It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. 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.
The invention relates to a safe storage device which is used for binding hardware resources of a storage device by adopting an encrypted storage device on a mobile storage device and needs to unlock a safe storage space on the encrypted storage device through a special command interface. The storage space in the encrypted storage device is divided into 2 parts, and one part is reserved for a boot startup program which provides an interface for unlocking other storage spaces. The other part is a safe storage area which stores the safety data of the user and comprises an operating system. And when the boot program is started, receiving unlocking information of a user, pairing the unlocking information with the binding information in the storage equipment, if the pairing is correct, quitting the boot program, hiding a storage area where the boot program is located, unlocking the secure storage area, restarting the system, and rebooting and starting from the secure storage area. The storage device includes, but is not limited to, a storage medium such as an HDD, SSD, etc.
As shown in fig. 1, one is a boot area 11, which is visible when the host is started, and the other is a secure storage area 12, which is not physically visible, and data in the secure storage area cannot be read or written by any command. After the safe storage area 12 is unlocked, when the system is not powered off, that is, under the condition that the storage device is not powered off, the storage device always works in the safe storage area 12, and only when the host is powered off and is started again, the safe storage area 12 is actively hidden, and is switched to the boot area 11, and the storage device is booted again to unlock.
Fig. 2 is a flowchart of a method for secure storage of a storage device according to an exemplary embodiment of the present invention, including:
s202: receiving an unlocking instruction which is sent by a host and used for unlocking a safe storage area of the storage equipment;
s204: when the unlocking instruction passes the verification, unlocking the safe storage area;
s206: and returning an unlocking success instruction to the host.
The host comprises electronic equipment such as a portable computer, a desktop computer and a mobile terminal, unlocking the safe storage area comprises setting an unlocking mark, hiding a guide area of the storage equipment and unlocking the safe storage area.
Specifically, the host sends a self-defined command for unlocking the secure storage area to the storage device, data in the data is encrypted by using a random number, namely a private key, recorded during authentication, the storage device unlocks by using the random number, namely the private key, recorded during authentication after receiving the unlocking command, whether the command data is correct is checked, and if the command data is correct, unlocking is performed, an unlocking mark is juxtaposed, the boot area is hidden, and the secure storage area is unlocked. The unlock mark can be distinguished by setting an identifier, and the address range of the secure storage area, such as 0x1000-0x1 fffffff, is mapped to the logical address 0x0000-0x1effff of the storage device, and the address range 0x0000-0xffff of the boot area is shifted out of the address range of the storage device to hide the boot area. The host sees a physical disk with an address range of 0x0000-0x1 effff. After the host receives the successful state of the unlocking command, the information of the storage device is refreshed, the system can also be started in a hot mode, at the moment, a boot area of the host is not seen, only a safe storage area can be seen, and the safe storage area is a normal storage device for the host and can perform normal partitioning, formatting, reading and writing and other processing.
In another exemplary embodiment of the present invention, before the receiving an unlocking instruction sent by a host to unlock a secure storage area of a storage device, the method further includes: receiving an authentication instruction for reading the feature information sent by the host, encrypting the feature information and the generated random number and returning the encrypted feature information and the generated random number to the host; and receiving and decrypting the preprocessed feature information and the preprocessed random number, verifying whether the feature information and the preprocessed random number are correct or not, and returning an authentication success instruction when the feature information and the preprocessed random number are verified to be correct.
Before the boot program completes the communication between the storage device and the host, authentication processing needs to be performed, and the authentication flow is shown in fig. 3:
s301, the host sends a special command to the storage device;
s302, reading a specific information word and a group of random numbers of the storage device, encrypting the data by using an agreed public key and then sending the encrypted data to a host for reading;
s303, the host decrypts by using the public key, checks whether the specific information words are matched, if not, the authentication fails, otherwise, the random number is recorded, predefined processing is carried out on some data in the group of data (such as changing the position of the random number, negating some data and the like), and the data is encrypted by using the public key and then sent to the storage device; the preprocessing comprises AES, SM4, DES and other algorithms.
S304, the storage device decrypts after obtaining the data and checks whether the group of data is correct, if the data is correct, the authentication is successful, the random number is recorded as a private key, the writing success state is returned to the host, and if the data is not correct, the failure state is returned to the host.
S305, after the host computer reads the success state, the authentication is finished, the recorded random number is also used as a private key, and the private key is used for carrying out encryption and decryption processing on command data in subsequent commands.
After the authentication is finished, the host reads the configuration data encrypted by the private key, the data comprises bound host hardware information, the host reads the current hardware information and compares the current hardware information with the bound information in the read hardware information, the next operation of unlocking the safe storage area can be carried out only if the comparison information is consistent, otherwise, the safe storage area cannot be unlocked. The hardware information of the host is bound through the storage device with hardware encryption to ensure the security of the data stored in the storage device, wherein the storage device comprises but is not limited to a domestic storage device. Because the storage equipment is bound with the computer storage equipment resources, the storage equipment is disassembled and installed on other computers and cannot run, and compared with the prior art, the method has the advantages that the binding and cracking probability of hardware resources is not reduced, and the safety performance is improved.
The read-write command in the authentication process is a storage device manufacturer self-defined command, the data content is also self-defined, and the read-write command is encrypted in the transmission process so as to ensure that the authentication process is not decoded and the data safety of the storage device is ensured.
When the storage equipment is powered off, the storage equipment can automatically enter a locking state, namely the guide subarea is visible and the safe storage area is invisible, and after the storage equipment receives a power-off signal, the storage equipment can be locked through a hardware switch of the storage equipment. Normal reading and writing can be carried out on the safe storage area of the storage device only by re-authenticating and unlocking the safe storage area.
The safe storage partition can be divided into a plurality of partitions according to the needs of users, an unlocking password is set for each partition, and an unlocking password can be set for a plurality of connected partitions. After that, the host can see a normal working disk with the capacity of one or a plurality of continuous partitions by refreshing the information of the storage device, and other safe partitions are continuously processed in a hidden state, so that a user cannot read and write the hidden partitions.
In the above exemplary embodiments of the present invention, the boot start program is installed in the boot area, and is used to detect whether the hardware in the host is consistent with the binding information in the storage device, if not, the host stops working, otherwise, an unlock secure storage area password input window is popped up, and a user is required to input an unlock password, when the password is correct, the secure storage area is unlocked, and the boot area is hidden, and at this time, the host can see all the information in the secure storage area, and can perform normal read-write operation as in a normal storage device.
