Device and method for realizing data transmission encryption through sata interface

Abstract

The invention provides a technical scheme of a device for data transmission encryption. The device comprises a microprocessor and an interface circuit which is connected with a host device, wherein the interface circuit is connected with a protocol analysis module, a first input caching module and a first output caching module are arranged for the protocol analysis module and a paper piece of the microprocessor, the microprocessor is also connected with a FLASH memory module and an encryption and decryption module, a second input caching module and a second output caching module are arranged for the protocol analysis module and the paper piece of the encryption and decryption module, and the microprocessor is connected with the encryption and decryption module. The device of the scheme is additionally arranged on a transmission medium, the data can be encrypted during the transmission process without additional memory equipment; and moreover, the encryption speed of the scheme is high, the transmission speed of the data cannot be influenced, the data which reaches a local end is a ciphertext, and the transmission data can only be read out through the decryption of the device of the scheme, so that the data safety during the whole transmission process is ensured.

Description

technical field [0001] The invention relates to a device and method for realizing data transmission encryption through a sata interface. Background technique [0002] In the prior art, the well-known technology is that the protection of content in the process of remote video data transmission, VPN, and electronic document transmission is the focus of current security field. When data is transmitted through network and other transmission media, it is extremely vulnerable to Hacker attacks, but if the transmitted data is properly protected, even if a hacker steals the data, it is difficult to crack it within the valid period of the data. [0003] At present, one of the more common secure transmission methods is to encrypt data before transmission. This method needs to be encrypted before data transmission, which has low work efficiency and requires additional storage hardware devices; the other is that the transmitted data is encrypted by the underlying protocol. This method ...

Problems solved by technology

[0003] At present, one of the more common secure transmission methods is to encrypt data before transmission. This method needs to be encrypted before data transmission, which has low work efficiency and requires additional storage hardware devices; the other is that the transmitted data is encrypted by the underlying protocol. This method does not require additional storage devices to obtain security encryption guarantees, but it can only achieve two-party security authentication, cannot support multi-party identity authentication, and can only guarantee the security of data during transmission. There are no regulations on safety, which is the deficiency of existing technology
