Description
Technical Field
The present disclosure relates to the field of communications, and in particular, to an access control method and apparatus.
Background
Nowadays, in order to improve the use experience of users, many product manufacturers optimize products and provide a plurality of convenient modes. For example, when the automobile is started without a key, the intelligent entrance guard/the intelligent home is used, password/fingerprint payment is not required, for example, partial bank cards/credit cards, WeChat and Paibao are used, a lot of bank cards adopt a small-amount password-free payment function, and bank cards used by ETC popularized nationwide in the year are also generally small-amount password-free payment (the bank defaults to open the small-amount password-free), for example, some bank cards marked with the word 'flash payment'.
The products in the above fields provide convenience, and meanwhile, there are many safety risks, such as: various attack/cracking tools such as long-distance card reading at the limit of an NFC protocol, entrance guard system intrusion, processor system decryption, automobile key relay, bank card information acquisition and the like easily cause privacy information leakage and property loss, and even threaten personal safety.
For example, the keyless start of an automobile is taken as an example, the keyless start is widely applied to various automobile brands in the global range at present, and automatic unlocking can be realized through simulation to drive the automobile away. The working principle is as follows: one person adopts wireless signal relay equipment or simulator, and the telecar key that is close to the car owner reads key information, and another person uses key information simulation to be the car key through the simulator near car owner's car, lets the car of car owner with just in the front of as the car key, will automatic unblock. The wireless signal relay equipment or the simulator generally has functions of wireless signal amplification and one-way/two-way transmission, and the two-way transmission refers to that some automobile systems interact with automobile keys to acquire data such as rolling codes and the like so as to unlock automobiles.
For another example, bank card/credit card copying and bank card swiping payment are similar, and some bank cards have no password (for example, for foreign people), can copy the information of the stolen card by using equipment to be close to the bank cards, and swipe the card directly at the POS machine or swipe the card at a remote POS machine.
For another example, the same problem exists in the ETC popularized nationwide in this year, and the bank card used by the ETC generally sets a small amount of secret-free payment through toll stations and the like, so that the bank card or the credit card is simulated to be directly embezzled after information is stolen.
The above security problem also exists with the secret-free payment method of WeChat/Payment.
In addition, the entrance guard card/induction card (intelligent door lock) also has potential safety hazard, especially after 5G begins to use, the transmission speed is faster, for example, an illegal user swipes/copies the intelligent key information of a legal user in the United states, and the family of the legal user in China can be directly opened.
In summary, the various access methods in the prior art facilitate user operations and have a great security hole, which is easy to bring security problems to users.

Detailed Description
Embodiments of the present invention will now be described with reference to the drawings, wherein like parts are designated by like reference numerals. The embodiments described below and the technical features of the embodiments may be combined with each other without conflict.
FIG. 1 is a schematic flow chart diagram illustrating one embodiment of an access control method of the present invention. The access control method of the embodiment of the invention is applied to the first terminal equipment.
As shown in fig. 1, the access control method according to the embodiment of the present invention includes:
s101, receiving second verification information from second terminal equipment;
s102, obtaining a first time length between the second verification information is sent to the second terminal device and received;
s103, comparing the first time length with a preset time length, and determining whether to allow the second terminal equipment to access the first terminal equipment according to the comparison result.
In the embodiment of the invention, the first terminal device is an accessed device, the second terminal device is an accessed device, and the accessed device can be connected to the accessed device to request to access. The accessed device can perform the operation requested by the access of the access device after confirming the identity of the access device according to the information sent by the access device.
In some embodiments of the present invention, when requesting to access the first terminal device, the second terminal device may send an access request to the first terminal device as second authentication information, where the second authentication information may include, for example, device identification information of the second terminal device and authentication information such as an agreed key, a character string, and encrypted data. After the first terminal device receives the second verification information, besides confirming the identity of the second terminal device according to the device identification information and the verification information, the first terminal device also obtains the time length from the time when the second verification information is sent by the second terminal device to the time when the second verification information is received by the first terminal device as a first time length, and compares the first time length with a preset time length.
Here, the predetermined time period is determined in advance according to a time period required for information to be transferred between the first terminal device (or another device same as the first terminal device) and the second terminal device (or another device same as the second terminal device) when the first terminal device and the second terminal device are directly connected in a communication manner, that is, the predetermined time period in the embodiment of the present invention corresponds to a reasonable time period required for information to be transferred in a single direction when the first terminal device and the second terminal device are directly connected in a communication manner. Alternatively, a reasonable error range may also be considered when setting the predetermined time.
And after the first terminal equipment compares the obtained first time with the preset time, determining whether the second terminal equipment is allowed to access the first terminal equipment at this time according to the comparison result. When the first time length is less than or equal to the predetermined time length, the first terminal device confirms that the access of the second terminal device is legal, allows the access of the second terminal device to the first terminal device at this time, and can perform the operation requested by the access of the second terminal device at this time, for example; and when the first time length is longer than the preset time length, the first terminal equipment confirms that the access of the second terminal equipment is illegal, and refuses the access of the second terminal equipment to the first terminal equipment.
The following briefly describes the case where the second terminal device has legitimate access and illegitimate access to the first terminal device, with reference to fig. 3 and 4.
As shown in fig. 3, in the case of a legitimate access, a direct communication connection is established between a first terminal device a and a second terminal device B. Assuming that the maximum time required for the measured signal to be transmitted from the second terminal device B to the first terminal device a through the direct communication connection is 1ms, the predetermined time period may be set to 1 ms. Under the condition that whether direct communication exists between the second terminal device B and the first terminal device A is unknown, if the first time length obtained by the first terminal device A is not more than the preset time length of 1ms, the direct communication connection between the second terminal device B and the first terminal device A can be confirmed, and the current access of the second terminal device B is considered as legal access.
Alternatively, a reasonable error range may also be taken into account when setting the predetermined time period. For example, taking an error of 0.1ms as an example, the predetermined time period may be set to 1.1 ms; alternatively, the predetermined period may be set to 1.15ms, for example, with an error of 15%, and so on.
As shown in fig. 4, in the case of an illegal access, an indirect communication connection is established between the first terminal device a and the second terminal device B through the emulator C and the reader D, the reader D illegally reads information of the second terminal device B and transmits the information to the emulator C, the emulator C simulates that the second terminal device B establishes a communication connection with the first terminal device a based on the illegally read information, and transmits second authentication information from the second terminal device B to the first terminal device a. After the first terminal device A receives the second verification information, the first time length between the second verification information being sent from the second terminal device B and the second verification information being received by the first terminal device A is obtained, when the first time length is compared with the preset time length, the result is that the first time length is longer than the preset time length, the fact that the second terminal device B is not in direct communication connection with the first terminal device A can be confirmed, the access of the second terminal device B is considered as illegal access, and the access request is rejected.
According to the embodiment of the invention, whether the access from the second terminal equipment is legal or not can be accurately judged by acquiring the time length between the sending and the receiving of the verification information and comparing the time length with the preset time length, so that illegal access can be effectively dealt with, and the safety level of access operation is improved while the convenience of user operation is kept.
In the embodiment of the invention, the first terminal equipment can be an intelligent door lock, and the second terminal equipment is an electronic key device; or, the first terminal device may be a door lock control device of an automobile, and the second terminal device may be an electronic key of the automobile, or other terminal devices that have a requirement for improving the access security level.

