Two kinds of security chip having a security interface are provided. One kind of the security chip comprises a processor module, a encrypt/decrypt module, a memory module, a power detecting module and a security I/O module, and all of the modules are connected with each other by a internal bus in the security chip; the other kind of the security chip comprises a processor module, a encrypt/decrypt module, a memory module, a power detecting module and a I/O interface module, all of the modules are connected with each other by the internal bus in the security chip, wherein, the security chip also comprises a security input module, a security output module and a south bridge interface module, and all of the modules are connected with each other by the internal bus in the security chip. With the security chip provided by the present invention, it is possible to encrypt/decrypt the I/O information of a information processing device, ensure the I/O information safety, thus prevent the information from listening, avoid revealing the information. |
