All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
An embodiment of the present invention provides a process authentication method, and fig. 1 shows a flowchart of an optional process authentication method according to an embodiment of the present invention, and as shown in fig. 1, the method includes:
step S11, determining a newly started process to be authenticated.
Specifically, the process to be authenticated may be a newly started process, and the starting of the process to be authenticated may be a related operation originated from a user or may be originated from an implanted malicious process.
It should be noted that, in the embodiment of the present invention, the authentication on the process may be that security authentication is requested by a newly started process to be authenticated. That is, after the system is powered on, the application program, i.e., the corresponding initialization data, is moved from the solid-state memory to the running memory, and the functions of monitoring messages and authenticating the process to be authenticated are started.
And step S12, respectively authenticating the security of the process to be authenticated through at least two authenticated processes.
Specifically, the number of the authenticated processes may be two or more, the authenticated process may be an initialization process stored in the server, and may be solidified in hardware inside the server, and the start of the process may be driven to be completed after the server bottom layer is powered on. And in the process of carrying out security authentication on the process to be authenticated, at least two authenticated processes carry out security authentication on the process to be authenticated respectively and independently.
In the embodiment of the invention, the security authentication is respectively carried out on the processes to be authenticated through at least two authenticated processes in the server, so that the problem of poor system security caused by the fact that the security authentication cannot be carried out on the malicious processes when the main controller is attacked in the mode that the main controller uniformly protects the authentication information is solved, the stealing and counterfeiting of data by the malicious processes are effectively prevented, and the technical effect of improving the security of the process authentication of the server is achieved.
In an alternative embodiment of the present invention, step S12 may include:
step S121, performing first authentication on the process to be authenticated through the at least two authenticated processes respectively to obtain at least two intermediate authentication results, where the intermediate authentication results include a trusted result and an untrusted result.
Specifically, after the authenticated process receives the authentication request of the newly started process to be authenticated, when the process to be authenticated is independently authenticated for the first time through each of the at least two authenticated processes, each authenticated process can obtain an intermediate authentication result, that is, each authenticated process can obtain a trusted result or an untrusted result.
Step S122, counting a percentage of the trusted result in the intermediate authentication result.
And S123, when the ratio of the credible results exceeds a preset threshold, determining that the process to be authenticated is safe.
Specifically, the preset threshold may be a preset value, for example, 50%, that is, when the percentage of the trusted result exceeds 50% in counting the intermediate authentication results, it is determined that the process to be authenticated is safe; and when the ratio of the unreliable result exceeds 50%, determining that the process to be authenticated is unsafe. That is, after the authenticated process performs the first authentication on the security of the process to be authenticated, the authentication result is broadcasted to other authenticated processes, and meanwhile, the broadcast of the intermediate authentication results of other authenticated processes is monitored. The statistical method may be that all the intermediate authentication results are counted, and when the percentage of the trusted results exceeds a preset threshold, the security of the process to be authenticated is determined. Similarly, when the untrusted result exceeds the preset threshold, it is determined that the process to be authenticated is unsafe.

and respectively comparing the first hash value with the second hash value to obtain the intermediate authentication result.
Specifically, when the newly started process to be authenticated requests security authentication, the process identifier, the digital signature and the public key of the process to be authenticated are broadcasted to each authenticated process, and each authenticated process authenticates the process to be authenticated according to the received process identifier, the digital signature and the public key. When each authenticated process authenticates the process to be authenticated, the process identifier is subjected to hash operation by using an MD4 algorithm, an MD5 algorithm, an SHS algorithm, or the like.
It should be noted that the digital signature of the process to be authenticated may be obtained by performing hash operation on the process identifier of the process to be authenticated to obtain a digital digest of the process to be authenticated, and encrypting the digital digest according to a private key of the process to be authenticated.
It should be further noted that, in the embodiment of the present invention, in the authentication process, the private key and the public key are used for encryption, so that the credibility and the uniqueness of the authentication process can be ensured, the information is prevented from being forged, and the credibility of the authentication is improved.

Compared with algorithms adopted by other hash operations, the MD4 algorithm occupies fewer bits, has higher operation speed and occupies smaller actual resources. Further, when the hash operation is performed by the MD4 algorithm, the probability of hash collision is lower.
In an optional implementation manner of the present invention, after the security of the process to be authenticated is authenticated by each of at least two authenticated processes, the method further includes:
when the process to be authenticated is determined to be safe, adding the process identification of the process to be authenticated to a list of authenticated processes.
Specifically, after determining that the process to be authenticated is safe, the process identifier of the process to be authenticated may be appended to the list of authenticated processes, that is, other processes to be authenticated may be security-authenticated by the process.
It should be noted that after determining that the process to be authenticated is safe, the process may establish related communication with the whole network process, otherwise, data cannot be acquired from any process.
Optionally, in any of the above embodiments, the at least two authenticated processes are distributed on at least two chips of the server new chipset.
In particular, the server may include one or more chipsets, any one of which is composed of a plurality of chips, and at least two authenticated processes are distributed over at least two chips of the chipsets. The number of authenticated processes can be set according to actual conditions, and the more the number of authenticated processes is, the more the authenticated processes are distributed on the chip, the higher the security of the system is. For example, when at least one authenticated process runs on each chip of the server chipset, the security of the system can be guaranteed to the maximum extent when a certain process or certain processes are attacked.
