Problems solved by technology

[0015] In addition, most of the encryption algorithms for streaming media currently on the market are related to the format of the streaming media (generally subpackaged according to the streaming media type). The purpose of this is to reduce the complexity of the algorithm while obtaining strong security. However, the versatility of the algorithm is sacrificed, and different algorithms need to be adopted for different types of streaming media types, such as: streaming media encryption and decryption methods, encryption and decryption devices (patent application publication number: CN104580236A)

Embodiment Construction

[0039] Such as Figure 10 As shown, this streaming media information security guarantee method is a symmetric encryption algorithm, and the encryption includes the following steps:

[0040] (1) Read in the password, and analyze the initial sign, the operation control word and the password, if the analysis is wrong, then exit and give an error message; if the analysis is correct, then perform step (2);

[0041] (2) De-align the operation control word and password according to the analytical value of the start flag;

[0042] (3) Carry out group calculation to the cipher controlled by each control operation word, and form the final cipher block;

[0043] (4) according to the length of each cipher block, the plaintext to be encrypted is grouped to form a group set;

[0044] (5) According to the encryption algorithm specified in the operation rule field of the operation control word, the corresponding password is used to encrypt and calculate the plaintext to be encrypted, and fi...

Abstract

The invention discloses a streaming media information safety guarantee method. The method is a symmetrical encryption algorithm and comprises the following steps during encryption: (1) reading in passwords, and analyzing a start flag, an operation control word and the passwords, if a mistake is made during analyzing, quitting and giving out an error-reporting message, and if the analyzing is correct, executing a step (2); (2) aligning the operation control word and the passwords according to an analytic value of the start flag; (3) carrying out marshalling calculation on the password controlled by each control operation word, and forming final password groups; (4) according to the length of each password group, grouping to-be-encrypted plaintext, and forming a grouping set; and (5) according to encryption operation rules designated by an operation rule field of the operation control word, carrying out encryption calculation on the to-be-encrypted plaintext with the corresponding password, and finally generating ciphertext. The invention also discloses a streaming media information safety guarantee system.

Description

technical field [0001] The invention relates to the technical field of information security in the fields of video monitoring, video conferencing, etc., and in particular to a streaming media information security guarantee method and a streaming media information security guarantee system. Background technique [0002] As technologies such as video surveillance and video conferencing are more and more applied to our daily work and life, information security in the transmission, storage, and playback of streaming media is becoming more and more important. How to efficiently and intensively guarantee the information security of streaming media information in each link has become a focus of attention and research. [0003] At present, streaming media is generally encrypted based on conventional encryption technology. These methods can achieve high-intensity encryption of information, but generally have low encryption efficiency, complex algorithms, low real-time performance, an...
