    摘要： A program execution device capable of protecting a program against unauthorized analysis and alteration is provided. The program execution device includes an execution unit, a first protection unit, and a second protection unit. The execution unit executes a first program and a second program, and is connected with an external device that is capable of controlling the execution. The first protection unit disconnects the execution unit from the external device while the execution unit is executing the first program. The second protection unit protects the first program while the execution unit is executing the second program.

    摘要： A semiconductor memory card comprising a control IC 302, a flash memory 303, and a ROM 304. The ROM 304 holds information such as a medium ID 341 unique to the semiconductor memory card. The flash memory 303 includes an authentication memory 332 and a non-authentication memory 331. The authentication memory 332 can be accessed only by external devices which have been affirmatively authenticated. The non-authentication memory 331 can be accessed by external devices whether the external devices have been affirmatively authenticated or not. The control IC 302 includes control units 325 and 326, an authentication unit 321 and the like. The control units 325 and 326 control accesses to the authentication memory 332 and the non-authentication memory 331, respectively. The authentication unit 321 executes a mutual authentication with an external device.

    摘要： In a data processing apparatus that switches between a secure mode and a normal mode during execution, the secure mode allowing access to secure resources to be protected, the normal mode not allowing access to the secure resources, when the secure resources increase in the secure mode, the load on a protection mechanism for protecting the resources becomes large. Thus, there is a demand for data processing apparatuses that are able to reduce secure resources.The present invention relates to a data processing apparatus that stores therein a secure program including one or more processing procedures which use secure resources and a call instruction for calling a normal program to be executed in a normal mode. While executing the secure program, the data processing apparatus calls the normal program with the call instruction and operates according to the called normal program.

    摘要： An authentication communication system includes an storage medium having an area for storing digital information and an access device for reading/writing digital information from/into the area. The access device authenticates whether the storage medium is authorized according to a challenge-response authentication protocol in which scrambled access information generated by scrambling the access information which shows the area is used. The storage medium authenticates whether the access device is authorized. When the access device and the storage medium have authenticated each other as authorized devices, the access device reads/writes digital information from/into the area in the storage medium according to the access information separated from the scrambled access information by the access device.

    摘要： An information processing apparatus switches between an Operating System 1 and an Operating System 2 during operation and comprises: a storing unit including a first area storing data managed by OS1, a second area storing a reset handler containing instructions for returning to OS2 and for branching to OS2, and a switching unit that switches connection/disconnection of the first area with outside; a table storing unit storing information showing the reset handler's position; a CPU having a program counter and executing an instruction at a position indicated by positional information in the program counter; and a management unit that, when instructed to switch from OS1 to OS2 while the apparatus is operating with OS1, instructs the switching unit to disconnect the first area and the CPU to reset. When instructed to reset itself, the CPU initializes its state and sets the reset handler positional information into the program counter.
