. During reading of a word, if more errors are detected than can be corrected with word parity data, the shared parity data is retrieved and used to make the error corrections.

Abstract: A device, including: an unsecure non-volatile memory; a secure device including: a processor; and a secure non-volatile memory; wherein the secure device is configured to: calculate a TMC value from an offset and a base value; store a TMC version value in the secure non-volatile memory and the insecure non-volatile memory, wherein the TMC version value is updated when TMC value is incremented the first time after the secure device is powered up; store the base value in the unsecure non-volatile memory; store the offset value in the unsecure non-volatile memory when the secure device is in a system power down state; store the offset value in the secure non-volatile memory when the secure device is in a rescue state; and store a TMC link value in the unsecure memory, wherein the TMC link value is based upon the base value and TMC version value stored in the unsecure memory.

Abstract: Various embodiments relate to a circuit system, including: an original circuit; a dual circuit, wherein the dual circuit is a dual of the original circuit; an input inverter connected the dual circuit, wherein the input inverter inverts system inputs; an output inverter connected to one of the original circuit and the dual circuit, wherein the output inverter inverts the output of the connected original circuit or dual circuit; and a comparator receiving and comparing the output of the invertor and the output of one of the original circuit and the dual circuit not connected to the inverter, wherein the comparator indicates an error when the received outputs are not identical and indicating no error when the received outputs are identical.

Abstract: A method for protecting data includes encrypting information to generate a first tweak, combining a data block with the first tweak, encrypting the tweaked data block to form encrypted data, combining the encrypted data with the first tweak, and providing the combined encrypted data for storage in a memory address. Storing the combined encrypted data at the memory address generates a first stimulus different from a second stimulus generated by storing same encrypted data combined with a second tweak at the memory address. The first stimulus is generated based on the first tweak and the second stimulus is generated based on the second tweak.
