摘要： PROBLEM TO BE SOLVED: To provide a side-channel evaluation device and a side-channel evaluation method by which time required for tolerance evaluation of an encryption device against illegal decryption can be shortened.SOLUTION: While supposing that an operator performing safety evaluation of an encryption device 2 knows an encryption key of the encryption device 2, a true encryption key Ktr is input to an encryption key input part 6 of a side-channel evaluation device 1. A partial key calculation part 8 calculates a partial key k necessary for each selection function from the true encryption key Ktr. A selection function control part 7 selects a selection function for performing evaluation from a selection function database 9 and inputs the partial key k and measured encryption data Den to the selected selection function to cause the selected selection function to execute calculation. A correlation calculation part 10 calculates correlation between measured side-channel information Dsc and a selection function output H. When a correlation coefficient ρ is a threshold ρk or more, the selection function is output from an output part 12. The evaluation is executed in each of the selection functions stored in the selection function database 9.

摘要： PROBLEM TO BE SOLVED: To provide an authentication system that can be used continuously without requiring users to reacquire root certificates even if the service of a first certificate authority is stopped.SOLUTION: An individual certificate authority 3 is disposed separately from a commercial certificate authority 2 so that the individual certificate authority 3 issues a root certificate Tx to an authentication entity 4. The individual certificate authority 3 issues a commercial certificate authority public key Ka acquired from the commercial certificate authority 2 to the authentication entity 4 as a commercial certificate authority public key certificate Ta. The authentication entity 4 verifies the certificate Ta via the root certificate Tx and trusts the public key Ka if the verification is successful. The commercial certificate authority 2 issues an authenticated entity public key certificate Tb2 to an authenticated entity 5. When acquiring the certificate Tb2, the authentication entity 4 verifies it via the public key Ka and trusts an authenticated entity public key Kb2 if the verification is successful.

摘要： PROBLEM TO BE SOLVED: To provide a side channel evaluation device and a side channel evaluation method which can shorten the time of resistance evaluation for unauthorized decryption of an encryption device.SOLUTION: In the selection function database 9 of a side channel evaluation device 1, a plurality of selection functions used for calculation of fragility evaluation are registered. The selection function in the selection function database 9 is a selection function with a partial key k less than 16 bites, out of all selection functions AES-128 that must be confirmed under conditions that the implementation information is unavailable. A selection function with a partial key k of less than 16 bites becomes a use function because a selection function with a partial key k of more than 16 bites has high resistance against attack, because full number search of encryption key is an efficient attack method, and evaluation by a selection function with less than 16 bites is adequate or enough.

摘要： PROBLEM TO BE SOLVED: To provide an electronic key registration system capable of performing a key registration with high security even in an off-line area where no network connection can be established.SOLUTION: When a vehicle 1 is in an off-line area where network communication is unavailable, the vehicle 1 creates a ciphertext Dcr by combining a random number and an owner ID and passing it to an on-vehicle apparatus center key Kvc. A registered worker transmits an on-vehicle apparatus ID and the ciphertext Dcr as registration requirement information S1 to a center 25 by a letter, a phone, or the like. The center 25 decrypts the registration requirement information S1 by the on-vehicle apparatus center key Kvc at the center 25 and confirms the owner ID in the registration requirement information S1. When it is a normal owner, a response code is transmitted as registration approval information S2 to the registered worker by a letter, a phone, or the like.
