Description

Group test authentication encryption method, verification decryption method and communication method
Technical Field
The invention relates to the field of information security, in particular to a group test authentication encryption method, a group test verification decryption method and a communication method.
Background
Authentication encryption (Authenticated Encryption) is a cryptographic scheme that provides both encryption and authentication functions. Encryption ensures confidentiality of data, namely plain text information cannot be revealed, authentication ensures integrity of the data, namely transmitted data is ensured not to be tampered by adversaries, and information sources can be confirmed. The encryption algorithm of the authentication encryption scheme is input into a secret key, an initial vector, associated data and a plaintext, wherein the associated data is data which does not need to be encrypted and transmitted and only needs to be guaranteed not to be tampered, and the plaintext is data which needs to be encrypted and transmitted and is output into a ciphertext and a message authentication code; the input of the decryption algorithm is a secret key, an initial vector, associated data, a ciphertext and an authentication code, the decryption algorithm regenerates the message authentication code, compares the message authentication code with the received message authentication code, judges whether the ciphertext is effective or not, and generates and outputs a corresponding plaintext if the ciphertext is consistent with the received message authentication code.
The Group Testing (Group Testing) method originates from blood sample Testing during the second combat phase-how to quickly find an infected person from a large number of blood samples with as few tests as possible. Group tests are classified into adaptive and non-adaptive, the adaptive group test is generally a multi-step group test, and the latter group policy depends on the previous detection result; the non-adaptive group test only needs one step to perform a plurality of tests, and the tests can be performed simultaneously, so that the invention is more beneficial to application in practical problems, and therefore, the invention uses the non-adaptive group test. This approach is generally characterized by a group test matrix.
During data transmission, a user may generate a large number of short messages, such as adding, deleting, changing, withdrawing and the like during editing of an online document, each operation can be regarded as a short message, and during communication with a server, an initial vector and an authentication code generated during authentication encryption processing of the messages bring about a large number of data expansion, so that the efficiency of network transmission is greatly affected.
A plurality of short messages are combined into a long message and then are processed by an authentication encryption algorithm, so that the data expansion of an authentication code can be reduced to a great extent, but when decryption verification fails, the problem of which short message is out cannot be determined, and retransmission of all messages is caused. If the location of the message error can be detected with as little data expansion as possible, the amount of network data transmission will be greatly reduced.
In view of this, how to reduce data expansion and detect the location of error messages at the same time in authentication encryption is a technical problem that needs to be solved at present.
Disclosure of Invention

The beneficial effects of the technical scheme are as follows: the general group test authentication encryption method is provided, and the number of the final message authentication codes is far smaller than the number of the messages, so that the data expansion can be effectively prevented, and the data transmission quantity during communication is reduced. For example, in an industrial control system, a large amount of data needs to be frequently transmitted, and the method can be used for carrying out group test on authentication encryption data to be transmitted by a transmitting end, so that the communication efficiency can be effectively improved.
Further, the generating ciphertext and the corresponding message authentication code specifically includes: and the sending end and the receiving end share a group of keys K 1, and encrypt the plaintext and the associated data by calling an encryption algorithm of the authentication encryption scheme according to the initial vector to generate a ciphertext and a corresponding first initial message authentication code.

Further, the generating the final message authentication code specifically includes: and the sending end and the receiving end share another group of secret keys K 2, and the first final message authentication code is obtained by calling an adjustable block cipher to encrypt the intermediate value according to the intermediate value.
The beneficial effects of the steps are as follows: the message authentication code is generated by using the adjustable block cipher, so that the method has higher security and is simple and universal.
Further, the authentication encryption scheme adopts a CCM algorithm.
The invention also provides a group test verification decryption method, which is applied to a receiving end and comprises the following steps:

Encrypting the intermediate value, generating a second final message authentication code, comparing the received first final message authentication code, determining the position of an invalid ciphertext according to a group test method, and outputting the rest corresponding plaintext.
The beneficial effects of the technical scheme are as follows: a general group test verification decryption method for detecting the location of an error message while reducing the amount of data transmission at the time of communication is provided. The purpose of checking the validity of the ciphertext can be achieved by transmitting a small number of message authentication codes. And if the calculated message authentication code is legal, indicating that the data received by the receiving end is not tampered, otherwise, indicating that the data is tampered.
Further, the generating the plaintext and the corresponding second initial message authentication code specifically includes: and the receiving end and the transmitting end share a group of keys K 1, and the received ciphertext is decrypted by calling a decryption algorithm of an authentication encryption scheme according to the received initial vector and the associated data to generate a plaintext and a corresponding second initial message authentication code.

S2, generating intermediate values X j, j=1, 2, … and t by using a group test matrix according to the first initial message authentication code;
S3, sharing another group of secret keys K 2 with the receiving end, and generating a first final message authentication code T= (T 1,T2,…,Tt) according to the intermediate value X j, j=1, 2, … and T, wherein T is less than or equal to m; and (N, (A 1,C1),…,(Am,Cm),(T1,T2,…,Tt)) is transmitted to the receiving end.
Compared with the prior art, the embodiment provides a universal group test authentication encryption method, which is used for reducing the data transmission quantity during communication, in particular to reducing the quantity of initial vectors N and message authentication codes S. Fig. 2 shows a schematic diagram of a group test authentication encryption method according to embodiment 1 of the present invention.
Example 2
Optimizing on the basis of embodiment 1, step S1 further comprises:
S11. the transmitting end shares the secret key K 1 with the receiving end, encrypts m groups of messages (a i,Pi), i=1, 2, …, m, and generates a ciphertext and a corresponding first initial message authentication code (C i,Si), i=1, 2, …, m, by the following formula:
ε(K1,N||i,Ai,Pi)＝(Ci,Si),i＝1,…,m

Preferably, the authentication encryption scheme may be a CCM algorithm.
The step S2 further includes:

illustratively, when t= 9,m =15, the group test matrix may be selected as:
Each row of the matrix Q 9×15 represents the packet information of the intermediate value, and if a ji =1, the j-th packet includes S i, whereas a ji =0 represents that the j-th packet does not include S i. Finally, the 15 message authentication codes S i can be divided into 9 groups, and the values of the groups are xored to obtain X j, j=1, 2, …,9. The error detection capability of the group test matrix is determined by the maximum value of d in the property that the group test matrix is bit-wise or contains no other columns for any no more than d columns. The error detection capability of the matrix Q 9×15 is 1, which means that if 1 ciphertext data is tampered with in transmission, the error position can be found accurately, and if more than 1, the error position cannot be found accurately.
The step S3 further includes:
