Abstract

The invention discloses a high-efficiency data compression and encryption system. The system comprises a data input control module, a data caching module, a compression and encryption module and a data output control module, wherein the data input control module is used for controlling received data and control signals to be stored in the data caching module; the compression and encryption module comprises a compression mode control module, a general Gzip compression module, a special Gzip compression module, an encryption module and a special Gzip compression and encryption module. The invention discloses a method organically combined with lossless compression and encryption, and an ordinary Gzip compression algorithm is pointedly improved to obtain a specialized Gzip compression algorithm; meanwhile, the compression mode control module can be selected between loose and tight coupling modes subjected to general Gzip compression, special G zip compression, compression and encryption according to control signals, thereby effectively improving data compression rate and data transmission security.

Description

technical field [0001] The invention belongs to the field of computer information security, and in particular relates to an efficient data compression and encryption system. Background technique [0002] With the development of Internet technology and cloud computing technology, more and more data needs to be stored and transmitted, and the storage and transmission costs of these massive data are very high. At the same time, they also face the risk of data theft during transmission. In order to alleviate this The problem is that the data is usually compressed and encrypted before the data is stored and transmitted. The compressed data can not only greatly increase the effective capacity of the disk, reduce the cost of the Internet data center, but also ensure the security of the compressed data. [0003] According to current knowledge of cryptanalysis, the ECC encryption algorithm is recognized as the one that provides the highest encryption strength per bit in the currently...
