The corresponding system comprises these modules for former operation. This invention can prevent distorting the digital signature or code, and improves the security for intelligent key device greatly.
Description
Technical field
The present invention relates to information security field, particularly a kind of method and system that improves safety of intelligent key equipment.
Background technology
Intelligent cipher key equipment is a kind of small hardware device that has processor and memory, and it adopts the double factor authentication pattern, and use is simple, cost is lower.Its built-in single-chip microcomputer or intelligent card chip can be stored user's key or digital certificate, utilizes the authentication of the built-in cryptographic algorithm realization of intelligent cipher key equipment to user identity.That intelligent cipher key equipment has is E-mail enciphered, digital signature, safety certificate, secure network login and visit SSL (Security Socket Layer, the secure socket layer protocol layer) function such as secure network, and has the feature that the private key that guarantees the user leaves hardware never, also have the characteristic of attack protection physically, fail safe is high.
Intelligent cipher key equipment uses encryption usually or comes identifying user identity based on the digital signature of public key system, and the digital signature of public key system had both guaranteed the confidentiality of information, and the information that guaranteed again has non repudiation.The principle of using digital signature to verify is: at first with being verified the private key for user signature expressly, obtain digital signature, then digital signature is sent to authentication, authentication is decrypted with the PKI that is verified the user, and last and original text compares, and verifies.Data length to the need signature during digital signature is conditional, earlier the plaintext of needs signature is carried out HASH (Hash) computing usually so be verified the user, the HASH value is imported in the intelligent cipher key equipment signed then.The HASH algorithm also claims one-way Hash algorithm, is meant under the situation of known operations result and algorithm the algorithm that can not backwards calculation goes out raw information.Hash algorithm all can produce the output of regular length to the input information (being commonly called as seed) of different length.
Said process need can not guarantee the fail safe of digital signature or enciphered data fully, because also there is potential safety hazard in computer itself, for example, when computer has suffered trojan horse, need digital signature or ciphered data to be distorted by the bottom wooden horse, be transferred to intelligent cipher key equipment then and carry out digital signature or encryption, whether the user can't judge in the intelligent cipher key equipment needs digital signature or ciphered data correct, this has had a strong impact on the fail safe of intelligent cipher key equipment, make intelligent cipher key equipment lose the value of its existence, simultaneously, also will inevitably bring unnecessary loss to the user.
Voice technology has been applied in the intelligent cipher key equipment at present, mainly as prompt facility, for example, the prompting of greeting information, operation prompt information, fault alarm, affirmation input, read-write operation indication or the like.

Embodiment one
Identification authentication mode in the present embodiment is the PIN code authentication mode, needing digital signature or ciphered data is the information (as Bank Account Number, trade date, dealing money or the like) that the user need conclude the business, the user imports in the intelligent cipher key equipment by the information that computer will need to conclude the business, and, confirm the data that the intelligent cipher key equipment phonetic rehearsal goes out by the input unit on the intelligent cipher key equipment (as single button).
Referring to Fig. 1, the embodiment of the invention provides a kind of method that improves safety of intelligent key equipment, specifically may further comprise the steps:
Step 101: the user is connected to client computer with intelligent cipher key equipment;
Step 102: the user imports PIN code;
Step 103: whether the PIN code of intelligent cipher key equipment checking user input is correct, if correct, then execution in step 105, if incorrect and number of retries is full, then execution in step 104;
Step 104: the user is the disabled user, and intelligent cipher key equipment prompting error message finishes then;
Step 105: the user confirms as the legal holder of intelligent cipher key equipment by authentication, and client computer receives the information that the needs of user's input are concluded the business, and this Transaction Information is transferred in the intelligent cipher key equipment;
Step 106: intelligent cipher key equipment is resolved it after receiving the next data of client computer transmission, obtains critical data, and this critical data of phonetic rehearsal; This critical data is the part in the client computer transmission data of coming, data that can the representative of consumer input; For example, the data of user's input are: address name, Bank Account Number, trade date, transaction classification and dealing money, and then critical data is: Bank Account Number, transaction classification and dealing money, these three data can be represented above-mentioned five data;
Step 107: the user judges whether the critical data of intelligent cipher key equipment phonetic rehearsal conforms to the information that need conclude the business, judge promptly whether the critical data of intelligent cipher key equipment phonetic rehearsal has represented the information that need conclude the business, if then execution in step 109, otherwise execution in step 108;
Step 108: the user cancels current operation, finishes then;
Step 109: the user is by the input unit on the intelligent cipher key equipment, and promptly single button to intelligent cipher key equipment input validation information, confirms that promptly the critical data of intelligent cipher key equipment phonetic rehearsal has been represented the information that need conclude the business;
Step 110: after intelligent cipher key equipment was received user's affirmation information, the information that the needs of above-mentioned user's input that transmission comes to client computer are concluded the business was carried out the HASH computing, obtains the HASH value;
Step 111: intelligent cipher key equipment utilizes private key that the HASH value is carried out digital signature, and by client computer digital signature is sent to server end;
Step 112: the public key verifications digital signature that the server end utilization is corresponding with above-mentioned private key, if the verification passes, then execution in step 114, otherwise execution in step 113;
Step 113: server end returns error message, and authentication failed is closed the trade then;
Step 114: checking is passed through, and finishes transaction.
Input unit in the present embodiment is that single button can be replaced by numerical key, sensor devices, fingerprint scanner, audio-switch, body temperature inductor, pressure inductor, vibrating sensor, acceleration transducer, magnetic sensors or electric field induction device.Carrying out the mode of authentication can be replaced by the mode that carry out authentication by the human body biological characteristics of verifying user's input by the PIN code of checking user input.
