Problems solved by technology

[0005] The disadvantages are: the key data can be obtained by monitoring the data of the smart card interface, which is easy to be cracked physically, and it is difficult to guarantee the security of decryption and playback; since it is necessary to reserve a corresponding card slot for the smart card on the smart terminal, it greatly increases the number of smart terminals. area, resulting in unnecessary waste and reducing the integration of smart terminals

Embodiment 1

[0027] This embodiment provides a resource playing method for an intelligent terminal. The method of this embodiment may be executed by a resource playing system implemented by hardware and / or software for an intelligent terminal, and the implementation system is typically configured in an intelligent terminal capable of providing resource playing services.

[0028] For the sake of clarity, the smart terminal is first introduced.

[0029] see Figure 2a , is a schematic structural diagram of a smart terminal provided in Embodiment 1 of the present invention. The intelligent terminal includes: a safe shared memory, a network card, a monitor module, a decoder, a display module, an ordinary processor and a safety processor.

[0030] Wherein, the network card is connected with the common processor, and the monitor module, the decoder and the display module are respectively connected with the safety processor through a safety bus, and the safety bus protocol based on the safety b...

Embodiment 2

[0055] This embodiment provides a resource playing system for a smart terminal, and the resource playing system is typically configured in the smart terminal provided in the above embodiment. The structural diagram of the resource playback system configured in the smart terminal is as follows Figure 3a shown.

[0056] The system includes: a common operating system module, a resource acquisition module, a safe operating system module, a decryption module and a playback module.

[0057] Among them, the resource acquisition module runs on the common operating system module and is used to pass through the network card (such as Figure 3a As shown, the network card belongs to the hardware layer) obtains the resources to be played, and writes them into the secure shared memory (such as Figure 3a As shown, the secure shared memory belongs to the hardware layer), and the resource to be played is an encrypted resource; as Figure 3a As shown, the common operating system module and...

Abstract

The invention provides a resource play method and system for an intelligent terminal. The method comprises that a common processor drives a network card to obtain resource to be played, and writes the resource to be played in a safe shared memory, and the resource to be played is an encrypted resource; a monitor module switches the access authority of a safe processor to the safe shared memory; and the safe processor reads to resource to be played from the safe shared memory, a decoder is driven to decipher the resource to be played according to a preset secrete key and on the basis of a preset deciphering algorithm, resource that can be played is obtained, and a display module is driven to play the obtained resource. Thus, the secret key which needs to be deciphered tends not to monitor or crack, and the deciphering and playing safety of the resource to be played is ensured.

Description

technical field [0001] The embodiments of the present invention relate to the field of information technology, and in particular, to a resource playing method and system for smart terminals. Background technique [0002] The software industry is developing rapidly, and the market share of software products continues to increase. Correspondingly, many products have been cracked repeatedly and R&D companies have been hit hard. How to ensure product security and increase the difficulty of cracking is an unavoidable topic in the software industry. [0003] The Conditional Access System (CAS) currently used in the digital TV industry adopts the "card scheme", that is, the scheme of inserting a smart card into the smart terminal of the user terminal. The traditional smart card is independent of the smart terminal. Insert the smart card into the card slot of the smart terminal, and then perform data interaction through the smart card interface. [0004] The resource playback proc...
