Apparatus and method for process authentication in redundant system

1. An apparatus for authenticating a process to be executed, comprising:

a hardware processor; and

a memory, wherein the memory stored therein computer-executable instructions which when executed by the processor causes the processor to:

select preset neighboring nodes from a plurality of neighboring nodes for the process to be executed, wherein the preset neighboring nodes selected are a subset of the plurality of neighboring nodes;

transmit, by each of the plurality of neighboring nodes, adjacent authentication data to an execution node of a redundant system in a network in response to a request from the execution node; wherein each of the plurality of neighboring nodes stores one piece of multiple pieces of the adjacent authentication data;

authenticate, by the execution node, the process to be executed by comparing local authentication data with one or more pieces of the multiple pieces of the adjacent authentication data received from only the selected preset neighboring nodes;

wherein the execution node comprises:

a local authentication data storage circuit for storing multiple process identifiers, wherein each of the multiple process identifiers is extracted based on one or more of a code area, a header and an extra flag of the process to be executed;

a local authentication data search circuit for extracting the local authentication data corresponding to the process to be executed from among the multiple process identifiers;

an adjacent authentication data search circuit for requesting and receiving the adjacent authentication data corresponding to the process to be executed from the plurality of neighboring nodes;

a process authentication circuit for authenticating the process to be executed by determining whether the local authentication data is equal to a subset of the multiple pieces of the adjacent authentication data; and

an execution circuit for executing the process to be executed when the process to be executed is successfully authenticated; and

wherein the execution node can be a neighboring node, and a neighboring node can be an execution node.

2. The apparatus of claim 1 , wherein the execution node further comprises a white list storage circuit for storing a list of processes that do not need to be authenticated, and

when the process to be executed is stored in the white list storage circuit, the execution circuit regards the process as being successfully authenticated and executes the process to be executed.

3. The apparatus of claim 1 , wherein each of the multiple process identifiers is maintained consistent throughout multiple executions of a process corresponding to a process identifier to be executed.

4. The apparatus of claim 1 , wherein the preset neighboring nodes are determined depending on the process to be executed.

5. A method for authenticating a process to be executed, comprising:

selecting preset neighboring nodes from a plurality of neighboring nodes for the process to be executed, wherein the preset neighboring nodes selected are a subset of the plurality of neighboring nodes;

transmitting, by each of the plurality of neighboring nodes, adjacent authentication data to an execution node of a redundant system in a network in response to a request from the execution node; wherein each of the plurality of neighboring nodes stores one piece of multiple pieces of the adjacent authentication data;

authenticating, by the execution node, the process to be executed by comparing local authentication data with one or more pieces of the multiple pieces of the adjacent authentication data received from only the selected preset neighboring nodes;

executing, the by execution node, the process to be executed when authentication of the process to be executed is successful,

wherein the execution node comprises:

a local authentication data storage circuit for storing multiple process identifiers, wherein each of the multiple process identifiers is extracted based on one or more of a code area, a header and an extra flag of the process to be executed;

a local authentication data search circuit for extracting the local authentication data corresponding to the process to be executed from among the multiple process identifiers;

an adjacent authentication data search circuit for requesting and receiving the adjacent authentication data corresponding to the process to be executed from the plurality of neighboring nodes;

a process authentication circuit for authenticating the process to be executed by determining whether the local authentication data is equal to a subset of the multiple pieces of the adjacent authentication data; and

an execution circuit for executing the process to be executed when the process to be executed is successfully authenticated; and

wherein the execution node can be a neighboring node, and a neighboring node can be an execution node.

6. The method of claim 5 , further comprising:

storing a list of processes that do not need to be authenticated; and

regarding the process to be executed as being successfully authenticated if the process to be executed is included in the list of processes.

7. The method of claim 5 , wherein each of the process identifiers is maintained consistent throughout multiple executions of a process corresponding to a process identifier to be executed.

8. The method of claim 5 , wherein the preset neighboring nodes are determined depending on the process to be executed.
