ERROR DETECTION FOR ENCRYPTION OR DECRYPTION KEYS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18612406 titled 'ERROR DETECTION FOR ENCRYPTION OR DECRYPTION KEYS

The present description discusses a method for checking a first data element using an electronic device with a processor and memory. The first data element is divided into N second data elements stored in memory, with the first data element being the sum, modulo the dimension of a space containing it, of the N second data elements. An image of the first data element by a LCG function is stored in memory, and the method involves checking if the image of the first data element by the LCG function is equal to the sum, modulo the module of the LCG function, of a product of an integer from 0 to N-1 and an image of the dimension by the LCG function, and of the images of the second data elements by the LCG function.

• The method involves dividing a first data element into N second data elements stored in memory.
• An image of the first data element by a LCG function is stored in memory.
• The method checks if the image of the first data element by the LCG function matches a specific calculation involving the second data elements and the dimension.
• This method helps verify the integrity of the first data element using mathematical calculations.
• The use of the LCG function adds a layer of security and validation to the data checking process.

Original Abstract Submitted

The present description concerns a method of checking a first data element, executed by an electronic device comprising a processor and a memory, wherein the first data element is divided in N second data elements being stored in the memory, and first data element being equal to the sum, modulo the dimension of a space comprising the first data element, of the N second data elements, wherein an image of the first data element by a LCG function is stored in the memory, and the method comprising a step of checking if the image of the first data element by the LCG function is equal to the sum, modulo the module of the LCG function, of a product of an integer varying from 0 to N−1 and an image of the dimension by the LCG function, and of the images of the second data elements by the LCG function.
