Fig. 2 is a kind of digital asset secure storage means structural schematic diagram provided in an embodiment of the present invention.
Specific embodiment
The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention..
Embodiment 1
The embodiment of the present invention 1 provides a kind of method flow schematic diagram of digital asset secure storage.Specifically such as Fig. 1 institute
Show, digital asset is stored in digital wallet, is stored in client identification module SIM card with the public key in digital wallet counterpart keys
In, private key corresponding with public key is stored in near-field communication NFC label.This method is mainly used in a kind of digital asset safety
Storage tool, the secure storage means are installed in the intelligent terminal with near-field communication FC function.This method may include:
Step 110, the operational order of user's input is received.
Step 120, according to operational order, indicating intelligent terminal reads public key from SIM card, or reads from NFC label
Private key.
Step 130, it according to public key or private key, executes and operational order corresponding operation.
Optionally, corresponding operation includes at least: checking assets information or signs to Transaction Information.Certainly,
It can be other operations, concrete operations content can be defined according to the actual situation, not do excessive restriction here.
And when operational order is used to indicate and checks assets information, then indicating intelligent terminal reads public key from SIM card.Step
Rapid 130, it specifically includes: public key is sent to digital asset platform, when legal so as to digital asset platform validation public key, feedback money
Information is produced to check for user.
Specifically, (OMA in NFC can be referred specifically to assist according to NFC protocol there are the intelligent terminal of NFC function
View), public key is read from SIM card.Public key is sent to digital asset account platform by digital asset secure storage means, works as number
When asset account platform determines that public key is legal, then will corresponding with public key assets information (may include current assets remaining sum with
And transaction record etc. information) feed back to intelligent terminal after be shown, in order to which user checks.
And when operational order is used to indicate and signs to Transaction Information, then indicating intelligent terminal is read from NFC label
Take private key.
Step 130, it specifically includes: being signed according to private key to Transaction Information.
Specifically, by NFC label close to the intelligent terminal with NFC function after, intelligent terminal read private key；Then it sends
To digital asset secure storage means.
Digital asset secure storage means recycle private key to sign Transaction Information.
It optionally, further include account address in SIM card, in NFC label further include: mnemonic word and cipher key store keystore letter
Breath.
In fact, account address is played the role of and public key effect is same or similar.And mnemonic word and cipher key store
Keystore information is played the role of same or similar with private key, in above-mentioned steps, public key can be replaced with account
Address, or private key is replaced with into mnemonic word and cipher key store keystore information, and other methods step is identical.Therefore, here
It is no longer repeated.
Optionally, receive user input operational order before, this method can also include: according to NFC protocol, will be public
Key and account address are according to presetting format write-in SIM card；
And NFC label is written into private key, mnemonic word and keystore information, wherein account address is user in number
The account address that word assets platform generates after being registered.
A kind of method of digital asset secure storage provided in an embodiment of the present invention, public key are stored in SIM card, private key
It is stored in NFC label, so that key completely disengages intelligent terminal memory.Even if intelligent terminal is in network environment, illegal
Molecule can not also obtain key, therefore will not constitute a threat to the safety of digital asset.Still more, the aforesaid operations in the application
It is to be completed in the case where not contact network, therefore can guarantee the comparatively safe of digital asset.And works as and receive user
Operational order after, it is possible to determine that the operational order of user is that operation be used to indicate, and according to operational order, selection is from SIM
Public key is read in card, or after reading private key in NFC label, and then execute corresponding operation.
In addition, there is also following advantages: just because of public key and private key be respectively stored in SIM card and NFC label in.Cause
This, when intelligent terminal damages or replaces mobile phone, it is thus only necessary to which SIM card is inserted into other intelligent terminals with NFC function
In.It avoids since intelligent terminal damages or replaces intelligent terminal, needs again importing digital wallet backup file
Trouble.Assets information can be browsed at any time.And NFC label has storage time long, non-damageable speciality more ensure that number
The safety of word asset store.In addition, being written and read safely, quickly by the communication protocol of NFC to key in practical process.
