Description
Technical field
The utility model relates to a kind of safe storage device, specifically a kind of portable computer safe storage.
Background technology
Growing along with computer technology; the application of portable computer is more and more extensive; problem of data safety in storer constantly occurs; particularly in the portable computer of concerning security matters librarian use, storing a large amount of significant datas; if not protection; once lose, the leakage that can bring confidential information, brings about great losses.Safe storage for portable computer has adopted some safety encipher technology at present, or exists some potential safety hazards, or in ease for use, does not reach user's requirement, and subject matter comprises:
Adopt the method for software cryptography storer to have certain potential safety hazard, no matter in application layer or operating system layer, realize, hacker can crack software on system, and be difficult to realize the overall encryption that comprises disk boot sector, so software cryptography mode is compared with the cipher mode of realizing at hardware layer, security is lower.
Some safe storages are used master control to encrypt, by BIOS interface input user password, carry out authentication, the safety problem existing is exactly the storage mode of encryption key, at main control chip, there is certain potential safety hazard in key storage, once storer is lost, if hacker knows the memory location of key, can steal and crack.User's password mode is carried out the identification authentication mode of encryption and decryption, and user password is easily forgotten.
Other safe storages are used the mode of smart card to authenticate, by key storage in smart card, also some has adopted the keyboard USBKey device strengthened or touch panel device as authenticating device, yet these modes are often only applicable on movable storage device, to portable computer, need at counter body, open the interface of external unit, bring fringe cost.
Encrypting mobile memory has had all multi-products to adopt the authentication mode of radio-frequency card or smart card, security and ease for use improve, but the encrypting module of mobile memory in the market all adopts the low-speed interfaces such as USB, encrypting module enciphering rate is not high, can not be transplanted to the SATA interface internal memory of portable computer.So portable computer is badly in need of wanting good, the safe hardware level encrypted memory of a kind of ease for use.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of portable computer safe storage, and to achieve these goals, the utility model solves the technical scheme that its technical matters adopts and is:
A safe storage, comprises hard disk, embedded controller and encryption master control, also comprises power module, radio-frequency card reader and antenna; Hard disk is connected with encryption master control by SATA interface, and embedded controller is connected with power module with encryption master control, radio-frequency card reader respectively, and radio-frequency card reader is connected with antenna.Encrypt master control built-in encryption algorithm, disk read-write data are carried out to encryption and decryption, after radio-frequency card reader and antenna induction radio-frequency card, read user profile, on embedded controller, be built-in with TCM chip.
This programme also needs the built-in TCM chip-stored encryption key of main frame, in TCM, store in advance the encryption key of Dealing with encrypt code, the user profile that embedded controller plug-in is read by radio-frequency card reader, encryption key in embedded control device user decrypts information TCM is transferred to encryption master control, encrypt after described encryption key is read in master control and open hard disk, carry out the read-write of normal hard disc data and process, during read-write, use built-in encryption algorithm process hard disc data.
TCM(trusted cryptography module credible password module) be China's credible calculating standard hardware module, possess crypto-operation device and Guared memory, embedded national Password Management office canonical algorithm.TCM protects user key and data by key tree, and private key can not leak, and possesses and prevent cracking mechanism in chip, safe.
In addition, radio-frequency card becomes emerging safe access control mode recently as user's ID authentication device, radio-frequency card is realized authentication by induction mode by reader and antenna in short distance, in radio-frequency card, canned data can be read as user authentication information and is transferred to master control by reader, this mode is without change storer and Portable computer housing structure
Compared with prior art, the beneficial effect producing is the utility model:
This programme adopts hardware encipher, does not take cpu resource, does not need to install to drive, and hard disk is encrypted totally; TCM storage key is safer, and safe storage Offhost TCM environment cannot be deciphered, and radio-frequency card is convenient for carrying as identification apparatus, without memory authentication password, does not need to change portable computer BIOS and shell mechanism.
Accompanying drawing explanation
Accompanying drawing 1 is structured flowchart of the present utility model.
Embodiment
In order to make technical method of the present utility model, advantage clearer, under in conjunction with the accompanying drawings and embodiments the utility model is further elaborated.
A safe storage, comprises hard disk, embedded controller and encryption master control as shown in drawings, also comprises power module, radio-frequency card reader and antenna.Hard disk is connected with encryption master control by SATA interface, and embedded controller is connected with power module with encryption master control, radio-frequency card reader respectively, and radio-frequency card reader is connected with antenna.
Encrypting master control connection SATA interface is connected with hard disk end, a SATA interface of another connection is connected with host side, encrypt master control and can change SATA agreement, built-in encryption algorithm, accept encryption key, disk read-write data are carried out to encryption and decryption, and to hard disk, transmission is filtered in order, keeps safe storage and main-machine communication.The present embodiment also needs the built-in TCM chip-stored encryption key of main frame, user's embedded controller when first use by radio-frequency card transmitting subscriber identify, encrypt one section of random number be stored in TCM in as encryption key.Embedded controller is built-in with program and completes key management and authentication logic.
After above-mentioned encryption key initialization, user uses the workflow of safe storage to be, after main frame start powers up, to loading the hard disk stage, encrypt master control and intercept and capture the embedded controller traffic encryption keys to be read such as hard disk instruction, user is placed on hard disk areas by radio-frequency card, antenna induction is after radio-frequency card, radio-frequency card reader reads the user profile in radio-frequency card, embedded controller reads the user profile that radio-frequency card reader reads, encryption key using described user profile as secret key decryption TCM storage inside, embedded controller is transferred to encryption master control by encryption key, if encryption key is correct, encrypt master control and open the read-write processing that hard disk carries out normal hard disc data, during read-write, use built-in encryption algorithm process hard disc data.
Except the technical characterictic described in instructions, be those skilled in the art's known technology.
