Safety device for identifying cipher and safety identifying method

Abstract

The present invention relates to a kind of security device for identifying code, which stores multi-identifying codes. The server terminal is calculated through a pre-designed formula and disperses the outgoing enquired address into a numerical value, which is larger than that of the indexed information of the address. After incoming the security device, an identifying code obtained by a processing unit decipher is sent out. Through a broad increase of the transmitted numerical value of the indexed information, the malicious intruder wrongly judges the indexed information as a true address, thus enhancing the difficulty of the decoding and reducing the possibility of the intruding.

Description

Technical field: [0001] The invention relates to an identification password security device, in particular to an identification password security device that disperses the storage address of the identification password through a predetermined formula calculation and improves the difficulty of malicious intrusion and cracking. Background technique: [0002] According to the news announced by the police, once the homeowner replaces the door lock with a more difficult-to-break high-level lock, the household’s theft rate will drop significantly. That is to say, the thief judges that the time cost of the intrusion has increased and the risk of being cracked has increased, and that the household is not worthy of intrusion, and changed to steal from other people with lower intrusion costs. Such criminal psychology also exists in the online world. [0003] Due to the convenient network transmission, the speed of information transmission is increasing day by day, regardless of financial-r...

Problems solved by technology

[0008] Of course, increasing the number of identification passwords in a large amount, for example, increasing the identification passwords arranged by 30,000 sets of random numbers to 3 million sets can achieve the effect of reducing the risk of fraudulent use, but this method not only causes each encryption machine The cost of medium memory increases, or the length of the password card is greatly expanded, which is not conducive to carrying, especially considering that financial institutions must face tens of thousands or even millions of customers. When the password of each customer increases by a hundred times, the financial institution itself The database capacity will also be greatly doubled accordingly, and the skyrocketing cost will inevitably deter financial institutions, leaving room for further improvement in the security of this solution
