Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Fig. 1 is a method flow diagram of the blockchain cold wallet based transaction method of the present invention. In step S1, a non-networked wallet server to which a first scanning device and a first display device are attached and a networked wallet server to which a second scanning device and a second display device are attached are configured. In a preferred embodiment of the invention, the non-networked wallet server may be any server that is not able to communicate with the external internet in any way. Therefore, the first scanning device and the first display device mounted thereon can only communicate through the USB interface connector directly connected thereto. The first scanning device and the first display device cannot be networked. The networked wallet server is responsible for local private key storage. Because the private key cannot be connected with an external network, the local private key cannot be in contact with the network, and the security of the private key can be ensured. The networking wallet server is connected with an external network through a blockchain. The second scanning device and the second display device, which are additionally installed thereon, may communicate through a USB interface connector directly connected thereto, and may also communicate therewith through the internet. Preferably, the first and second scanning devices may be code guns, and the first and second display devices may be liquid crystal displays. The first scanning device is arranged right opposite to the second display device, and the second scanning device is arranged right opposite to the first display device.
In step S2, the networked wallet server receives transaction data to be signed from the internet, encodes the two-dimensional code, encrypts the obtained two-dimensional code with a public key, and displays the encrypted two-dimensional code on the second display device. In a preferred embodiment of the present invention, the networked wallet server may encode the obtained transaction data into a two-dimensional code that may be displayed by a display device using any known encoding method. Further, any encryption method may be used to encrypt the obtained two-dimensional code. For example, common DES and RSA hybrid encryption algorithms may be employed. Preferably, the encrypted two-dimensional code is updated and displayed, for example, at set time intervals.
In step S3, the first scanning device scans and obtains the encrypted two-dimensional code, the non-networked wallet server decrypts the encrypted two-dimensional code using a local private key to obtain the transaction data and signs using the local private key, then two-dimensional code encoding is performed on the signed data to generate a signed two-dimensional code, and the first display device displays the signed two-dimensional code. Preferably, the first scanning device may scan and acquire the encrypted two-dimensional code in a timed polling manner. Of course, in another preferred embodiment of the present invention, the first scanning device may also maintain the scanning device all the time, so as to acquire the two-dimensional code at the first time. Preferably, in this step, the two-dimensional code may be encrypted once more. In this step, the first scanning device can only obtain the encrypted two-dimensional code by means of two-dimensional code scanning, and transmit the encrypted two-dimensional code to the non-networked wallet server through the USB interface connector. After the non-networking wallet server generates the signature two-dimensional code, the first display device can only obtain the signature two-dimensional code through the USB interface connector. Thus ensuring the safety of the whole process.
In step S4, the second scanning device scans and acquires the signature two-dimensional code to obtain the signature data, and then the networked wallet server broadcasts the signature data through a blockchain. In this step, the second scanning device scans the signature two-dimensional code by a timed polling method. In another preferred embodiment of the present invention, the second scanning device may also keep the scanning device all the time, so as to acquire the two-dimensional code at the first time. In this step, the second scanning device can only obtain the signed two-dimensional code by means of two-dimensional code scanning, but cannot communicate with the non-networked wallet server by means of other methods, so that the security of the whole process is further guaranteed.
According to the transaction method based on the block chain cold wallet, the public key of the networking wallet server is used for encryption, and the private key of the non-networking wallet server is used for decryption and signature, so that the encryption process is complex, the safety degree is high, and the networking wallet server and the non-networking wallet server can only perform scanning communication through two-dimension codes, so that the safety is further improved. Furthermore, by arranging the two scanning devices and the display device, the scanning display can be automatically carried out, so that the automation degree is high, and the use is convenient.
