In the embodiment of the present application, the verification method for parking access is applied to a parking lot management system based on a block chain, please refer to fig. 3, where each parking service provider flag has one or more parking lot areas, each parking lot area can be regarded as a block, and each block is connected to form a parking lot block chain. In the parking lot management system, in the embodiment of the application, a node server is configured for each provider, and a provider client can upload respective parking service business logic protocols in a blockchain to complete uplink, so that data is permanently stored in the blockchain. The parking user can log in and access a certain node server through the parking user terminal, and in order to ensure the safety of user data, the parking user terminal can access the node server only after passing the verification. Specifically, the parking user terminal sends a parking access request to a node server corresponding to the parking lot, and after sending the parking access request to the node server, the parking user terminal receives first prompt information returned by the node server, where the first prompt information is used to prompt the parking user to input a private key. After the parking user terminal determines the input parameters input by the parking user on the interactive interface of the terminal, the parking user terminal can perform encryption operation on the input parameters to obtain first encryption parameters, and sends the first encryption parameters to the node server.
102, the parking user terminal encrypts a private key and an input parameter corresponding to the parking user terminal according to a verification default value returned by the node server, and sends a second encrypted parameter obtained by encryption to the node server, so that the node server decrypts the first encrypted parameter and the second encrypted parameter respectively to obtain a first decryption result and a second decryption result, and obtains a verification result based on the first decryption result and the second decryption result.
After the parking user terminal sends the first encryption parameter to the node server, the parking user terminal receives a verification default value returned by the node server, and in order to prevent the private key of the parking user terminal from being leaked, the parking user terminal conducts encryption operation on the private key and the input parameter corresponding to the parking user terminal through the verification default value to obtain a second encryption parameter, and sends the second encryption parameter to the node server, so that the node server conducts decryption on the first encryption parameter and the second encryption parameter respectively to obtain a first decryption result and a second decryption result, and obtains a verification result based on the first decryption result and the second decryption result, wherein the first encryption parameter is decrypted through a public key corresponding to the parking user terminal.
And 103, when the verification result is successful, the parking user terminal accesses the node server to acquire parking information.
And when the parking user terminal receives the verification result returned by the node server as successful verification, the node server can be accessed to acquire parking information to finish parking. It can be understood that after entering a certain node server, the parking user terminal can also switch to access other node servers to acquire parking information of other parking lots to complete parking arrangement.
In the embodiment of the application, when the parking user terminal sends the parking access request, the legalization verification of the user identity is carried out according to the parameters sent by the parking user terminal through the node server corresponding to the parking lot, and only when the verification is successful, the parking user terminal can access the node server to obtain the parking information to complete parking, so that the safety of the user information is ensured; moreover, the parking user terminal completes the identity verification on the premise of not revealing private key information, the private key cannot be revealed even if the parking user terminal is attacked in the identity verification process, the safety of user information is further ensured, and the technical problem that any access user can check parking user data and the safety is low because the access user does not perform identity verification in the conventional parking management system is solved.
The above is a first embodiment of the verification method for parking access provided by the present application, and the following is a second embodiment of the verification method for parking access provided by the present application.
For easy understanding, please refer to fig. 2, an embodiment two of the verification method for parking access provided by the present application includes:
The parking user terminal needs to perform encrypted registration before accessing each node server, and after sending a registration request to the node server, the parking user terminal receives second prompt information returned by the node server, wherein the second prompt information is used for prompting a user to determine two parameters, namely a first prime number and a second prime number, and the first prime number and the second prime number are two prime numbers with different sizes. For example, the second prompt message may be "please select two different prime numbers between (1, N"), and the parking user may randomly select two different prime numbers according to the second prompt message displayed on the interactive interface of the parking user terminal, where a specific value of N may be set according to an actual situation, and is not limited herein, and the values of the first prime number and the second prime number are preferably larger values.
The parking user terminal determines a private key s from the first prime number a and the second prime number b, and after the parking user terminal selects the first prime number a or the second prime number b as the private key s, the product c of the private key s and the first prime number a and the second prime number b is subjected to remainder to obtain a public key g corresponding to the private key s, namely g is s% c, and% is a remainder operation symbol; this private key s is known only to the parking user terminal. And the parking user terminal sends the parking user identification (mobile phone number, identity ID, registration number and the like), the public key g and the product c corresponding to the parking user terminal to the node server for storage.
In the verification process, after the parking user terminal sends a parking access request to the node server corresponding to the parking lot, first prompt information returned by the node server is received and used for prompting a user to input a private key, and the first prompt information can be' please be in (1, c-1)]To select a value ". The parking user terminal selects an input parameter m according to the first prompt message, and the registered user terminal determines that the input parameter m is one of a first prime number a and a second prime number b(when the private key is the first prime number, the input parameter m is the second prime number; when the private key is the second prime number, the input parameter m is the first prime number, so that the verification can be passed). And the parking user terminal carries out encryption operation on the input parameter m to obtain a first encryption parameter n and returns the first encryption parameter n to the node server. Specifically, the parking user terminal obtains a first encryption parameter n by taking the square of the input parameter m and the product c, that is, n is m2％c。
And step 204, the parking user terminal encrypts a private key and an input parameter corresponding to the parking user terminal according to a verification default value returned by the node server, and sends a second encrypted parameter obtained by encryption to the node server, so that the node server decrypts the first encrypted parameter and the second encrypted parameter respectively to obtain a first decryption result and a second decryption result, and obtains a verification result based on the first decryption result and the second decryption result.
