example 1

[0108] FIG. 1 is a block diagram of an advanced authentication system 1 according to a first example of the present invention. FIG. 1 also shows a flowchart describing the operation of the elements of the advanced authentication system 1 .

[0109] Advanced authentication system 1 comprises: remote server 2, main frame (or personal computer) 3, card reader / recorder 4, have the electronic seal 5 of the authentication function that utilizes secret key, have and secret key form key pair The card 6 and the input device 31 for the verification function of the public key. The card reader / writer 4 functions as an input / output section as a communication interface between the electronic seal 5 and the card 6 . The card 6 is a removable storage medium (contact type, portable storage medium), for example, an IC card or a memory card.

[0110] The remote server 2 has various card-related information stored as a backup.

[0111] When instructed by the input device 31 , the host 3 issues...

example 2

[0202] In the first example, an advanced authentication system 1 including an electronic seal 5 and a card 6 is described. In a second example of the present invention, a description will be given of a multimodal advanced authentication system including a multimodal electronic seal and a multimodal card for performing multimodal advanced authentication providing more functions.

[0203] FIG. 7 is a block diagram illustrating a multimodal advanced authentication system 10 according to a second example of the present invention. FIG. 7 also shows a flowchart describing the operation of elements of the multimodal advanced authentication system 10 . The same elements as those in FIG. 1 share the same reference numerals, and their detailed descriptions are omitted.

[0204]The multi-mode advanced verification system 10 includes a remote server 2, a host computer (or personal computer) 3, a card reader / recorder 4, a multi-mode electronic seal 7 with a verification function using a s...

Abstract

An electronic seal includes an input / output section for receiving a random number encrypted based on a prescribed key; and an advance authentication processing section for decrypting the encrypted and received random number based on a secret key related to the prescribed key and then encrypting the decrypted random number based on the secret key. The input / output section outputs the encrypted random number encrypted based on the secret key.

Description

technical field [0001] The present invention relates to an electronic seal and a storage medium, such as an IC card and a memory card, for example, used in a city office for direct transaction services between buyers and sellers and in electronic commerce, for authentication; An advanced authentication system using the electronic seal; and a mobile device, a portable telephone device, and a vehicle engine control device accommodating the electronic seal. Background technique [0002] Traditionally, seals (traditional seals) have been used to authenticate services and business transactions conducted at city offices for direct transactions between buyers and sellers. When a seal is stolen or lost for some other reason, the user can easily notice the loss and be able to take precautions against any possible damage. [0003] Recently, for example, information in the form of electronic data (digital data) has started to be used in IC cards, identification cards, electronic comme...