Specifically, the second terminal device may record transmission time information for transmitting the second authentication information when transmitting the second authentication information, and actively transmit the transmission time information to the first terminal device, or transmit the transmission time information according to a request of the first terminal device. When the second terminal device transmits the transmission time information of the second authentication information, the second terminal device may transmit the transmission time information together with the second authentication information, or may transmit the second authentication information and the transmission time information to the first terminal device, respectively. In the embodiment of the present invention, the first terminal device and the second terminal device may both perform time-based calibration or may perform real-time calibration via networking periodically or aperiodically.
In the embodiment of the present invention, the accessed device may also further verify the access device after receiving the access request sent by the access device, and perform the operation requested by the access device for the access after the verification passes.
Specifically, in some embodiments of the present invention, before receiving the second verification information from the second terminal device in S101, the method may further include: and transmitting the first authentication information to the second terminal device, wherein the second authentication information is generated in response to the first authentication information. Specifically, when the second terminal device wants to access the first terminal device, an access request may be sent to the first terminal device, where the access request may include device identification information of the second terminal device and other information required for device identity confirmation. After receiving the access request, the first terminal device may generate first authentication information, which may be, for example, a random number or a character string encrypted by an agreed key, and send the first authentication information to the second terminal device. After receiving the first verification information, the second terminal device may generate second verification information in response to the first verification information, for example, when the first verification information is a random number, the second verification information may be encryption information generated after encrypting the random number using a contract key, for example, when the first verification information is an encryption string, the second verification information may be an original string obtained by decrypting the encryption string using the contract key. And after the second verification information is generated, the second terminal equipment sends the second verification information to the first terminal equipment. The first terminal equipment verifies the second verification information, obtains a first time length between the second verification information is sent to the second terminal equipment and received, compares the first time length with a preset time length, and determines whether the second terminal equipment is allowed to access the first terminal equipment according to a comparison result.
By the embodiment of the invention, whether the access from the second terminal equipment is legal or not can be accurately judged when the first terminal equipment and the second terminal equipment carry out bidirectional authentication, so that illegal access can be effectively dealt with.

After receiving the access request, the first terminal device may generate first authentication information, which may be, for example, a random number or a character string encrypted by an agreed key, and send the first authentication information to the second terminal device. After receiving the first verification information, the second terminal device may generate second verification information in response to the first verification information, for example, when the first verification information is a random number, the second verification information may be encryption information generated after encrypting the random number using a contract key, for example, when the first verification information is an encryption string, the second verification information may be an original string obtained by decrypting the encryption string using the contract key. And after the second verification information is generated, the second terminal equipment sends the second verification information to the first terminal equipment. The first terminal equipment verifies the second verification information, obtains a first time length from the time of sending the first verification information to the time of receiving the second verification information from the second terminal equipment, and compares the first time length with a preset time length.
Here, the predetermined time period is determined in advance according to a time period required from when the first terminal device (or another device identical to the first terminal device) transmits the first authentication information to the second terminal device to when the first terminal device receives the second authentication information from the second terminal device in response to the first authentication information, which is measured when the first terminal device (or another device identical to the first terminal device) and the second terminal device (or another device identical to the second terminal device) are in direct communication connection, that is, the predetermined time period in the embodiment of the present invention corresponds to a reasonable time period required for information bidirectional transfer and information processing (including processing of analyzing the first authentication information and generating the second authentication information) by the second terminal device when the first terminal device and the second terminal device are in direct communication connection. Alternatively, a reasonable error range may also be considered when setting the predetermined time.
