Abstract: PURPOSE: An MPEG music file player having a voice alarming function for a vehicle is provided to monitor an alarming situation of a vehicle in a state of alarm message data of a user being stored in a memory, and to automatically inform the user of an alarming message relating to the alarming situation, so as to reduce another voice alarming system cost. CONSTITUTION: An alarming sensor(10) is mounted on a vehicle. A microphone circuit(20) amplifies a user's alarming message voice signal inputted through a microphone(21) of a user and filters the amplified signal. An MP3 player operator(30) outputs an alarm recording command signal and an MP3 player operation command signal. If an MP3 replay signal is inputted, an MP3 decoder(40) decodes MP3 stored in a memory(41) and encodes inputted alarm message data with an ADPCM(Adaptive Differential Pulse Code Modulation) system to store the alarm message data in the memory(41). If alarm message data of the memory(41) is inputted, the MP3 decoder(40) decodes the alarm message data with the ADPCM system. If the alarm recording command signal is inputted, a micro computer(50) converts an alarm message voice signal into the alarm message data. If the MP3 player operation command signal is inputted, the micro computer(50) outputs an MP3 operation signal and reads the alarm message data of the memory(41), according to an output signal monitoring result. The micro computer(50) applies the read data to the MP3 decoder(40). A D/A(Digital to Analog) converter(70) converts the decoded MP3 and the decoded alarm message data into analog signals, and outputs the analog signals through a speaker(60).

Abstract: PURPOSE: An information processing equipment is provided to reduce the relation between the data process in an IC card chip and its consumption current by processing the data in the IC card chip after it is transformed so it is difficult to presume the data process and the cipher key from the consumption current wave shape. CONSTITUTION: A cipher text is subjected first to initial permutation IP(902). This permutation is performed by using an initial permutation table to exchange 64-bit data of the cipher text on the one-bit unit basis. A series of such operations is repeated sixteen stages to inverse permutation (IP<-1>) 915 of the initial permutation. At each stage, a process called an f function 903 is calculated by inputting data of 32 bits of either the first or second half at the preceding stage and the cipher key, and then an exclusive logical OR operation 909 is performed by using the output of the f function and 32 bits of the remaining half at the preceding stage. Data of the cipher key is also exchanged. Data of the cipher key is first subjected to selectable permutation PC-1(905) by using a table PC-1. Thereafter, data of the cipher key is subjected to selectable permutation PC-2 (908) by using a table PC-2. At the next stage, each set of 28 bits of the cipher key rounded in accordance with an RS table is used. In this embodiment, before the IP process, the transforming process a(901) for transforming a plain text, transforming process b(904) for untransforming a cipher key, and lastly untransforming process(916) are additionally executed. The transforming process a(901) transforms a plain text so as to later process the transformed plain text and so as not to process the plain text itself by the IP process(902) and f function process(903). Data of the plain text therefore becomes hard to be presumed from the current wave shape during the data process. The transforming process b(904) transforms a cipher key so as to later process the transformed cipher key and so as not to process the cipher key itself by the PC-1 process(905), LS process(907), PC-2 process(908) and f function(903). Data of the cipher key therefore becomes hard to be presumed from the current wave shape during the data process.
