The embodiments of the present application will be described in detail below with reference to the accompanying drawings.
In the prior art, in order to prevent the network password of the wireless network from being leaked, a user may update the network password of the wireless network at intervals, and it is very important to improve the security of the network password, and in addition, the time for updating the network password by each device is not completely consistent with the hot spot updating network password, and all devices connected with the hot spot (such as a router) are necessarily required to be disconnected in the updating process, so that the use experience is poor.
Some embodiments of the present disclosure provide an updating method for a network password, where the updating method for a network password may be used in a hotspot device or terminal, for example, a router or a mobile phone, as shown in fig. 1, fig. 1 is a flowchart of the updating method for a network password in an embodiment of the present disclosure, and includes the following steps:
s11: calculating a new password corresponding to an update time point by using an update algorithm with an original password of a target network before the update time point as a parameter;
in this embodiment, the network password being used by the target network before the update time point is the original password, and the network password of the target network needs to be updated at the update time point;
s12: updating the network password of the target network by using the corresponding new password at the updating time point;
in some embodiments, the new password may be used as the network password for the target network. In this embodiment, the updated new password depends on the original password and the update algorithm before updating, so that when updating, the user can calculate the updated network password on the device used by the user by himself only needing to know the original password, the update algorithm and the update time point before updating, and automatically update the network password at the update time point, without informing the user of the updated network password by other devices, and by reducing transmission of the updated network password, the network password can be prevented from being leaked as much as possible, the security and the confidentiality of the network password are improved, and unauthorized devices are enabled to be disconnected from the target network.
In some embodiments, during a period from a first duration before the update time point to the update time point, the original password and a new password corresponding to the update time point are simultaneously used as the network password of the target network; and/or during a second time period from the updating time point to the time point after the updating time point, simultaneously using the original password and the new password corresponding to the updating time point as the network password of the target network. In some embodiments, the first duration and the second duration may be, for example, 5 minutes, 3 minutes, or 1 minute, at this time, before and/or after any update time point, the target network simultaneously uses the original password and the new password corresponding to the update time point as the network password, that is, the target network may be connected to the target network through any one of the original password and the new password corresponding to the update time point, which is equivalent to setting a buffer period for updating the password, and when the device using the network updates the network password in advance and/or delays updating the network password, the connection of the network is not disconnected, so that the use experience of the user is improved, because the connection with the network is not disconnected, the update period for updating the network password is greatly shortened, and even the update period is in the order of minutes.
To facilitate understanding of the network updating method proposed by the embodiment of the present disclosure, referring to fig. 2, a detailed description is made on the network password updating method proposed by the embodiment of the present disclosure, as shown in fig. 2, where the coordinate axis shown in fig. 2 is time, assuming that the current time is the time point identified by T0 in fig. 2, the target network password at the current time is the original password P0, and the first updating time point is the time point at which T1 in fig. 2 is located, step S11 is first performed to determine the new password P1, at the first updating time point T1, the network password of the target network is updated with P1, if P0 is invalidated from the time point T1 according to the prior art, P1 will become the network password of the target network, however, in some embodiments of the present disclosure, a first time length Δ T1 and a second time length Δ T2 are set, a time period from T1 to Δ T1 to T1 shown in fig. 2, and/or a time period from T1 to Δ T2 +, using both P0 and P1 as the network password of the target network, using P1 as the network password of the target network during the time period from T1+ Δ T2 to the next update time point corresponds to letting P1 take effect in advance as the network password before the first update time point T1 while keeping P0 valid, and letting P0 extend for a period of time after the first update time point T1 while keeping P1 valid.
In the prior art, when a network password is updated, the hotspot device and the device using the network cannot achieve real time synchronization, and therefore after the update time is up, a part of devices using the network are inevitably disconnected from the hotspot device, and poor use experience is caused.
In some embodiments of the present disclosure, the number of the update time points is at least 2, and the new password corresponding to any one of the update time points is an original password before a next update time point. Illustratively, referring to fig. 2, as shown in fig. 2, there are a first update time point T1 and a second update time point T2, the network password being used by the target network before T1 is the original password P0 for T1, the new password corresponding to the first update time point T1 is P1, and after the network password of the target network is updated with P1, the P1 is the original password of the target network corresponding to the second update time point T2 during the period from T1 to T2. Similarly, the new password corresponding to T2 will also be the original password corresponding to the next update time point after T2.
In some embodiments of the present disclosure, the number of the update time points is at least 2, and the calculating a new password corresponding to the update time point by using an update algorithm includes: and calculating each new password corresponding to each updating time point by adopting an updating algorithm. Or, calculating a new password corresponding to the update time point by using an update algorithm, including: and calculating the new password corresponding to the updating time point in a third time before the updating time point, or calculating the new password corresponding to the updating time point at the updating time point. That is, in this embodiment, the new passwords corresponding to the N update time points may be calculated and stored at one time, or may be calculated only when the password needs to be updated, so as to reduce resource occupation.
