Problems solved by technology

[0003] However, according to the current data security transmission mode, the security strength of the transmitted data cannot be adjusted, that is, the overall data must be encrypted using a unified encryption method, and the current resource availability on the network side or the terminal side is not considered. , using a unified security encryption mechanism for the entire data may result in a waste of processing resources on the terminal or network side

Embodiment 1

[0022] Such as figure 1 As shown, it is a flow chart of the specific implementation principle of the method for delivering the health index used to characterize the resource usage of the network side proposed by the embodiment of the present invention, and the specific implementation process is as follows:

[0023] Step 10, obtain each parameter value used to characterize the current resource usage of the network; wherein each parameter value obtained may include but not limited to at least one or more of the following parameter values: the average CPU usage rate of each server on the network side Value; the average value of the memory usage of each server on the network side; the average value of the CPU temperature of each server on the network side; the average value of the hard disk space usage of each server on the network side; .

[0024] Step 20, based on the parameter values ​​obtained above, determine the health index value used to characterize the current resource u...

Embodiment 2

[0033] Correspondingly, as figure 2 As shown, it is a flow chart of the implementation principle of the first method for securely transmitting data proposed in the embodiment of the present invention, and the specific implementation process is as follows:

[0034] Step 200, calculating summary information of the overall data to be transmitted, and encrypting the calculated summary information before transmitting. Of course, this step is an optional step, that is, you can choose not to calculate the summary information of the overall data to be transmitted, and perform encrypted transmission on the calculated summary information. Here, the summary information is calculated for the overall data to be transmitted, and the calculated The main purpose of encrypting and transmitting the summary information is to ensure the integrity of the overall data transmission.

[0035] Step 201, dividing the overall data to be transmitted into at least one data block;

[0036] Step 202, sel...

[0055] Such as image 3 As shown, it is a flow chart of the implementation principle of the second method for securely transmitting data proposed in the embodiment of the present invention, and the specific implementation process is as follows:

[0056] Step 300, calculate summary information of the overall data to be transmitted, and encrypt the calculated summary information before transmitting. This step is optional.

[0057] Step 301, divide the overall data to be transmitted into at least one data block, and perform out-of-order processing on each of the divided data blocks; the so-called out-of-order refers to disrupting the sequence of the divided sequential data blocks, so that The adjacent data blocks may not be continuous in content after being scrambled.

[0058] Step 302, selecting an unsent data block in sequence from the out-of-order data blocks;

[0059] Step 303, randomly generating a random number for the data block;

[0060] Step 304, determine the latest...

Abstract

The invention discloses a health index issue method for representing resource using conditions of the network side. The health index issue method includes obtaining all parameter values for representing current resource using conditions of the network side; determining a health index value for representing the current resource using conditions of the network side based on obtained parameter values; and issuing the determined health index value. The invention further discloses a secure transmission method for data. The secure transmission method for the data includes that the integral data to be transmitted is divided into at least one data block, and the data block obtained based on the division is subjected to the following operation which includes that a random number is randomly generated according to the data block; the newest health index value issued by the network side is determined and used for representing the resource using conditions of the network side; and whether the data block is subjected to encryption transmission is determined according to the relationship between the generated random number and the determined health index value. By means of the secure transmission method for the data, occupation of processing resources can be reduced on the basis that the integral data is transmitted securely.

Description

technical field [0001] The present invention relates to secure communication technology in the field of communication, in particular to a health index distribution method and device for characterizing resource usage on the network side, and a method and device for safely transmitting data. Background technique [0002] At present, when data transmission is carried out in the communication network system, the overall data transmitted is generally encrypted and integrity protected for security assurance processing, which not only adopts full-flow operation, but also adopts a symmetric cryptosystem to improve the encryption efficiency. Both parties of the data encrypt all the data to be transmitted based on the common key, and transmit the encrypted data through the network. Even if the data is intercepted during the transmission, it cannot be restored without the key. The real plaintext content, so as to realize the confidential and safe transmission of the transmitted data. ...
