Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description.
Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.
In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
Fig. 1 is a flow diagram of a method of modifying authentication information according to some embodiments of the present disclosure.
In step 102, in response to the request for modifying the authentication information, the optical network unit determines whether the authentication information exists in the optical network unit. For example, the authentication information may be a logical identification, or a logical identification and a password.
If so, i.e. in case of the authentication information itself, step 104 is performed. If not, i.e. in case of no authentication information of itself, the optical network unit may record the modification request.
In step 104, the onu checks whether the passive optical network port connected to the olt is in a normal operation state.
If yes, namely, under the condition that the passive optical network port is in a normal operation state, executing step 106; alternatively, the passive optical network port may be closed first, and then step 106 is performed. If not, i.e. the passive optical network port is not in a normal operation state, the optical network unit directly performs step 108.
In some implementations, the optical network units may be directly connected with the optical line terminal. In other implementations, the optical network units may be indirectly connected to the optical line terminal, for example, through passive devices such as optical fibers, passive optical splitters, and the like.
As one example, whether the passive optical network port is in a normal operating state may be determined according to the operating state parameter. For example, in the case that the operation state parameter is 1, it indicates that the passive optical network port is in a normal operation state; when the operation state parameter is 0, it indicates that the passive optical network port is not in a normal operation state.
In step 106, the onu determines whether the requester of the modification request belongs to the passive optical network system in which the onu is located.
If so, namely, in the case that the requester of the modification request belongs to the passive optical network system in which the optical network unit is located, executing step 108; alternatively, the port of the passive optical network is closed first, and then step 108 is performed. If not, i.e. in case the requester of the modification request does not belong to the passive optical network system in which the optical network unit is located, step 110 is performed.
In some embodiments, the onu may determine whether the requester of the modification request belongs to the passive optical network system in which the onu is located according to the following manner: first, the onu requests the requester of the modification request to input authentication information, where the authentication information is information related to the onu. Then, under the condition that the information to be verified input by the requester passes verification, the requester is judged to belong to a passive optical network system where the optical network unit is located; and under the condition that the information to be verified input by the requester is not verified, the optical network unit judges that the requester does not belong to the passive optical network system in which the optical network unit is positioned.
In step 108, the onu modifies its authentication information.
In some embodiments, the optical network unit does not close the passive optical network port before modifying the authentication information of itself, but closes the passive optical network port after modifying the authentication information of itself. Then, the optical network unit authenticates with the modified authentication information. After the authentication is passed, the optical network unit restarts the passive optical network port to perform normal service. Such an implementation may reduce the time that normal traffic is affected.
In step 110, the onu does not modify its authentication information.
In the above embodiment, in response to the request for modifying the authentication information, the onu modifies the authentication information of the onu when the passive optical network port is in a normal operating state and the requestor belongs to the passive optical network system, or does not modify the authentication information of the onu. This reduces the risk of remote malicious modification of the authentication information of a normally operating optical network unit.
In some embodiments, the information related to the optical network unit includes a plurality of items of information, for example, WIFI information stored by the optical network unit, SSID (Service Set Identifier) of the optical network unit, and the like. In this case, it is possible to randomly select one or more pieces of information from a plurality of pieces of information and then determine a partial content of the randomly selected information as the authentication information, or determine the entire content of the randomly selected information as the authentication information. The verification mode can improve the passing difficulty of verification and reduce the possibility of error modification and malicious modification.
In some implementations, the information randomly selected by the onu may be a string, and the authentication information may be a character of a random bit of the string. For example, the information randomly selected by the optical network unit is a WIFI password. Assuming that the WIFI password is 2a3b4c5n680, the requesting party is randomly required to input part of the content of the WIFI password, for example, the first, fifth, and eighth digits of the WIFI password. If the verification information to be authenticated submitted by the requester is 24n, the verification information to be authenticated passes the verification; and if the verification information to be authenticated submitted by the requester is not 24n, the verification information to be authenticated does not pass the verification. The verification mode can further improve the verification difficulty, so that the possibility of error modification and malicious modification is further reduced.
In the present specification, the embodiments are described in a progressive manner, and each embodiment focuses on differences from other embodiments, and the same or similar parts in each embodiment are referred to each other. For the embodiment of the optical network unit, since it basically corresponds to the method embodiment, the description is relatively simple, and for relevant points, reference may be made to part of the description of the method embodiment.

The first determining module 201 is configured to determine whether the optical network unit has the authentication information in response to the modification request of the authentication information.
The checking module 202 is configured to check whether a passive optical network port of the onu connected to the olt is in a normal operation state in case that the onu has the authentication information.
The second determining module 203 is configured to determine whether the requester of the modification request belongs to the passive optical network system where the optical network unit is located, in case that the passive optical network port is in a normal operation state.
The processing module 204 is configured to modify the authentication information of the optical network unit when the requester belongs to the passive optical network system in which the optical network unit is located; and under the condition that the requester does not belong to the passive optical network system where the optical network unit is located, the authentication information of the optical network unit is not modified.
In the above embodiment, in response to the request for modifying the authentication information, the onu modifies the authentication information of the onu when the passive optical network port is in a normal operating state and the requestor belongs to the passive optical network system, or does not modify the authentication information of the onu. This reduces the risk of remote malicious modification of the authentication information of a normally operating optical network unit.
