All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The method aims to overcome the defects that enough security measures such as security operation passwords are not available when the hot wallet and the cold wallet are mutually converted, and the like, which are ubiquitous at present, and better process the mechanical rationality of hardware interchange. The embodiment provides a complete equipment system, which comprises a cold-hot wallet system matched with hardware and software. This cold wallet uses android system and hard key, when needs and hot wallet butt joint, through hard key and the two-dimensional code scanning of system to the high in the clouds, can automatic intelligent judgement running environment whether have the Trojan that is invaded and steal the number procedure at that time to need through the special professional protection password of multiple to digital general evidence, the user just can dock cold wallet and get into hot wallet operation interface, and carry out data updating automatically.
Fig. 1 shows a schematic diagram of a system using a cold wallet and a hot wallet according to the present embodiment. Referring to fig. 1, the system according to the present embodiment includes a warm wallet device 100, a cold wallet device 200, a remote platform 300, and a terminal device 400. Wherein the hot wallet device 100 can communicate with the remote platform 300 through a network, and the cold wallet device 200 can be connected with the hot wallet device 100.
In which fig. 2 shows a schematic view of the warm wallet device 100 and the cold wallet device 200 according to the present embodiment. Wherein the hot wallet device 100 may be a NAS (network attached storage) device connected to the internet. Referring to fig. 2, the hot wallet device 100 includes: display screen 2, hard disk 3, Window mainboard 4, android system mainboard 5, access 6 and the USB access 7 of hard key that connects.
The cold wallet device 200 includes: hard key 10, mainboard 11, display screen 12, camera 14 and solid state disk 15.
Wherein the cold wallet device 200 may be connected to the hot wallet device 100 by inserting the hard key 10 into the hard key access port 6 of the hot wallet device 100 (see fig. 4). Alternatively, the hard key 10 may be inserted into the rear insertion port 9 of the USB adapter (see fig. 3), and then connected to the hot wallet device 100 by inserting the USB interface 8 of the USB adapter into the USB access port 7 of the hot wallet device.
We illustrate the uniqueness of the cold wallet device 200 with the hot wallet device 100 as a NAS: the cold wallet device 200 has both a "hard" interface to a hard key that connects to the hot wallet and a set of identical "soft" interfaces to the matching digital pass-through client password. After the cold wallet device 200 is correctly inserted into the hot wallet device 100, a third-party device (i.e., a terminal device 400), such as a mobile phone, is used to enter the two-in-one digital certificate-passing transaction center system after the confirmation of the two-dimensional code is performed.
In the transaction, the system is interfaced with a professional algorithm aiming at digital evidence, and the transaction operation is started. The cold wallet device 200 may also be prompted for confirmation of the transaction before the final step of the transaction is completed, "the transaction has reached the final step and the cold wallet is requested to be dialed after final confirmation". When the user dials out the cold wallet device 200, the link of the cold wallet device 200 and the hot wallet device 100 is completely physically disconnected. The data thus completed for the transaction is stored in the cold wallet device 200 in a secure environment isolated from the network.
Further, although not shown, a processor connected to a display screen and an interface of each is provided in each of the hot and cold wallet devices 100 and 200.
Fig. 5 shows a flowchart of a pairing operation for achieving first pairing of the hot wallet device 100 and the cold wallet device 200 when the cold wallet device 200 is inserted into the hot wallet device 100 for the first time, and as shown in fig. 5,
first, the hot wallet device 100 detects whether the inlet 6 or the inlet 7 is connected to the cold wallet device (S502).
The hot wallet device 100, in the case of detecting that the inlet 6 or the inlet 7 is connected to the cold wallet device 200, determines whether the cold wallet device 200 is a cold wallet device to which the hot wallet device is connected for the first time (S504).
In the case where it is determined that the cold wallet device is the first connected cold wallet device, the cold wallet device is registered (S506). Specifically, for example, the display screen 2 of the hot wallet device may automatically jump out of a prompt box (see 42 in fig. 6), and the user fills in the self-defined password (see 41 in fig. 6) once and fills in the same determined password (see 43 in fig. 6), and then generates and stores the private key in the hot wallet, thereby completing the registration process.
The hot wallet device 100 then transmits first confirmation information indicating that the cold wallet device 200 has been registered to the cold wallet device 200 (S508).
Meanwhile, the cold wallet device 100 detects whether the hard key 10 is connected to the hot wallet device 100 (S510).
The cold wallet device 200 determines whether the hot wallet device 100 is a hot wallet device to which the cold wallet device 200 is first connected, in case that it is detected that the hard key 10 is connected to the hot wallet device 100 (S512).
In the case where it is determined that the hot wallet device 100 is the first connected cold wallet device, the first confirmation information is received from the hot wallet device 100 (S514).
Then, the cold wallet device 200 generates a two-dimensional code based on the received first confirmation information (S516).
Then, the terminal device 400 scans the two-dimensional code generated by the cold wallet device 200 and transmits the read two-dimensional code to the remote platform 300 for confirmation (S518).
The remote platform 300 then receives the two-dimensional code transmitted by the terminal device 400 and authenticates the two-dimensional code (S520).
The remote platform 300 then transmits the confirmation information that the cold wallet device 200 passes the authentication to the hot wallet device 100 (S522).
