Embodiment Construction
[0043] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, wherein the schematic embodiments and descriptions are only used to explain the present invention, but not as improper limitations to the present invention.
[0044] In a trusted computing environment, mobile devices can be connected to hosts, storage systems, etc. in the trusted computing environment through wireless interconnection, such as WIFI, GPRS, etc., so as to further access the data stored in the trusted computing environment. In order to prevent unauthorized mobile devices from reading data, it is necessary to verify the identity of the mobile device. see figure 1 The flow chart of a preferred embodiment of the technical solution proposed by the present invention, in S01, the mobile phone device sends an access request for reading data to the trusted computing environment, and this request can read the host computer of the trusted co...

The invention discloses a method for mobile phone equipment to read data in a trusted computing environment. The trusted computing environment comprises a trustworthiness verification device and an encryption device. The method is characterized by comprising the following steps that the mobile phone equipment sends an access request for read data to the trusted computing environment; the trustworthiness verification device verifies the identity of the mobile phone equipment; if it is verified that the mobile phone equipment is trusted equipment, the read data access request of the mobile phoneequipment is directly executed; and otherwise, the encryption device is controlled to conduct encryption processing on the requested read data, the requested read data is replaced with ciphertext obtained after encryption, and then the read data access request of the mobile phone equipment is executed. According to the method, the flexibility that the mobile phone equipment uses the trusted computing environment can be effectively improved while the security is not reduced.
Description
【Technical field】 [0001] The invention relates to the technical field of computer security, in particular to a method for a mobile phone device to read data in a trusted computing environment. 【Background technique】 [0002] With the rapid development of computer information and network storage technology, mobile devices have become an important storage device in people's daily life. The file is transferred by storing the file in the storage area of the mobile device, but at the same time it also causes data security problems, because the mobile device usually does not have encryption and identity authentication functions. In the prior art, trusted computing can be used to ensure the security of hardware devices, thereby extending to the security of data. The concept of trusted computing is defined in the ISO / IEC 15408 standard as follows: a trusted The behavior of a component, operation, or process is predictable under arbitrary operating conditions and is highly resista...
