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： 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： 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.
