Abstract: An electronic device according to an embodiment includes a first random number generator module, a second random number generator module, a buffer memory configured to store random number data, and a processor configured to be operatively connected to the first random number generator module, the second random number generator module, and the buffer memory, wherein the processor is configured to acquire a first random number sequence from the first random number generator module to store the acquired first random number sequence in the buffer memory, generate a third random number sequence obtained by changing the first random number sequence based on a second random number sequence acquired from the second random number generator module, and generate an encryption key based on the third random number sequence. In addition, various other embodiments are possible.