After the parking user terminal sends the first encryption parameter n to the node server, the parking user terminal receives a verification default value P returned by the node server, and then calculates the product of the P power of a private key corresponding to the parking user terminal and an input parameter m according to the verification default value P returned by the node server to obtain a second encryption parameter k, namely k is m.spAnd sending the second encryption parameter k to the node server. And the first encryption parameter is decrypted through a public key corresponding to the parking user terminal.
Further, the values of the verification default value P include 0 and 1, which correspond to two different verification modes. The 0 mode (P ═ 0) is a self-test process, and also corresponds to a confusion mode; mode 1 (P ═ 1) is the decryption process. The parking user terminal passes through the two verification modes, and the verification can be successful only if the first decryption result and the second decryption result in the two modes are equal, but the parking user terminal does not know what mode the parking user terminal does.
Further, the node server decrypts the first encryption parameter and the second encryption parameter respectively to obtain a first decryption result and a second decryption result, and obtains a verification result based on the first decryption result and the second decryption result, which specifically includes: node server communicationDetermining a public key corresponding to the parking user terminal by the parking user identifier corresponding to the past parking user terminal, and obtaining a first decryption result of (nxg) by taking the residue of a value obtained by multiplying the power P of the public key by the first encryption parameter n and a product cp) % c, wherein the parking access request sent by the parking user terminal carries a parking user identifier corresponding to the parking user terminal; the node server takes the square of the second encryption parameter k and the product c to obtain a second decryption result k2％c。
And step 205, when the verification result is that the verification is successful, the parking user terminal accesses the node server to acquire the parking information.
When the first decryption result is equal to the second decryption result, the verification result is successful, that is, the parking user terminal knows the private key value, and the parking user terminal can access the node server to obtain parking information; and when the first decryption result is not equal to the second decryption result, the verification result is verification failure, and the parking user terminal cannot access the node server to acquire corresponding information. The interactive verification process has no backup record and adopts a traceless communication principle.
Further, when the parking user terminal selects the first prime number as the private key, and the input parameter when the parking user terminal accesses the node server is the second prime number, the verification is successful; or, when the parking user terminal selects the second prime number as the private key, the input parameter when the parking user terminal accesses the node server is the first prime number, the verification is successful, otherwise, the verification fails.
For example, the encryption process:
correspondingly, the parking user terminal calculates a product c of the first prime number and the second prime number as 17, and when the private key s is determined to be the first prime number, that is, s as 17, the public key g as s% c as 17.
And (3) decryption process:
if the input parameter m selected by the parking user terminal is 3, the first encryption parameter n is m2％c＝9；
When P is 0, secondEncryption parameter k is ms0The node server decrypts the first encryption parameter to obtain a first decryption result of (n × g) ═ 30) 9, the second decryption result obtained by decrypting the second encryption parameter is k2% c is 9, the first decryption result and the second encryption result are equal;
when P is 1, the second encryption parameter k is ms1The first decryption result is (nxg) 171) 170, the second decryption result is k2And% c is 17, the first decryption result and the second encryption result are not equal, and the verification fails.
If the input parameter m selected by the parking user terminal is 19 (the second prime number), the first encryption parameter n is m2％c＝38；
When P is 0, the second encryption parameter k is ms0When the node server decrypts the first encryption parameter, the first decryption result obtained is (n × g)0) 38, the second decryption result obtained by decrypting the second encryption parameter is k238, the first decryption result and the second encryption result are equal;
when P is 1, the second encryption parameter k is ms119 × 17, the first decryption result is (nxg)1) % c is 0, and the second decryption result is k2And when the% c is 0, the first decryption result is equal to the second encryption result, the verification is successful, and the identity of the parking user terminal is proved to be legal.
The above is an embodiment two of the verification method for parking access provided by the present application, and the following is an embodiment three of the verification method for parking access provided by the present application.
For easy understanding, please refer to fig. 4, a third embodiment of the verification method for parking access provided by the present application includes:

And step 302, the node server sends the verification default value to the parking user terminal, so that the parking user terminal returns a second encryption parameter, and the second encryption parameter is obtained by encrypting a private key and an input parameter corresponding to the parking user terminal through the verification default value.
After receiving the first encryption parameter sent by the parking user terminal, the node server sends a verification default value P to the parking user terminal, so that the parking user terminal encrypts a private key and an input parameter corresponding to the parking user terminal through the verification default value to obtain a second encryption parameter, and returns the second encryption parameter to the node server.
And step 303, the node server decrypts the first encrypted parameter and the second encrypted parameter respectively to obtain a first decryption result and a second decryption result, and sends a verification result obtained based on the first decryption result and the second decryption result to the parking user terminal, so that the parking user terminal accesses the node server to obtain the parking information when the verification result is successful.
The node server decrypts the first encrypted parameter to obtain a first decryption result, decrypts the second encrypted parameter through a public key corresponding to the parking user terminal to obtain a second decryption result, and sends a verification result obtained based on the first decryption result and the second decryption result to the parking user terminal, so that the parking user terminal accesses the node server to obtain parking information when the verification result is successful.
