Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
In the description of the present specification, the terms "comprising," "including," "having," "containing," and the like are used in an open-ended fashion, i.e., to mean including, but not limited to. Reference to the description of the terms "one embodiment," "a particular embodiment," "some embodiments," "for example," etc., means that a particular feature, structure, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the application. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example. Furthermore, the particular features, structures, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. The sequence of steps involved in the embodiments is for illustrative purposes to illustrate the implementation of the present application, and the sequence of steps is not limited and can be adjusted as needed.
Because the capability of network transmission security attack is continuously improved, the vulnerability of message data protection is made up, which is extremely important. The shorter the updating period of the message protection code is, the stronger the attack defense capability of the message protection code is, and the greater the difficulty of the message data to be cracked is.
The inventor finds that the updating of the message protection code needs to be realized by upgrading the software program version at the message transceiving terminal equipment, so that the realization difficulty is higher and the investment cost is higher. Therefore, the embodiment of the invention provides a message protection scheme based on a set of self-defined virtual instruction set and a related virtual instruction compiler and virtual instruction interpreter, so that a message protection code can be flexibly upgraded under the condition of not upgrading the software program version of the message protection scheme, and the safety protection capability of message transmission is improved.
It should be noted that, in the embodiment of the present invention, the virtual instruction set may include a mapping relationship between a group of virtual instructions and a message protection code, and the virtual instruction compiler is configured to compile a message protection original code into a virtual instruction program code; the virtual instruction interpreter is used for interpreting the virtual instruction program code (namely byte code) to obtain machine code (namely computer executable code) and executing the machine code. It should be noted that the message protection code for protecting the message original text can be converted into the message protection code executable by the computer only by the interpretation processing of the virtual instruction interpreter after being compiled by the virtual instruction compiler.
In addition, it should be further noted that the embodiment of the present invention is directed to protecting a scheme for compiling and interpreting a message protection code through a virtual instruction set and a related virtual instruction compiler and interpreter, and a specific definition of the virtual instruction set is determined according to an actual situation as long as the virtual instruction set can be compiled and interpreted through a corresponding compiler and interpreter.
Optionally, the message protection code for performing message protection on the message original text in the embodiment of the present invention may be, but is not limited to, an encryption/decryption code for encrypting and decrypting the message original text.
Fig. 1 is a schematic diagram of a message protection scheme based on a virtual instruction provided in an embodiment of the present invention, and as shown in fig. 1, a virtual instruction compiler is invoked to compile a message protection byte code (i.e., an encrypted code for encrypting a message original text or a decrypted code for decrypting the message original text) into a message protection byte code (a virtual instruction byte code corresponding to the encrypted code or a virtual instruction byte code corresponding to the decrypted code); then the code is interpreted into executable machine code (computer executable encrypted code or decrypted code) by the virtual instruction interpreter and executed. The embodiment of the invention refers to the codes executable by the computer as machine codes, and the virtual interpreter provided by the embodiment of the invention can directly convert the virtual instruction program codes compiled by the virtual compiler into codes executable by the computer and execute the codes.
Generally, a message protection code for encrypting and decrypting a message original text is a C language code, and is compiled by a virtual instruction compiler to obtain a message protection byte code, and then is interpreted by a virtual instruction interpreter, so that a machine code corresponding to the message protection code can be directly obtained and executed.
Namely, after the encrypted code is compiled by the virtual compiler to obtain the encrypted byte code, the encrypted byte code is interpreted and executed by the virtual instruction interpreter; and after the decryption code is compiled by the virtual compiler to obtain the decryption byte code, the decryption operation is interpreted and executed by the virtual instruction interpreter.
It should be noted that since the message protection bytecode compiled by calling the virtual instruction compiler on the message protection code can only be executed by the virtual instruction interpreter, a layer of protection can be provided for the message protection code. The virtual instruction compiler and the virtual instruction interpreter in the embodiment of the invention can provide a safe reinforced operating environment for executing message processing, thereby improving the data safety of a message transceiving end.
The embodiment of the invention forms a set of flexible and complete message transmission protection mechanism by a user-defined virtual instruction set, a safety reinforced virtual instruction interpreter environment and a flexibly updated message protection byte code, and provides two complete technical schemes.

The message sending end transmits the message protection byte code and the message after protection processing to the message receiving end through one or more times of communication. The message receiving end is also provided with a virtual instruction interpreter, and the message after protection processing is reversely processed by interpreting and executing the message protection byte code to obtain the final message original text. The message security transmission scheme based on the virtual instruction, which is provided by the embodiment of the invention and is shown in fig. 2, can flexibly upgrade message protection codes according to security requirements.

In addition, it should be further noted that, in the embodiment of the present invention, a specific manner of message protection processing may be flexibly implemented according to business security requirements, and a manner generally adopted is to perform encryption/decryption protection processing on a message.

③ calls the virtual instruction compiler to compile the original code of the decryption algorithm dSC (corresponding to the encryption algorithm eSC) to get the decrypted bytecode dBC.
④ the decrypted bytecode dBC and the message M' constitute a new message, which is sent to the message receiver via one or more communications.
(II) the message receiving device (message receiving end) receives and decrypts the message:

②, the decryption bytecode dBC is checked and the update is successful.
