the service server 3 records a mobile terminal unique ID corresponding to the mobile terminal 1, the service server 3 is configured to perform decryption processing and message logic processing on encrypted message data, and the service server 3 is provided with a decryption unit 301 configured to perform decryption operation on the encrypted message data;
the authorization center 4 is provided with a cache 401 for storing the mobile terminal unique ID and the corresponding authorization code.
The above system is applied to practice to realize a mobile terminal APP secure interaction method, as shown in fig. 2, including the following steps:
s1, key agreement: the mobile terminal initiates a request for obtaining the authorization code, and obtains the authorization code through the APP server and the authorization center;
the mobile terminal sends an authorization code, acquires a unique ID corresponding to the mobile terminal through the service server and an authorization center, and records the unique ID in the service server;
specifically, the method comprises the following steps:
when a user operates on a mobile terminal H5 page, the mobile terminal initiates a request for obtaining an authorization code to an APP server;
then the APP server generates a mobile terminal unique ID corresponding to the mobile terminal, and sends the mobile terminal unique ID to an authorization center;
an authorization code corresponding to the unique ID of the mobile terminal is generated by the authorization center, the authorization code is returned to the mobile terminal through the APP server, and the mobile terminal can call back the authorization code to an H5 page;
then the user logs in the mobile terminal, and the mobile terminal sends the authorization code to the authorization center through the service server;
finally, the authorization center inquires and verifies the sent authorization code to obtain the corresponding unique ID of the mobile terminal, and returns the obtained unique ID of the mobile terminal to the service server, and the service server records the unique ID of the mobile terminal;
s2, message encryption and decryption: the mobile terminal sends message data, initiates a message encryption request, encrypts the message data by the APP server side and returns the encrypted message data to the mobile terminal;
the mobile terminal sends the encrypted message data to a service server, the service server performs decryption processing and message logic processing on the encrypted message data, and returns corresponding response information to the mobile terminal;
the APP server side is specifically spliced in real time to obtain a protection key based on the unique ID of the mobile terminal and the current timestamp so as to encrypt message data;
the service server specifically splices the unique ID of the mobile terminal and the current timestamp in real time to obtain a protection key so as to decrypt and restore the request message;
when encrypting or decrypting message data, the specific process is as follows:
intercepting characters with preset digits from the unique ID of the mobile terminal to obtain a first character string;
dividing the current timestamp serving as a public factor floor by the preset time to obtain a second character string;
splicing the first character string and the second character string to obtain a protection key;
and encrypting or decrypting the message data by combining the protection key and a triple data encryption algorithm.
The specific data interaction process of the embodiment applying the above technical scheme is shown in fig. 3, wherein when a key is agreed, a user member ID and a mobile terminal unique ID are uploaded and cached when logging in, and when encrypting and decrypting a message, a second half segment of a character string (containing 15 characters) is intercepted from the mobile terminal unique ID, and then the two are spliced to obtain a protection key by combining a current timestamp floor for 30 seconds. In the technical scheme, the protection key composition mode is generated by adopting a mode of combining the mobile terminal foreground and background access unique ID (namely session ID) and each intercepted fixed bit of the current timestamp.
When a service system needs to acquire the current login user of the APP, the APP simultaneously issues the current login user ID and the mobile terminal access unique ID 15 bits later through the authorization center and a token interaction mode through a background;
after the business system receives 15 bits after the mobile terminal accesses the unique ID, the first half section of the secret key is transmitted because the current mobile terminal foreground and background access unique IDs (session IDs) of the user access APP background are unchanged;
during encryption, the APP server accesses the second half section of the unique ID (session ID) and the current timestamp as a public factor floor through the foreground and the background of the mobile terminal for 30 seconds to generate a protection key, and encrypts data;
during decryption, the message is sent to the back end of the service system through the front end of the service system, the back half section of the unique ID accessed by the foreground and the background of the mobile terminal is reserved in the service system, the encryption key is recovered after splicing is completed for 30 seconds except through the timestamp floor, and the message is decrypted.
In summary, by means of the token authentication technology and the session technology, the APP system transmits the current login user to the three-party system through the background, cross-over is prevented, the privacy data of the user are protected, and therefore the page interaction safety of the APP embedded three-party system is guaranteed.
The invention realizes 'one-time pad' by self-research key acquisition algorithm and interactive process, and ensures the security of the key and the security of the process. The general process is as follows: the current time stamp (unit: second) is divided by 30 seconds, and the obtained value is spliced with the second half of the mobile terminal access unique ID (session) and then used as a symmetric key. The APP system transmits the mobile terminal access unique ID to the three-party system through a token exchange mechanism, and the key agreement is equivalently completed by combining an algorithm. When the embedded H5 page calls the APP client to provide an encryption method, the APP client calculates a secret key in real time through a session and the current time, and encrypts a message. And when the encrypted message is transmitted to the three-party system, the server of the three-party system splices the current cached mobile terminal access unique ID and the current time to be used as a secret key, and decrypts and restores the request message. When the decryption fails, the server of the three-party system decrypts the message again by using the current time of minus 30 seconds as a factor to ensure the availability, so that the embedded three-party system page is prevented from escaping outwards by combining a domestic cryptography algorithm (3DES algorithm-triple data encryption algorithm) and a secret key.
The invention only relates to calling the APP client JS and the background interface interaction, and does not relate to page jump and refresh, thereby ensuring the access fluency of the user.
