Title:
ELECTRONIC DEVICE FOR IMPROVING RANDOMNESS OF SECURITY MODULE BY USING MULTI-NON-DETERMINISTIC RANDOM NUMBER GENERATOR MODULE
Document Type and Number:
WIPO Patent Application WO/2022/215868
Kind Code:
A1
Abstract:
An electronic device according to various embodiments comprises: a first random number generator module; a second random number generator module; a buffer memory for storing random number data; and a processor that operates by being operatively connected to the first random number generator module, the second random number generator module, and the buffer memory, wherein the processor may obtain a first random number sequence from the first random number generator module and store same in the buffer memory, generate a third random number sequence obtained by changing the first random number sequence on the basis of a second random number sequence obtained from the second random number generator module, and generate an encryption key on the basis of the third random number sequence. Various other embodiments are possible.
