摘要： It is possible to achieve the protection of software with reduced overhead. For example, a memory for storing an encrypted code prepared in advance and a decryptor module for decrypting the code are provided. The decryptor module includes, for example, a three-stage pipeline and a selector for selecting one output from the outputs of each stage of the pipeline. When a branch instruction is issued and subsequent inputs of the pipeline are in the order of CD′1, CD′2, . . . , the decryptor module outputs a first decrypted code by performing a one-stage pipeline process to CD′1. Next, the decryptor module outputs a second decrypted code by performing a two-stage pipeline process to CD′2, and the decryptor module outputs a third decrypted code by performing a three-stage pipeline process to CD′3 (and subsequent codes). Therefore, in particular, the overhead to CD′1 can be reduced.

摘要： A front-end processing unit provided in a document processing system receives a request in relation to document processing from an image forming apparatus, and produces a divided job by dividing the document processing job into a unit capable of parallel processing in response to the received request details. The front-end processing unit determines an execution order for each of the divided jobs, and then stores the divided jobs in a plurality of queues. The back-end processing unit obtains a divided job from the queue according to the determined execution order of divided jobs, and executes document processing by executing the obtained divided job, and then returns the document processing result to the image forming apparatus.

摘要： An increase in safety from attacks by use of hardware-like methods by small-sized hardware is achieved. An encryption processing device includes a logical circuit capable of programmably setting logics for executing cipher processing, a memory that stores plural pieces of logical configuration information corresponding to an identical cipher processing algorithm, and a CPU that selectively sets plural logics corresponding to an identical cipher processing algorithm in the logical circuit. Even in processing using an identical cipher key, by changing the logic of the logical circuit for each processing, power consumption in cipher processing can be varied, and places a timing in which malfunctions occur can be varied. Moreover, an increase in the scale of hardware for realizing plural logics can be curbed.

摘要： The data processor includes: a memory device for storing a program compiled by a compiler; and CPU operable to fetch an instruction code included by a program stored in the memory device. Further, the data processor has a filter for judging an instruction code which the compiler never outputs to limit, in action, CPU in case that CPU fetches the instruction code, which limits, in action, CPU in the case where the program is rewritten by not only an undefined instruction, but also an instruction other than an undefined instruction. The level of security is increased by limiting, in action, CPU.

摘要： A program to be executed by a computer is divided into a plurality of code blocks, and, a unique code block ID is allotted to each code block. At the moment when the execution of the program is started, the code block ID corresponding to the execution start address is written in a memory, and in the case when the control transits from the code block to other code block, by use of code block operation values obtained beforehand from these two code block IDs thereof, the code block ID in the memory is updated, and it is judged whether the updated code block ID in the memory and the code block ID allotted to the code block as the execution objective are identical or not so that a control flow error is detected.

摘要翻译： 要由计算机执行的程序被分成多个代码块，并且将唯一的代码块ID分配给每个代码块。 在开始执行程序的时刻，与执行开始地址相对应的代码块ID被写入存储器中，并且在控制从代码块转移到其他代码块的情况下，通过使用代码块 从这两个代码块ID预先获得的操作值，存储器中的代码块ID被更新，并且判断存储器中更新的代码块ID和作为执行目标分配给代码块的代码块ID是否是 相同或不相同，从而检测到控制流量错误。
