摘要： An inter-equipment authentication and key delivery scheme, system, and equipment is provided which is capable of making authentication of an IC card ID signature, by comparison of a decrypted ICCID with another ICCID reproduced by dividing transmitted data. The inter-equipment authentication and key delivery scheme, system, and equipment can be used, for example, when an automobile passes by roadside equipment at a tollbooth, and the roadside equipment transmits a random digit (RND) generated therein as challenge data to an IC card via onboard equipment, and the IC card transmits back to the roadside equipment the random digit after encrypting it with a secret key Kicc. The IC card also transmits its ID (ICCID) and a certificate of individual IC card key CERT-Kicc together with the random digit. The roadside equipment divides the transmitted data into a response data E(Kicc, RND), the ICCID, and the certificate of individual IC card key CERT-Kicc. The roadside equipment 130 reproduces the Kicc and the ICCID by decrypting (DEC) the certificate of individual IC card key CERT-Kicc using a validation key PC.

摘要： PROBLEM TO BE SOLVED: To provide a system and a method for ETC authentication which enable a roadside machine and a central processing unit to directly authenticate the legitimacy of an IC card. SOLUTION: When a vehicle passes by a tollgate roadside machine 13, response data stored on an IC card 11, namely, a random number generated by the roadside machine 13 when passing by the roadside machine 13 is transmitted to the IC card 11 as challenge data through an on-vehicle device 12, and the data after being enciphered by a regular secret key Kicc is sent to the tollgate roadside machine 13. At this time, the ID (ICCID) of the IC card 11 and an IC card individual key certificate CERT-Kicc are both sent to the roadside machine 13. The roadside machine 13 divides the sent data into three, i.e., the E as response data (Kicc, RND), the ICCID and the IC card individual key certificate CERT-Kicc. Here, IC card individual key certificate CERT-Kicc is decoded (DEC) with a verifying key PC and then pieces of information which are Kicc and ICCID can be extracted. This ICCID is compared with the ICCID which is divided and taken out as mentioned above to decide their matching and when they do not match each other, the signature of the IC card ID is confirmed.

摘要： PURPOSE:To make a user correctly judge by a method wherein the current position is forecast to evaluate errors in the forecasting and the range thereof is limited from information obtained even when the measurement of the current position becomes impossible. CONSTITUTION:When it is judged that necessary satellites for the decision of position are all set, from measuring data of a plurality of satellites demodulated by a receiver 1, the current position and speed are calculated by performing a position measuring computation from a judgement data. Then, when it is judged that the satellites necessary for the limiting to an area between two straight lines are all set, an existence area between the two straight lines of a moving object is calculated using the measuring data. The time elapsed to the measurement of the area from the newest measurement of positions is measured by a timepiece 2. Then, the maximum moving area (area b) of the moving object is calculated 3 when the object is accelerated to the maximum speed at the maximum acceleration for the time elapsed using the position (area a) and the speed obtained by the newest position measuring computation as initial value. Then, an area common to the areas (a) and (b) is determined and the existence range of the moving object is limited to the area to display 4.

摘要： PURPOSE:To shorten the talk time with and enhance the secrecy of a differential GPS position measuring device using telephone circuit. CONSTITUTION:From a mobile station side transmit/receive part 12, a mobile station gives a signal transmit request to a base station side transmit-/receive part 6 by issuing a correction error request at any time desired by the user, and a talk is commenced. By an encoding part 4, the base station having received the transmit request encodes the error information at the time under control of a transmit control part 5 and transmits from the transmit/receive part 6. The mobile station receives the encoded error information via the mobile station side transmit/receive part 12, interpreting the code by a code interpreting part 13 after the end of the talk, and corrects the position measuring position which is calculated as the correction data from the satellite track data by a correction position sensing part 14. Thereby high precision position measuring can be done with secrecy.
