Embodiment Construction

[0015] The above and other features and advantages of the present invention will be described in more detail below with reference to the accompanying drawings.

[0016] figure 1 is a block diagram of the internal structure of the key generating device according to the present invention.

[0017] Such as figure 1 As shown, the key generation device 100 includes a memory unit 101 , an input and output unit 102 , a random number generation unit 103 , an algorithm unit 104 and a main control unit 105 .

[0018] The memory unit 101 is connected with the main control unit 105 and is used for storing program codes and providing memory required for system operation. The memory component 101 may include: a synchronous dynamic random access memory, which is used to provide the memory required for the operation of the key generation device; and a flash memory (FLASH memory), which is used to store program codes.

[0019] The input and output unit 102 is connected with the main control...

Abstract

The invention provides a device and a method for generating a cipher code based on digital contents and a data encrypting method. The cipher code generating device comprises a memory component, a random number generating component, an arithmetic component, an input and output component and a main control component which is respectively connected with the memory component, the random number generating component, the arithmetic component and the input and output component so as to control the operation of the components. Randomness and safety of cipher code generating can be met and the data can be effectively encrypted by using the cipher code generating device and the cipher code generating method based on the cipher code generating device and the data encrypting method of the invention, thus guaranteeing the security of the digital contents and maintaining the security and reliability of the data communication.

Description

technical field [0001] The present invention relates to a key generation device and a key generation method, more specifically, to a digital content-based key generation device and key generation method, and using the key generation device and key generation method The method by which data is encrypted. Background technique [0002] At present, with the development of information technology, the sales of digital goods such as e-books, music images, movies and TV have been strongly promoted. The digital content contained in these digital goods includes multimedia content and text content, etc. In order to prevent piracy, various companies are developing corresponding technologies to encrypt data more effectively. [0003] In addition, during data communication, effective encryption of data is also an important means to protect data security. [0004] Whether in the digital copyright protection system established to prevent piracy or in the encryption process of data commun...
