摘要： A method of improving the operation of a processor executing a cryptographic process, by automatically detecting faults during both encryption and decryption operations by the cryptographic process, comprises segmenting the data to be encrypted and encrypting the data segments using a complex non-linear algorithm that can lead to faults; computing an output parity bit from a selected step of the algorithm for a selected data segment, based on the input value of that segment; comparing the actual output parity bit of the selected segment with the computed output parity bit for that segment; and determining whether a fault exists, based on whether the actual output parity bit matches the computed output parity bit for the selected segment.

摘要： Embodiments relate to a concept for observing a ring (100; 200) of interconnected inverting circuit elements (110; 210). In the ring, an output of a first inverting circuit element is coupled to an input of a second inverting circuit element. Respective present output signals of the inverting circuit elements are indicative of the ring's present state. The concept includes monitoring (310; 410), in response to an initial unstable state of the ring, an output of at least one of the inverting circuit elements (110; 210) in at least two observation time instants or at least two outputs in at least one observation time instants to obtain at least two observations of the at least one output; and combining (320; 420) the at least two observations to obtain a response quantity in response to the ring's initial unstable state.

摘要： A method of determining whether a mass serialization engine is cryptographically secure is provided herein. The method includes performing (202) a specified number of mass serializations to generate a corresponding number of mass serialization sets. A size of the mass serialization sets is increased from a first portion size to a second portion size by the mass serialized engine. The method further includes determining (204) a corresponding number of collisions for each of the specified number of mass serializations. Additionally, the method includes comparing (206) the number of collisions to an expected number of collisions. Further, the method includes determining (208) whether the mass serialization engine is cryptographically secure based on the comparison.
