DATA TRANSMISSION APPARATUS CAPABLE OF SECRET KEY ENCRYPTION BASED ON INVOLUTORY MATRIX AND OPERATING METHOD THEREOF

摘要

A data transmission apparatus capable of matrix-based secret key encryption and a method of operating the same are disclosed. According to the present invention, a data transmission device capable of encrypting a secret key based on an involutory matrix and a method of operating the same are encrypted by transmitting a message to a data receiving device based on a secret key designed based on the characteristics of the matrix. Since the data receiving apparatus can support the restoration of the original data by performing a simple decryption operation based on the secret key, it is possible to provide high security even when transmitting and receiving data between devices having relatively low computational performance. .
