Abstract: A method of data transfer in an electronic device including a secure module, which includes a processor and a secure element, an application processor, and a sensor, may include: switching an operation mode of the processor to a bypass mode; performing a cross-authentication, by the application processor and the secure element; generating a session key, by the application processor and the secure element, when the cross-authentication is succeeded; switching the operation mode of the processor to a normal mode; encrypting, by the secure module, sensing data provided by the sensor using the session key; transferring the encrypted sensing data from the processor to the application processor; and/or acquiring, by the application processor, the sensing data by decrypting the encrypted sensing data using the session key.
