Abstract

DC60 (29/05/41) for confirmation to be true. Using multiple secret cipher keys Time to verify it is original Will be shortened In case of the encryption key In order to encrypt the keys needed to access each area of the floor. Extension In the memory of the IC card, multiple areas Which access is communicated to the IC card from the writer and multiple cryptographic readers and keys. That correspond to these areas A decrypt key (for example, cryptographic key 1, cryptographic key 2, and cryptographic key 4) is read, and the mitigation process generates one decrypt key from those cipher keys. This is a random number which is generated from the given section. Stationery random number generator And read is transferred to the IC card, and the cryptographic part encrypts the random number using the decrement key, the writer and read receives the random number. That are encrypted from an IC card and decrypted Using the key for reducing the value And decide whether the IC card is suitable if the decrypted random number Is equal to a random number that has been born

Claims (5)

1. The system confirms that it is the original. For executing verifiable processing between the first device and Second device Where one such device will be involved Assembled as follows One memory mechanism to store a number of keys. First generating mechanism for generating verification keys. Whether to be the original one out of a reasonable number of keys from a number of keys One such device stored in the first memory mechanism and the one for communicating with the second and the second device. Which contains the following components A second memory mechanism for storing a number of keys. Second generating mechanism for generating keys to verify that Is a real one out of a reasonable number of keys It is stored in the first memory mechanism and the second communication mechanism for communicating with one such device from one device. And the second device sounds It has a cryptographic mechanism for encrypting using keys. To stand for the original and another device from one device. And the second device Which has a decryption mechanism For decrypting the information It is encrypted by the said cryptographic mechanism using a series for Confirm that it is the real one. 2. The system is authenticated according to claim 1, in addition, any device from the first and second device has a notification mechanism for Provide the information needed to generate the key to verify that Is the original corresponding one of the appropriate number of keys from Some of the aforementioned keys that are stored in it to the device. Another device and another device of the first device And that second device will generate a key to verify that Is the said person in accordance with the news Azimuth by the mechanism for informing them 3. The system confirms that it is the original according to claim 1, at least one such device And the second device sounds Any one of these has a random number generator. For generating random numbers with such a cryptographic mechanism to encrypt the meaning A random number generated by the said random number generator; and The decryption mechanism decrypts the random number that has been encrypted. 4. The system confirms that it is the original according to claim 1, where the second device has several areas for recording information that Corresponds to a number of the aforementioned keys 5. How to verify that it is the original for processing. To verify that it is the original between the first device and Second device Method in one such device It contains the following components: one memory step for storing a number of keys. The first procreation process for the birth of the keys for the stands. Confirm that it is the original one out of a reasonable number of keys from the key. A certain amount is stored in that memory phase. One of the aforementioned and a communication procedure one for communicating between the aforementioned two devices and a method on the aforementioned second device. It contains the following components: a second memory step for storing a number of keys. The second procreation process for giving birth to the keys for the stand. Confirm that it is the original one out of a reasonable number of keys from the key. A certain amount is stored in that memory phase. One such and a communication procedure the second for communicating between the devices. One such One device from one device And the second device sounds It is said that the cryptographic process is performed for the encryption using a key to verify that the original is and the other device from one device and the device.
