Detailed Description
The present application is described in further detail below with reference to the attached drawings.
The embodiment of the application discloses a security management and control method for a public service vehicle, which can be realized through a server optionally. Referring to fig. 1, the method for managing and controlling the safety of the public service vehicle includes:
receiving and acquiring vehicle information of each target; receiving and acquiring driving license information, judging whether the driving license information is a safety license, and if the driving license information is the safety license, performing data interaction with the user terminal by adopting a safety channel; and if not, performing data interaction with the user terminal by adopting an http protocol.
Wherein, the vehicle information is sent to a server for realizing the method by a vehicle-mounted unit (such as a vehicle-mounted host); the vehicle information comprises vehicle identification information and position information, and the vehicle identification information is manually input into the vehicle-mounted unit by a worker for identifying each vehicle; the location information may be: the vehicle-mounted unit is processed according to the positioning information received from the satellite positioning system, such as: the vehicle-mounted GPS positioning unit receives positioning signals sent by a GPS satellite and a Beidou satellite and processes the positioning signals to obtain longitude and latitude information; the method also comprises the following steps: the on-board unit acquires position information from a navigation system (a high-grade map, a Baidu map, etc.) through a transceiver.
The driving permission information comprises a vehicle identification code used for matching with a target vehicle, user identity information and a permission identification code; wherein, the permission identification codes are divided into a plurality of classes, one class is a first class identification code, one class is a second class identification code, and the other class is a special class identification code; the security permission is as follows: the driving license information includes a secondary identification code or a special identification code.
When the system is used, a user accesses the server through a user terminal (such as hardware equipment corresponding to a Web browser) to acquire vehicle information and know the position of each target vehicle; correspondingly, the user needs to input user identity information including an account and a password when accessing the server; and when the user identity information is matched with the user identity information which is filed in the preset authority library, access is allowed, so that preliminary information safety control is realized.
According to the above, in view of information security, the method further classifies the user terminal access modes into two types according to whether the driving license information is a security license;
when the driving license information does not contain a secondary identification code or a special identification code, namely non-safety license, the user terminal adopts an http protocol to perform data interaction with the server; the http protocol is a hypertext transfer protocol, which transmits contents in a plaintext manner without providing data encryption, and relatively, has poor information security, and is generally used in daily use processes of a business car, for example: street/park visits, etc.
When the driving license information contains a secondary identification code or a special identification code, the user terminal adopts a safety channel to perform data interaction with the server, and the link comprises the following steps:
establishing data interaction with a preset http protocol page through an https protocol;
the https protocol page acquires user identity information and access time; and receiving and acquiring user identity information and access time from a preset https protocol page through an http protocol, verifying whether the user identity information conforms to the user identity information, if so, accumulating the access time and a preset T1 permission duration to obtain a safe time length, and transmitting the target vehicle information to the preset https protocol page within the safe time length.
Firstly, HTTPs is a network protocol which is constructed by an SSL + HTTP protocol and can perform encryption transmission and identity authentication, and is a plaintext transmission of an HTTP protocol which is transmitted in an abnormal state, so that the HTTPs is relatively difficult to directly capture packets to acquire information and is safer;
secondly, in the second data interaction mode, the http protocol page is selected to be skipped instead of pure http protocol communication, that is, the user can log in and access through http, and then skip the http protocol page to access, so that the fluency of data interaction is improved;
thirdly, the permission time of T1 (such as 2 minutes) is set in the second data interaction mode, the safety time is respectively determined according to the access time of each time, and the target vehicle information is sent to the https protocol page only in the time, so that the information safety is further improved.
In order to further improve information security, the method also selects to invoke the WCF service to encrypt the transmission information, and the invoking the WCF service to encrypt the transmission information comprises:
providing the WCF service class according to the preset;
namely, [ ServiceContract ]
[AspNetCompatibilityRequirements(RequirementsMode=AspNetCompatibilityRequirementsMode.Allowed)]
public class WCFService”
Determining user identity information required to be decrypted;
processing user identity information according to a preset decryption/encryption mode and re-encrypting the generated information, converting the encrypted stream into a byte array, then converting the byte array into a processed character string by using Base64 encoding, and transmitting the processed character string serving as the user identity information to an http protocol page connected with the user identity information through an http protocol within a safe time.
The decryption/encryption mode includes that a key derivation function based on a password is realized by using a pseudo-random number generator based on HMACSHA1 in the process of re-encryption, and the user identity information and corresponding information are updated each time through the password and a salt derived key.
Simple example of decryption/encryption:
// decrypt data
public string Decrypt(string input)
{
// salt value (consistent with the value set upon encryption)
string saltValue = "saltValue";
V/cipher value (consistent with the value set during encryption)
string pwdValue = "pwdValue";
byte[]encryptBytes = Convert.FromBase64String(input);
byte[] salt = Encoding.UTF8.GetBytes(saltValue);
AesManaged aes = new AesManaged();
Rfc2898DeriveBytes rfc = new Rfc2898DeriveBytes(pwdValue, salt);
aes.BlockSize = aes.LegalBlockSizes[0].MaxSize;
aes.KeySize = aes.LegalKeySizes[0].MaxSize;
aes.Key = rfc.GetBytes(aes.KeySize / 8);
aes.IV = rfc.GetBytes(aes.BlockSize / 8);
Subsequently, a symmetric decryptor object is created by using the current Key attribute and the initialization vector IV to obtain decrypted output, the decrypted target stream is connected with decryption conversion, and a byte sequence is written into the current Cryptostream (the decryption process is completed).
}
// encrypting data
private string Encrypt(string input)
{
V/salt number
string saltValue = "saltValue";
// cipher value
string pwdValue = "pwdValue";
byte[] data = UTF8Encoding.UTF8.GetBytes(input);
byte[] salt = UTF8Encoding.UTF8.GetBytes(saltValue);
Management class of// AesManaged-Advanced Encryption Standard (AES) symmetric Algorithm
AesManaged aes = new AesManaged();
Subsequently, a Key derivation function based on a password is realized by using a pseudo-random number generator based on HMACSHA1, a symmetric encryptor object is created by using the current Key attribute and the initialization vector IV through the password and the salt derivation Key, an encrypted output is obtained, the encrypted output is connected with encryption conversion, and finally the encrypted output is converted into a processed character string by using Base64 encoding.
}
The reason why the license identifier representing the security license is divided into the secondary identifier or the special identifier is that in consideration of the special driving requirements of the public service vehicle, the corresponding application is further configured as follows:
when the driving license is a safety license, judging whether the driving license information contains a special-level identification code, if so, marking the corresponding vehicle as a key vehicle, and replacing the vehicle information of the key vehicle with the vehicle information of another non-key vehicle; the replacement rule can be directly realized by the current random roll call (number drawing) program, and the names in the library are all current non-key vehicles; therefore, any non-key vehicle is replaced by the key vehicle information, so that the aim of shielding the key vehicle is fulfilled, and the information safety is effectively improved.
In order to improve the using effect of the method, the method further comprises the following steps:
