Step S303 recombinates the packet key after decryption, obtains the key；
Step S304 is signed using the transaction data that digital cash described in the key pair is traded, and completes digital goods
Coin transaction.
Dispersion can be stored in first terminal when user needs to carry out digital cash transaction through the embodiment of the present invention
Packet key in equipment and multiple second terminal equipment is recombinated, so that the key pair digital cash obtained using recombination is handed over
Easily sign.
On the basis of previous embodiment, if user has found that key is lost, in another embodiment of the present invention, such as Fig. 4
It is shown, the method also includes:
Step S401 receives the key recovery request of user's input, user itself life is carried in the key recovery request
Object identification feature；
Step S402 obtains the more of key to be restored in the first terminal equipment and multiple second terminal equipment
A packet key；
In the first terminal equipment and multiple second terminal equipment, the number of the packet key of key to be restored is obtained
Amount is at least n.
Step S403 is utilized respectively pre- imputation to each packet key using user's own biological identification feature
Method is decrypted；
In embodiments of the present invention, the preset algorithm is elliptic curve.
Step S404 recombinates the packet key after decryption, obtains the key.
Dispersion can be stored in first eventually in user's Lost Security Key, according to key recovery request by the embodiment of the present invention
Packet key in end equipment and multiple second terminal equipment is recombinated, to recover the key of loss
