Abstract

The embodiment of the invention discloses an encryption method, an encryption device and an encryption performance analysis method and device. The encryption method comprises the steps of selecting target key data from key data of target information, wherein the key data is basis for confirmation of other data in the target information; carrying out random selection on all target key data to determine to-be-encrypted information in the target key data; encrypting the to-be-encrypted information in the target key data through adoption of an encryption algorithm, and obtaining encrypted data corresponding to the target key data; and correspondingly replacing the target key data in the target information by the encrypted data, thereby encrypting target information.

Description

technical field [0001] The present application relates to the technical field of information security, and in particular to an encryption method, an encryption device, and an encryption performance analysis method and device. Background technique [0002] In the field of encryption, people are used to encrypting all the protected data, which is undoubtedly a very safe method at the level of cryptanalysis. However, compared with traditional text information and static images, video not only has a large amount of data, but also meets the needs of real-time transmission, such as webcasting, video conferencing, etc. If all video data is encrypted, high-complexity encryption algorithms and A large amount of encrypted data will cause a huge overhead on the server. The throughput rate of AES-256 provided by the openSSL library mainly used for secure network data transmission is about 96Mbps-524Mbps. Therefore, in order to reduce server overhead, the same video content is generall...
