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.

Abstract: The present disclosure relates to an electronic device, such as a system on chip, that may perform firmware updates based on user consent. The system on chip includes a nonvolatile memory (NVM), a main processor, a security NVM, and a security processor. The nonvolatile memory (NVM) stores first firmware and a user permission indicator. The main processor Loads the first firmware to boot a security processor. The security NVM contains first version information. The security processor compares version information of the first firmware to the first version information based on the user permission indicator and executes the first firmware in response to the matching of the comparison result. In some examples, the security processor is implemented on the same chip as the main processor.

Abstract: According to various embodiments, an electronic device having a housing including three surfaces at least partially surrounding a space between a first and second surface, an opening formed to one portion of a side surface of the housing, and the portion extending to define a hole connected to the opening. The device includes a tray with four side surfaces and having a length capable of being entirely inserted into the hole, and detachable from the hole. The device further including a fixing structure disposed inside the hole in parallel with one side surface of the tray, and at least partially rotatable about an axis in a first direction about the hole. When inserted entirely into the hole, at least one portion of the tray contacts the fixing structure, and if the fixing structure at least partially rotates in the first direction, the tray is released from the hole.
