    Abstract: According to various embodiments, an electronic device may include: a housing, a flexible display configured to change in a form in response to a movement of the housing, a communication circuit configured to perform communication through a plurality of communication schemes, and a processor operatively connected to the communication circuit. The processor may be configured to: based on identifying that the form of the display is changed from a second form to a first form, control the communication circuit to perform a communication connection in a first communication connection scheme different from a second communication connection scheme designated for the second form among the plurality of communication schemes and perform communication through the first communication connection scheme in the first form.

    Abstract: An integrated circuit includes a system memory, a security processor and a non-security processor. An attack against the integrated circuit is made more difficult based on using a key generated by the security processor. The security processor, as an example, reads a program image from the system memory and generates the key based on the program image. In some instances, a dedicated communication channel is provided for communication between the non-security processor and the security processor. The dedicated channel may be used to provide the key to the non-security processor for performance of a security operation.
