A portable terminal with transparent data security protection for mobile applications

Abstract

The invention provides a portable transparent data safety protection terminal oriented to mobile applications. The terminal is mainly divided into a data encryption and decryption module part and a mobile equipment client end part. According to the data encryption and decryption module part, a TPM (trusted platform module) and a chip which supports international standard encryption algorithms are used for achieving high-speed hardware data encryption and decryption computation, and a file encryption and decryption service is provided for the outside through Bluetooth or a wireless network. Meanwhile, the data encryption and decryption module part is based on a trusted computing architecture, and the trusted authentication of a user, the terminal and mobile equipment is achieved. According to the mobile equipment client end part, the data encryption and decryption service provided by an encryption and decryption module is called based on the Bluetooth or the wireless network, meanwhile, a local remote file system service is achieved, a data file storage service is provided for the mobile applications, the stored data are encrypted in the way of calling the encryption and decryption service by the mobile equipment client end part, the taken-out data are decrypted by the mobile equipment client end part, and therefore transparent encryption and decryption oriented to the mobile applications is achieved.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a mobile application-oriented transparent data security protection portable terminal. Background technique [0002] With the substantial improvement in the performance of mobile devices such as mobile phones and PADs, mobile applications have also become a rapidly developing emerging computing model, and the scope of mobile applications is also showing a rapid expansion trend. Mobile applications include not only instant messaging, entertainment, etc., but also applications in mobile payment, mobile office, data storage, and remote data access, and most of these applications involve high-value and private data. Such data stored in mobile devices faces special security risks, such as: mobile terminals are easy to be lost, stolen, stolen, etc. Due to the limited computing resources and capabilities of mobile terminals, existing information security protection technolo...
