Abstract

The invention provides a data transmission system and a data transmission method. Data to be transmitted is subjected to definition of the security level; and the data in different security levels are encrypted in different forms. In the encryption, a chain-type encrypting process combined by one or more encrypting algorithms is used, so the security of the data is guaranteed, and the process of the encrypting algorithms is suitable for the data to be transmitted and processing devices.

Description

technical field [0001] The present invention relates to data transmission technology, in particular, to a data transmission system and method Background technique [0002] In existing software encryption systems, most applications use a fixed encryption algorithm (combination) to protect data security when using encryption and decryption functions. The advantage of doing this is obvious: the encryption module using a fixed encryption algorithm (combination) is simple in design, and after selecting a high-strength encryption algorithm, its data security performance is very good. However, such design flaws are also very obvious: regardless of the characteristics of the data, it is uniformly processed according to the same encryption and decryption method. For top-secret data, the encryption strength may not be enough. For public data, it is completely unnecessary. It may waste computing resources; at the same time, using the same encryption algorithm (and key set) for a long ...