The hot wallet device 100 receives the confirmation information and transmits the confirmation information that the cold wallet device 200 passes the authentication to the cold wallet device 200 (S524).
Finally, the cold wallet device 200 receives the confirmation information from the warm wallet device 100. Thereby completing the entire first pairing operation (S526).
Thus, through the above flow, the first pairing operation of the cold wallet device 200 and the hot wallet device 100 is completed.
Then, when the cold wallet device 200 is inserted into the inlet of the warm wallet device 100 for the second time, that is, in a case where neither the cold wallet device 200 nor the warm wallet device 100 is connected to the other for the first time, the cold wallet device 200 issues an authentication request requesting authentication to the hot wallet device 100. The hot wallet device 100 performs an authentication operation after receiving the authentication request. Specifically, the method includes displaying only a prompt box 41 (see fig. 7) for filling in the password on the display screen 2, and then securely logging in the work interface after the correct password is filled in.
In addition, as shown in fig. 8, the cold wallet device and the hot wallet device described in this embodiment also jointly form a security authentication system with a private key corresponding to an address.
In the security authentication system shown in fig. 8, the cold wallet side 26 (corresponding to the cold wallet device 200) generates private key information 27 and then transmits the private key information to the hot wallet side 21 (corresponding to the hot wallet device 100).
The cold wallet side 26 then generates private key generation information 28 from the private key information 27, and the hot wallet side 21 generates address generation information 22 from the private key information 27.
The cold wallet side 26 generates a private key 30 from the private key generation information 28, and defines this private key 30 as the i-th private key 31 using the number i generated by the counter 29 in the cold wallet side 26.
The hot wallet side 21 generates an address 24 from the address generation information 22, and defines the address 24 as an i-th address 25 using a number i generated by a counter 23 in the hot wallet side 21.
So that for each private key in the cold wallet side 26, the hot wallet side 21 has an address corresponding to it.
Specifically, for example, an ESCDA algorithm may be used. Typically, an ECDSA private key is a random number x, and its corresponding public key is g ^ x. To generate a hierarchical deterministic key, it requires two more random numbers k and y.
The corresponding private key generation information is: k, x, y;
the corresponding ith private key is: x ═ y + H (k | | i);
the corresponding address generation information is: k, g ^ y;
the corresponding ith public key is: g ^ (xi) ═ g ^ (H (k | | i)). g ^ y;
and the corresponding ith address is: h (g ^ (xi)).
The cold wallet side 26 may also store information and address generation information which is then transferred to the hot wallet once. This information generates addresses in order when the hot wallet is to transfer data to the cold wallet. After the cold wallet is connected to the network, this information will also generate addresses in order, and the user can then view the corresponding addresses and their corresponding amounts.
Thus, the hierarchical deterministic wallet described above provides all the features we need: both hot and cold parties can generate a sequence of public/private keys, and these public/private keys are paired with each other (since the public key corresponding to the private key is g ^ x). When the hot wallet is not cracked, the public keys are mutually independent and can not be distinguished from each other, and whether the public keys come from the same address generation information or not can not be distinguished.
So that a secure transaction operation can be achieved with the cold wallet device 200 using the private key in the cold wallet device 200 and the public key and address in the hot wallet device 100 as described above. Fig. 9 shows a flow chart for signing a transaction of the hot wallet device 100 by the cold wallet device 200. Refer to FIG. 9
First, the hot wallet device 100 generates an unsigned transaction, which is associated with an address (S802);
then the hot wallet device 100 generates transaction information to be signed corresponding to the transaction according to the address and the transaction (S804);
then, the hot wallet device 100 displays identification information (e.g., two-dimensional code 1) corresponding to the transaction information to be signed on the display screen 2 (S806);
then the terminal device 400 reads the identification information displayed by the hot wallet, thereby obtaining transaction information to be signed (S808);
the terminal device 400 transmits the transaction information to be signed to the remote platform 300(S810), and the remote platform 300 receives the transaction information to be signed (S812);
the remote platform 300 transmits transaction information to be signed to the cold wallet device 200(S814) and the cold wallet device 200 receives transaction information to be signed from the remote platform 300 (S816);
the cold wallet device 200 finds a private key corresponding to the transaction according to the information to be signed (S818);
the cold wallet device 200 signs the transaction information to be signed with the private key, generating signed transaction information (S820);
the cold wallet device 200 displays identification information (e.g., the two-dimensional code 13) on the display screen 12 according to the signed transaction information (S822);
the terminal device 400 reads the identification information on the cold wallet device 200 and acquires the signed transaction information (S824);
the terminal device 400 then transmits the signed transaction information to the hot wallet device 100(S826) and the hot wallet device 100 receives the signed transaction information (S828);
the hot wallet device 100 verifies the signature of the transaction information using the public key corresponding to the transaction (S830);
after the verification is passed, the hot wallet device 100 broadcasts the transaction to other nodes (S832).
Therefore, through the mode, the embodiment can provide intelligent operation for the transaction system of the user, encrypt and quickly disconnect the network function, simultaneously can quickly connect to the network in an interface mode, and can instantly and automatically update data intelligently to immediately perform transaction.
