Detailed Description
Exemplary embodiments of the present application will be described in more detail below. While exemplary embodiments of the present application have been described, it should be understood that the present application may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
In this embodiment, the data information processing system includes a server and a vending machine (e.g., a juice maker), and the vending machine is networked with the server, so that the vending machine performs data information interaction with the server during normal operation, and performs series encryption and decryption on data information during the data information interaction process to avoid interruption, interception, tampering or counterfeiting of the data information, thereby eliminating security threats.
If the vending machine fails to receive the data information uploaded by the vending machine in the transaction process (under the condition that transaction completion information is not received) in the time exceeding the specified time due to unexpected power failure in the transaction process, the server can automatically encrypt and store the data information uploaded by the vending machine recently before power failure, specifically, the server carries out AES encryption and storage on the data information before power failure through an AES encryption standard, and the data information before power failure comprises the transaction information and the status information of the vending machine.
The AES encryption standard is used in an encryption process for converting plaintext into ciphertext, in which plaintext of every 16 bytes of data information, ciphertext, and round key are represented by matrices of 4x4, where the round key is parameters, which is data input during conversion of plaintext into ciphertext or conversion of ciphertext into plaintext.
The AES encryption process involves four operations, byte Substitution, row shifting, column obfuscation, and round key plus byte Substitution, the function of which is to map the internal bytes of the 4x4 matrix to another bytes through an S-box (Substistition-box), the function of row shifting is to achieve a permutation between the internal bytes of the 4x4 matrix, the specific operations are that the th row is left-shifted, the second row is left-shifted circularly by 1 byte, the third row is left-shifted circularly by 2 bytes, and the fourth row is left-shifted circularly by 3 bytes, the column obfuscation is specifically to substitute the column vector of the internal bytes of the 4x4 matrix with an arithmetic property over a field GF (28), wherein the field GF (28) is a set of bits over which addition, subtraction, multiplication, and division operations can be performed without the result exceeding the field, the round key plus is specifically to XOR the input of each round with the round key times in the encryption process.
The AES encryption standard undergoes packets of xor encryption (round key addition), then diffusion of the packet obfuscation (the other three stages), followed by xor encryption (round key addition), and so on, alternating such that the AES encryption standard is very efficient and secure.
The automatic vending machine uploads the data information to the server again after recovering the electric power, the server feeds back the encrypted data information before power failure to the automatic vending machine, and the series encryption and decryption can be carried out in the feedback process.
Because the data information stored by the server and uploaded recently before the power failure is encrypted, and the data information uploaded by the vending machine to the server after the power is recovered is not encrypted, the data information before the power failure and the data information after the power is recovered in the server cannot be mixed; and because the data information before power failure after the AES encryption is carried out by the AES encryption standard is subjected to three operations of byte replacement, row shifting and column obfuscation to provide obfuscation and nonlinear functions, the encrypted data information before power failure cannot be covered by the data information after power recovery. Because data information before the outage and data information after recovering electric power can not obscure, and encrypted data information before the outage in the server can not be covered, so after the automatic vending machine recovers electric power, the server feeds back that the data information before the outage in the automatic vending machine is accurate, namely the data information before the outage after AES decryption in the automatic vending machine is accurate. Because the data information before power failure comprises the transaction information and the state information of the vending machine, the vending machine can display the state information before power failure after decrypting the data information before power failure, and can recover incomplete transaction orders.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present application, and not for limiting the protection scope of the present application, and although the present application is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present application without departing from the spirit and scope of the technical solutions of the present application.
