Embodiment Construction

[0039] A method for encrypted transmission of Internet video data, comprising the following steps

[0040] Step 1: Set the video streaming capacity

[0041] According to the actual situation of network communication, set the minimum capacity of the network to transmit the video stream per unit time. The capacity is k. According to the actual situation of the network, the unit of k can be kilobytes, megabytes, Gbytes or other units, but k is a certain number.

[0042] Step 2: Encrypt

[0043] Step 2.1: Generate random numbers

[0044] Generate a random number with a minimum of 1 and a maximum of k, and the random number is a decimal integer, which is denoted as a 十 .

[0045] For example, in step 1, k is 14 megabytes, then the generated random number a 十 It can be any one of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, and 13.

[0046] Step 2.2: Hexadecimal Conversion

[0047] Random number a generated in step 2 十 converted to a binary number, which is denoted as a 二 . a 二...

Abstract

The invention belongs to an Internet data transmission method, and particularly relates to an Internet video data encryption transmission method. The method comprises the following steps: 1, setting avideo stream transmission capacity; 2, encryption: performing primary encryption on the video; 3, re-encryption: performing secondary encryption on the video; 4, t data packaging: packaging the datasubjected to secondary encryption; 5, transmission and decryption: transmitting the data in the step 4, and decrypting the data at a target node. The method has the remarkable effects that (1) the video is segmented and recombined, so that the aim of keeping the transmission process secret is fulfilled; if anyone does not know the video encryption method, the video cannot be played normally even if the video is obtained; (2) through two times of encryption, enough security of the video is ensured; and (3) the secret keys encrypted twice are transmitted separately, so that the video cannot be unlocked even if part of the video is obtained, and the security of the video is ensured to the greatest extent.

Description

technical field [0001] The invention belongs to an internet data transmission method, in particular to an internet video data encryption transmission method. Background technique [0002] As the Internet becomes more and more developed, Internet video is also used more and more widely. Divided from the confidentiality of Internet video, Internet video can be divided into wide-spread type and limited-dissemination type. Internet video of the limited transmission type means that, except for certain groups of people, no one is expected to see the content of the Internet video. [0003] The existing Internet video security methods are almost all member-based, that is, to achieve video security by cutting off the user's access to Internet video. The disadvantage of this method is that once the only barrier is breached, the video will be presented to the attacker without reservation. Therefore, there is an urgent need for a method that can keep the video confidential during tra...
