It should be understood that although the terms first, second, third, etc. may be used in this specification to describe various information, these information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, the first information may also be referred to as second information, and similarly, the second information may also be referred to as first information, without departing from the scope of the present description. The word "if" as used herein may be interpreted as "at … …" or "at … …" or "responsive to a determination", depending on the context.
The embodiment of the disclosure provides a method for accessing a network, which is applied to terminal equipment to be added into the network, wherein the terminal equipment is equipment with a wireless access module, such as a wireless printer, a wireless network television, an intelligent camera sleeve, an intelligent door lock, a computer, a mobile phone and the like. As shown in fig. 1, the method includes:
s101, receiving a Beacon frame sent by an AP, and judging whether the Beacon frame carries a preset identifier and an encryption algorithm capability set or not;
s102, if the preset identifier is carried, sending a detection message to an AP (access point) sending the Beacon frame, wherein the detection message carries a first encryption algorithm selected from an encryption algorithm capability set;
s103, receiving a response message sent by the AP, wherein the response message carries first key information determined by the AP according to a first encryption algorithm in a detection message;
s104, accessing the AP according to the first key information and the SSID corresponding to the Beacon frame.
In this embodiment, the AP may periodically send a Beacon frame, and may carry a preset identifier and an encryption algorithm capability set by using a specific location in the Beacon, as shown in fig. 2, fig. 2 illustrates a partial structure of the Beacon frame, where the encryption algorithm capability set may be represented by using one byte, and the preset identifier may be represented by using an OUI.
In this embodiment, the preset identifier may be vendor information of the AP, for example, taking an AP of H3C as an example, the preset identifier carried in the Beacon frame sent by the AP is the OUI of H3C, that is, 00-0f-e2. In other embodiments, the preset identity may also include an identity indicating whether or not wireless automatic access is supported, such as the wireless automatic access capability (1 byte) in fig. 2 (i.e., in this embodiment, the preset identity includes both the OUI of H3C and the wireless automatic access capability).
In step S101, after the terminal device is powered on, the SSID may be scanned, that is, the Beacon frame sent by the AP may be received, and since the manner of the Beacon frame sent by the AP is similar to broadcast transmission, when all the terminal devices are within the coverage area of the AP, the Beacon frame may be received.
And the terminal equipment analyzes the Beacon frame to determine whether the Beacon frame carries a preset identifier and an encryption algorithm capability set.
In this embodiment, the encryption algorithm capability set may include a plurality of encryption algorithms for selection by the user, typically, symmetric encryption algorithms.
The symmetric encryption algorithm is also called a private key encryption algorithm, and the receiver and the sender use the same key, i.e. the encryption key and the decryption key are the same or equivalent. Symmetric encryption algorithms are used to encrypt information such as sensitive data.
The symmetric encryption algorithm mainly comprises: AES, DES, 3DES
DES (Data Encryption Standard): the data encryption standard has high speed and is suitable for occasions of encrypting a large amount of data.
3DES (Triple DES): based on DES, a piece of data is encrypted three times by three different keys, and the intensity is higher.
AES (Advanced Encryption Standard): the advanced encryption standard is the encryption algorithm standard of the next generation, and has high speed and high security level; AES is a block encryption algorithm using 128 as a block of blocks, which together with 128, 192 or 256 bit keys as inputs operate on a 4 x 4 array of bytes. AES is a very efficient algorithm, especially in 8-bit architecture, which results from its byte-oriented design. AES is suitable for 8-bit mini-singlechips or general 32-bit microprocessors and is suitable for implementation in dedicated hardware that enables its throughput (the number of encryption/decryption bits that can be reached per second) to be in the order of billions. Also, it is applicable to RFID systems.
In step S102, the terminal device selects one encryption algorithm from the encryption algorithm capability set as the first encryption algorithm, for example, the terminal device selects the AES algorithm from the encryption algorithm capability set as the first encryption algorithm.
The terminal equipment carries the selected first encryption algorithm in the detection message and sends the detection message to the AP, and because the Beacon frame sent by the AP carries the SSID, the terminal equipment can send the detection message to the AP according to the SSID.
After receiving the detection message sent by the terminal equipment, the AP can acquire a first encryption algorithm selected by the terminal equipment from the detection message, calculates a key according to the first encryption algorithm, takes the calculated key as first key information, and sends the first key information to the terminal equipment by utilizing a response message.
When the first key information is sent to the terminal device, the AP may choose to directly send the first key information to the terminal device, or may choose to encrypt the first key information, and send the encrypted first key information to the terminal device. For example, the AP side performs encryption processing by using AES, encapsulates the encrypted key in the response message, and then obtains the psk password by decrypting the encrypted key obtained from the response message by the terminal device.
After the terminal equipment acquires the first key information (including the decrypted first key information), the terminal equipment accesses the AP by using the first key information and the SSID, thereby completing network access work.
In another embodiment, in order to improve the security of the network, when the terminal device sends the probe packet to the AP, the probe packet may carry a security identifier, for example, the security identifier may be vendor information of the terminal device, where the vendor information may be represented by multiple bytes of OUI.
When the AP receives the probe packet carrying the security identifier and the first encryption algorithm, the AP may perform security authentication on the security identifier (vendor identifier), for example, when the security identifier is the vendor identifier, it may determine whether the vendor identifier is a legal vendor identifier (or a vendor identifier after negotiation), if so, generate the first key information and send the first key information to the terminal device, otherwise, do not perform subsequent processing.
According to the embodiment, through negotiation between the terminal equipment and the AP, the terminal equipment can acquire the secret key from the AP, and access the AP by using the secret key, so that the terminal equipment can automatically access the network, and the user is prevented from completing complicated network access steps.
The embodiment of the disclosure also provides a method for accessing a network, which is applied to an AP, as shown in fig. 3, and includes:
s301, a Beacon frame is sent, wherein the Beacon frame carries a preset identifier and an encryption algorithm capability set for indicating the access of terminal equipment;
s302, receiving a detection message sent by a terminal device, wherein the detection message carries a first encryption algorithm selected from an encryption algorithm capability set of a Beacon frame by the terminal device;
s303, determining first key information according to the first encryption algorithm, carrying the first key information in a response message, and sending the response message to the terminal equipment, so that the terminal equipment accesses the AP according to the first key information.
In step S301, the AP may periodically transmit a Beacon frame, a partial structure of which is shown in fig. 2.
