Embodiment 1

[0040] figure 1 It is a flow chart of an ARP (Address Resolution Protocol, Address Resolution Protocol) spoofing detection method provided by Embodiment 1 of the present invention. Such as figure 1 As shown, the method specifically includes the following steps:

[0041] 101: Determine whether the electronic device is connected to the local area network. If the electronic device is not connected to the local area network, repeat step 101.

[0042] 102: If the electronic device is connected to a local area network, obtain connection information of the electronic device connected to the local area network. In this embodiment, the electronic device may be a portable electronic device, such as a mobile phone, a tablet computer, a notebook computer, and the like. The local area network may be a wireless local area network, such as a WiFi network. The connection information for the electronic device to access the local area network may include a gateway address and a subnet mask...

Embodiment 2

[0048] figure 2 It is a flow chart of the ARP spoofing detection method provided by Embodiment 2 of the present invention. Such as figure 2 As shown, the method specifically includes the following steps:

[0049] 201: Determine whether the electronic device is connected to the local area network. If the electronic device is not connected to the local area network, repeat step 201.

[0050] 202: Acquire connection information for the electronic device to access the local area network if the electronic device is connected to the local area network. In this embodiment, the electronic device may be a portable electronic device, such as a mobile phone, a tablet computer, a notebook computer, and the like. The local area network may be a wireless local area network, such as a WiFi network. The connection information for the electronic device to access the local area network may include a gateway address and a subnet mask, for example, the gateway address is 192.168.1.1, and t...

Embodiment 3

[0059] The first obtaining unit 301 is configured to obtain connection information for the electronic device to access the local area network when the electronic device accesses the local area network. In this embodiment, the electronic device may be a portable electronic device, such as a mobile phone, a tablet computer, a notebook computer, and the like. The local area network may be a wireless local area network, such as a WiFi network. The connection information for the electronic device to access the local area network may include a gateway address and a subnet mask, for example, the gateway address is 192.168.1.1, and the subnet mask is 255.255.255.0.

[0060] The first determining unit 302 is configured to determine an IP address that can be allocated by the local area network according to the connection information of the electronic device accessing the local area network. In this embodiment, the connection information for the electronic device to access the local are...

Abstract

The invention discloses an ARP (Address Resolution Protocol) spoofing detection method applied to an electronic device. The method comprises the steps of obtaining connection information, used for accessing a local area network, of the electronic device; determining an IP (Internet Protocol) address allocable for the local area network according to the connection information, used for accessing the local area network, of the electronic device; obtaining an IP address and a corresponding MAC (Media Access Control) address of a device actually existent in the local area network according to the IP address allocable for the local area network; and determining whether ARP spoofing exists in the local area network or not according to the IP address and the corresponding MAC address of the device actually existent in the local area network. The invention furthermore provides an ARP spoofing detection system. According to the method and the system, the ARP spoofing in the local area network can be quickly detected.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an ARP deception detection method and system. Background technique [0002] With the popularity of WiFi networks, people are used to accessing various WiFi networks when using smart terminals to enjoy the convenience of high-speed data access brought by WiFi networks. However, there are hidden security risks in various WiFi networks, the most common of which is It is ARP spoofing. [0003] ARP is the abbreviation of Address Resolution Protocol, that is, the address resolution protocol. The function of ARP is to provide dynamic mapping between IP (Internet Protocol, Internet Protocol) addresses and MAC (Media Access Control, Media Access Control) addresses, and transfer IP addresses (such as 32 1-bit IP address) into a 48-bit MAC address, so that IP packets can be correctly transmitted on the link. [0004] At the beginning of the design of the ARP protocol, the hosts in ...
