Abstract

The invention discloses an encryption transmission method and device and decryption playing method and device of a multimedia file, and relates to the field of information security. The main purpose is to solve the problems that the encryption is relatively complex and the decryption playing speed of the multimedia file is low. The technical scheme provided by the invention comprises following steps of firstly, obtaining the encryption mode of the multimedia file corresponding to a multimedia file identifier, the length information of an encryption secret key and the encryption secret key; through taking the length of the encryption secret key as a unit, carrying out preset logic operations to the data in the multimedia file and the encryption secret key, thus obtaining an encrypted multimedia file; through taking the encryption mode and the length information of the encryption secret key as an encryption file header, according to a front to back sequence of the encryption file header, the encryption secret key and the encrypted multimedia file, generating an encrypted data file; and finally, sending the encrypted data file to a client. The methods and the devices are mainly used for carrying out encryption transmission and decryption playing to the multimedia file.

Description

technical field [0001] The invention relates to the field of information security, in particular to a multimedia file encryption transmission, decryption playback method and device. Background technique [0002] Nowadays, the world has entered the information age, and the computer network has developed rapidly, which is related to all aspects of social life. However, while enjoying the convenience brought by the Internet, we also face many problems. One of the most prominent problems is the problem of network information transmission security. In order to solve the problem of network information transmission security, people often use file encryption to protect the process of network information transmission. Data encryption refers to the conversion of plaintext into ciphertext through encryption algorithms and encryption keys to realize information concealment, thereby protecting information security. [0003] In order to meet the requirement of online broadcast and decry...
