Fig. 2 is please referred to, Fig. 2 is a kind of NFC key cards configuration that equipment 100 is configured applied to NFC key cards shown in FIG. 1
The flow chart of method, below will be to the method includes each steps to be described in detail.
Step S110 generates the 1st of preset length according to the seed password generated at random and payment cipher input by user
Grade private key.
In the present embodiment, the NFC key cards configuration equipment 100 can receive branch input by user under off-line state
Pay password, and automated randomized generation seed password.Wherein, the seed password may include in English, Chinese or number
Any one or the combination between it.
In the present embodiment, after generating the seed password and the payment cipher, can according to the seed password and
The payment cipher generates the 1st grade of private key.
Further, in the present embodiment, the 1st grade of private is being generated according to the seed password and the payment cipher
After key, the 1st grade of public key is generated according to the 1st grade of private key.
Step S120 generates a kth grade random number at random, for each kth grade private key, according to the kth grade private key and
+ 1 grade of private key of kth of the kth grade generating random number preset quantity, wherein k is more than or equal to 1.
For example, city 2^32 the 2nd grade of private keys can be given birth to according to the 1st grade of private key and the 1st grade of random number, for each 2nd grade
Private key can generate 2^32 3rd level private key according to the 2nd grade of private key and the 2nd grade of random number generated at random, and so on,
Form the private key of multiple levels.
Further, in the present embodiment, default according to the kth grade private key and the kth grade generating random number described
After+1 grade of private key of kth of quantity ,+1 grade of public key of kth is generated according to+1 grade of private key of the kth.
The private key of all generations is stored in the encryption chip of the 1st grade of NFC key card by step S130, so that the described 1st
Grade NFC key cards can export wherein any one private key by NFC communication mode.
Further, in the present embodiment, all public keys of generation can also be stored in the 1st grade of NFC key card
Encryption chip in.
Based on above-mentioned steps, the 1st grade of NFC key card can be held by the highest user of permission, which can lead to
It crosses in 1 grade of NFC key card and manages all private keys, realize the administering of property that all private keys are corresponded to virtual token.
Different k+1 grade private keys are stored in different k+1 grade NFC key cards by step S140, and are directed to each k+1
Other private keys generated according to the k+1 grades of private key are stored in the corresponding k+1 grades of NFC key card of the k+1 grades of private key by grade private key
In, to keep+1 grade of NFC key card of kth private by exporting any one in+1 grade of NFC key card of the kth in a manner of NFC communication
Key.
Further, the corresponding public key of all private keys in the k+1 grades of NFC key card is stored in+1 grade of NFC key of the kth
In the encryption chip of card.
Based on above-mentioned steps ,+1 grade of NFC key card of the kth can be held by the leader user of the level, the user
It can be realized to all private keys pair under the branch by managing private key all under respective branches in the k+1 grades of NFC key card
Answer the administering of property of virtual token.
Further, in the present embodiment, there are one according to other opposite private keys of the private key for the private key correspondence each generated
Hierarchical relationship generate private key number, stored while store private key the private key private key number.In this way, needing to use
When private key is traded signature, it can be numbered by private key and search corresponding private key from NFC key cards.For example, the 1st grade of private key
It is denoted as m, the 2nd derived from grade private key is denoted as m/0 to m/2^32-1, and the private key that m/0 derives from is denoted as m/0/0 to m/
0/2^32-1。
Fig. 3 is please referred to, the present embodiment also provides another kind NFC cipher key configuration methods, below to each step of this method
It is illustrated.
Step S210 generates the 1st of preset length according to the seed password generated at random and payment cipher input by user
Grade private key.
This step is with step S110, and details are not described herein.
Step S220 generates a kth grade random number at random, for each kth grade private key, according to the kth grade private key and
+ 1 grade of private key of kth of the kth grade generating random number preset quantity, wherein k is more than or equal to 1.
This step is with step S120, and details are not described herein.
The 1st grade of private key and the 1st grade of random number are stored in the encryption chip of the 1st grade of NFC key card by step S230
In.
In this step, the 1st grade of private key and the 1st grade of random number are stored in the 1st grade of NFC key card, in this way, the
The holder of 1 and NFC key cards can manage the 1st grade of private key, and can the 2nd grade of private key of relatively independent generation, realize to next
Grade private key corresponds to the management and control of virtual token assets.
Different k+1 grade private keys are stored in different k+1 grade NFC key cards by step S240, and by+1 grade of kth with
Machine number is stored in+1 grade of NFC key card of kth.
In this step ,+1 grade of random number of+1 grade of private key of the kth and kth is stored in+1 grade of NFC key card of kth,
In this way, the holder of kth+1 and NFC key cards can manage+1 grade of private key of kth, and can+2 grades of privates of relatively independent generation kth
Key realizes the management and control that virtual token assets are corresponded to next stage private key.
Based on above-mentioned design, every grade of NFC key card can carry out the private key of oneself and the private key of respective branches next stage
Management.Each NFC key cards only store 1 private key and 1 random number, reduce the data storage capacity of NFC key cards.