To better explain the embodiment, please refer to fig. 2, the second update time point T2 is the next update time point after the first update time point T1, in the embodiment, the new password P2 corresponding to T2 is determined by the new password P1 corresponding to T1, and so on, the new password corresponding to any update time point is determined by the new password corresponding to the previous update time point before the update time point. Therefore, in this embodiment, as long as the device used by the user to connect to the target network knows any network password, update algorithm, and update time point, the device of the user can automatically calculate the network password corresponding to each update time point, and therefore, the device of the user can permanently obtain the network password updated each time only by performing data transmission on the device of the user once, and does not need to perform data transmission when updating the network password each time, so that the concealment and reliability of the network password are improved, and meanwhile, the validity of the network password can be ensured. In some embodiments of the present disclosure, during a first duration before and/or a second duration after any update time point, the new password corresponding to the update time point and the original password before the update time point are both used as the network password of the target network.
In some embodiments of the present disclosure, the network password updating method is executed every preset updating period, and the network password of the target network is updated. The preset update period may be, for example, one day, one week, or one month. The network security is improved by periodically changing the network password.
In some embodiments of the present disclosure, the update algorithm is an irreversible algorithm. Therefore, lawless persons can be prevented from reversely calculating the updating algorithm through one or more network passwords, and the safety of the updating algorithm is guaranteed. In some embodiments, the irreversible algorithm includes a hash algorithm, and the hash value depends on an input parameter of the hash algorithm and has uniqueness, so that the new password may be the hash value of the original password, or the new password is an n-bit character in the hash value of the original password, for example, to improve the security of the network password, n may be selected as an integer not less than 32.
In some embodiments of the present disclosure, before calculating a new password corresponding to an update time point by using an update algorithm with an original password of a target network before the update time point as a parameter, the method further includes: setting an initial sequence, calculating by using an updating algorithm with the initial sequence as a parameter to obtain an initial network password, wherein the initial network password is an original password before the earliest updating time point, and the first updating time point calculates by using the updating algorithm to obtain a new password corresponding to the first updating time point with the initial network password as a parameter. In this embodiment, the initial sequence is set, and the initial network password is obtained by using the update algorithm, so that the initial sequence and the update algorithm may be sent to the trusted device only at the beginning, instead of directly sending the initial network password to the trusted device, thereby improving the security and the imperceptibility of the network password.
In some embodiments of the present disclosure, taking an original password of a target network before an update time point as a parameter, and calculating before a new password corresponding to the update time point by using an update algorithm, further includes: and transmitting the original password, the updating time point and the updating algorithm to at least one target terminal. In this embodiment, the target terminal is a trusted terminal, for example, a mobile phone of a user, a tablet, and the like, and the content is sent to the target terminal in advance, so that the target terminal can automatically calculate an updated new password and automatically update the network password at an update time point, thereby ensuring that the connection with the target network is not disconnected when the network password is updated, improving user experience, reducing the possibility of network password leakage, and reducing user loss. In some embodiments of the present disclosure, the original password, the update time point, and the update algorithm are stored in a secure partition of the target terminal to prevent information from being stolen by malicious software.
In order to better explain the beneficial effects of the network password updating method proposed by the present disclosure, a specific embodiment is described below. In this embodiment, the wireless router as the hot spot executes the network password updating method, the mobile phone of the user is used as a trusted device authorized by the wireless router, i.e. a target terminal, the network password currently used by the target network transmitted by the wireless router is the original password P0, the mobile phone of the user previously obtained an initial sequence, an updating algorithm and each updating time point from the wireless router, or previously obtained the original password, the updating algorithm and each updating time point, the wireless router calculates a next updating time point, i.e. a new password corresponding to the first updating time point, here taking the updating algorithm as a hash algorithm as an example, the new password corresponding to the first updating time point may be n bits in the hash value of the original password P0, the wireless router updates the network password of the target network to the new password corresponding to the first updating time point at the first updating time point, but in the first time length before the first updating time point and the second time length after the first updating time point, the original password and the new password are used simultaneously, which is equivalent to setting the buffering time. The mobile phone of the user calculates a new password based on an updating algorithm, and the new password is adopted to be connected with the target network at the first updating time point, and the wireless router sets the buffer time, so that even if the time of the mobile phone of the user and the time of the wireless router are asynchronous, the first updating time point determined by the mobile phone of the user and the wireless router has slight difference, the mobile phone of the user can not be disconnected with the target network, the period for updating the network password can be shortened, meanwhile, the network password does not need to be communicated with the wireless router every time, the safety of the network password is ensured, an unauthorized terminal can be disconnected with the target network when the network password is updated, and the network safety of the user is ensured.
In some embodiments of the present disclosure, as shown in fig. 3, an embodiment of the present disclosure further provides an apparatus for updating a network password, including:
a calculating unit 10, configured to calculate, by using an original password of a target network before an update time point as a parameter, a new password corresponding to the update time point by using an update algorithm;
