[0062]

[0063] Where D 1m represents the standard packet loss rate measurement value in the mth preset time period, D 2m represents the standard bit error rate measurement value in the mth preset time period, D0 represents the preset packet loss rate threshold, D1 represents the preset bit error rate threshold, β1 represents the preset fault first weight, β2 represents the preset fault second weight, and e represents a natural constant.

As the standard packet loss number d 1m and the standard error code number g 1m The increase of the standard total number of packages d m And the standard total code word number g m The transmission accuracy index gradually decreases, and the standard packet loss number d 1m and the standard error code number g 1m Negatively correlated with the transmission accuracy index, the standard total number of packets d m And the standard total code word number g m It is positively correlated with the transmission accuracy index, so it can be accurately analyzed by establishing a mathematical form.

The receiver uses the same algorithm and key as the encryption to decrypt. After the decryption is completed, the original plaintext information is obtained and output or processed later. The preset key generation algorithm is used to generate the key required in the encryption process. The key should be randomly generated to avoid being predicted or guessed; the accuracy of gateway state switching during gateway communication is improved.

[0071] Furthermore, the specific method for obtaining the encryption security index is as follows: encryption-related data is obtained through a third measuring device during an encryption time period, the encryption time period represents a preset time period in the process of encrypting the initial gateway data, the third measuring device includes a network performance analyzer and a timer, the encryption-related data includes a standard data volume, a standard processing time, a standard number of requests and a standard total processing time, the standard volume represents the data volume of the encrypted gateway data during the encryption time period, the standard processing time represents the time required for encrypting the encrypted gateway data during the encryption time period, the standard number of requests represents the total number of requests for encryption of the encrypted gateway data during the encryption time period, and the standard total processing time represents the total duration of requests for encryption of the encrypted gateway data during the encryption time period; based on A standard encryption speed measurement value is obtained based on the standard data volume and the standard processing time, and a standard throughput measurement value is obtained based on the standard number of requests and the standard total processing time. The standard encryption speed measurement value represents the measurement value of the encryption speed in the encryption time period, and the standard throughput measurement value represents the measurement value of the throughput in the encryption time period. A preset encryption speed threshold, a preset throughput threshold, a first encryption weight, and a second encryption weight are obtained from a preset database, and an encryption security index is obtained in combination with the standard encryption speed measurement value and the standard throughput measurement value. The first encryption weight is used to evaluate the degree of influence of the standard data volume and the standard processing time on the encryption security index, and the second encryption weight is used to evaluate the degree of influence of the standard number of requests and the standard total processing time on the encryption security index.

[0072] In this embodiment, the encryption security index is calculated using the following formula:

[0074] In the formula, represents the encryption security index in the nth encryption time period, n = 1, 2, ..., t, n represents the number of the encryption time period, t represents the total number of encryption time periods, B 1n represents the standard encryption speed measurement value in the nth encryption time period, B 2n represents the standard throughput measurement value in the nth encryption time period, B0 represents the preset encryption speed threshold, B1 represents the preset throughput threshold, θ1 represents the first encryption weight, θ2 represents the second encryption weight, and e represents a natural constant.

[0075] The preset encryption speed threshold is represented by the average value of the encryption speed data in the preset database, and the preset throughput threshold is represented by the average value of the throughput data in the preset database.

[0076] Specifically, the first encryption weight is obtained from a preset database; in a specific embodiment, a mapping set of standard data volume deviation values ​​and their corresponding weights is constructed based on the relationship between historical standard data volume deviation values ​​and encryption security indexes, and the real-time standard data volume deviation values ​​are input into the mapping set to obtain the corresponding first encryption weight.

[0078] Specifically, b 1n represents the standard data volume in the nth encryption time period, t 1n represents the standard processing time in the nth encryption period, b 2n represents the number of standard requests in the nth encryption period, t 2n represents the standard total processing time in the nth encryption time period. The algorithm in this embodiment combines the standard data volume b 1n , standard processing time t 1n , Standard request number b 2n and the standard total processing time t 2n , comprehensive analysis to obtain the encryption security index, the standard data volume b in this formula 1n , standard processing time t 1n , Standard request number b 2n and the standard total processing time t 2n There is a common regulatory association between 1n and the standard number of requests b2n The increase of standard processing time t 1n and the standard total processing time t 2n The encryption security index gradually increases, and the standard data volume b 1n and the standard number of requests b 2n Positively correlated with the encryption security index, the standard processing time t 1n and the standard total processing time t 2n It is negatively correlated with the encryption security index, so it is accurately analyzed by establishing a mathematical form.

[0081]

[0082] As can be seen from the table, with the standard data volume b 1n and the standard number of requests b 2n The standard processing time t 1n and the standard total processing time t 2n The encryption security index gradually increases as the value decreases, which means that even in the face of massive data input and frequent request processing, complex calculations and responses can be completed in a shorter time, which means that the security of the initial gateway data encryption process is gradually enhanced; the accuracy of gateway state switching during gateway communication is improved.
