The data encryption control module is also connected with a data encryption and decryption module. Compared with the prior art, the encryption storage chip has the advantages of reasonable design, simple structure, convenient use and the like. Due to the adoption of the encryption storage chip, the device quantity of storage encryption equipment is reduced and the high-speed encryption and decryption requirements of storage data are satisfied. The encryption storage chip can be widely used for the encryption and decryption of SATA interface storage equipment, such as computer mobile storage devices, computer hard disks and the like.
Description
Technical field
The utility model relates to the data safe storing equipment technical field, a kind of specifically storage enciphered storage chip of Computer Data Security storage
Background technology
Protection to data content itself is the focus technology that present world security circle is paid close attention to, and is one of present safety technique Development Trend.Real safety should be done from ensureing data, but not defensive attack.As long as it is good that the data protection is done; Even if the hacker has stolen important data, also can't within the valid period, crack relevant documentation, information security technology is from initial defensive attack; Progressively turn to the protection to information itself, storage security is one of important development trend of present safety technique.
In recent years; Because mobile storage is lost or the stolen frequent generation of information leakage incident that causes; The security of significant data has become the problem of social extensive concern in the mobile storage, gently then reveals individual privacy, infringement commercial interest, and is heavy then concern national security.Storage security is since late nineteen nineties in last century; From network security, spin off gradually; Develop in the information security independently field; And domestic a large amount of research at present, exploitation and practical application all concentrate on network security and the security of system, and the research and technology exploitation of storage security is in blank.A lot of storage manufacturers so-called " storage security product " also only stop at elementary encryption, more do not have the gordian technique of oneself, and domestic research and development and production memory protection product remain difficulty technically.Therefore, safe storage system technology and product that research and development has independent intellectual property right, the information security infrastructure construction to China has the important strategic meaning.
Summary of the invention
The technical assignment of the utility model is the deficiency that solves prior art, and a kind of storage enciphered storage chip of high security storage of computer data is provided.
The technical scheme of the utility model realizes by following mode; This storage enciphered storage chip; Its structure comprises SATA protocol-analysis model, the data encrypting and deciphering control module that connects SATA host device interface and SATA slave unit interface, and described data encrypting and deciphering control module also is connected with the data encrypting and deciphering module, and above-mentioned SATA protocol-analysis model is meant the SATA protocol analyzer; The data encrypting and deciphering control module is meant the data encrypting and deciphering controller, wherein:
SATA slave unit interface connects the SATA main equipment;
The SATA host device interface connects the SATA slave unit.
The SATA protocol-analysis model is used to analyze the SATA host-host protocol, and whether analyze order needs encryption and decryption;
The data encrypting and deciphering control module is used for the flow direction of control data, and according to the result of SATA protocol-analysis model, control data is encrypted or deciphering;
The data encrypting and deciphering module is used for data are encrypted or deciphering.
Described SATA host device interface comprises computer motherboard; SATA slave unit interface comprises hard disk.
What described data encrypting and deciphering module adopted is the close algorithm of state.
The beneficial effect that the utility model is compared with prior art produced is:
Characteristics such as that a kind of storage enciphered storage chip of the utility model has is reasonable in design, be skillfully constructed can be used for the storage encryption and decryption of computer system.Reduce the number of devices of storage encryption equipment, satisfied demand, can be widely used in the encryption and decryption of SATA interface memory devices such as the interior hard disk of computing machine movable storage device and computing machine storage data in high speed encryption and decryption.

1, SATA slave unit interface, 2, the data encrypting and deciphering control module, 3, the SATA protocol-analysis model, 4, the data encrypting and deciphering module, 5, the SATA host device interface.
Embodiment
Below in conjunction with accompanying drawing the storage enciphered storage chip of the utility model is done following the detailed description.
Shown in accompanying drawing 1; This storage enciphered storage chip; Its structure comprises SATA protocol-analysis model 3, the data encrypting and deciphering control module that connects SATA host device interface 5 and SATA slave unit interface 1; Described data encrypting and deciphering control module also is connected with data encrypting and deciphering module 4, and wherein: SATA slave unit interface 1 connects the SATA main equipment, and this SATA main equipment comprises computer motherboard etc.; SATA host device interface 5 connects the SATA slave unit, and this SATA slave unit comprises the hard disk lamp; SATA protocol-analysis model 3 is used to analyze the SATA host-host protocol, and is to the order that does not need encryption and decryption that data link is direct-connected, to needing the order notification data encryption and decryption controller of encryption and decryption; Data encrypting and deciphering control module 2 is used for the flow direction of control data, and according to the result of SATA protocol-analysis model 3, control data is encrypted or deciphering; Data encrypting and deciphering module 4 is used for data are encrypted or deciphering, its encryption or to decipher used algorithm be the close algorithm of state.
The course of work of the storage enciphered storage chip of the utility model is following; SATA slave unit interface 1 receives that data are sent to SATA protocol analyzer module later on; Command interpretation according to the data of being received; Confirm that these data are directly to transmit or revise the back to transmit, if to the read write command of memory device then notification data encryption and decryption control module 2 carry out the encryption or the deciphering of data:
If encrypt; Data encrypting and deciphering control module 2 will receive from the data of SATA slave unit interface 1 and send into data encrypting and deciphering module 4; And notify it to carry out cryptographic operation; Data encrypted turns back to data encrypting and deciphering control module 2, and data encrypting and deciphering control module 2 is delivered to SATA host device interface 5 with data, gets into the memory device of SATA interface;
If deciphering; Data encrypting and deciphering control module 2 will receive from the data of SATA host device interface 5 and send into data encrypting and deciphering module 4; And notify it to carry out decryption oprerations; Data encrypted turns back to data encrypting and deciphering control module 2, and data encrypting and deciphering control module 2 is delivered to SATA slave unit interface 1 with data, transmits to get into computer system.
