Embodiment 2

[0112] This application also provides another method for unlocking and locking a mobile smart device and its corresponding bluetooth card, wherein the initialization includes the following steps:

[0113] Step P1: The mobile smart device initiates an initialization request, securely connects the Bluetooth smart card through Bluetooth pairing, and ensures that the Bluetooth communication link is encrypted and reliable;

[0114] Step P2: The Bluetooth smart card generates an asymmetric key in a secure environment, including but not limited to RAS public-private key pair;

[0115] Step P3: The Bluetooth smart card sends the public key to the mobile smart device;

[0116] Step P4: The mobile smart device generates a random encryption key, and encrypts it with the public key as the session key;

[0117] Step P5: The mobile smart device uses the private key to decrypt the session key, uses including but not limited to the 3DES algorithm to symmetrically encrypt the summary and stor...

Abstract

The application discloses a method for unlocking and locking mobile intelligent equipment by utilizing a Bluetooth intelligent card and a Bluetooth intelligent card. The method comprises the steps that: the Bluetooth intelligent card is close to the mobile intelligent equipment and determines whether a distance between the Bluetooth intelligent card and the mobile intelligent equipment is smallerthan a specified distance according to intensity of a received signal; if the distance between the Bluetooth intelligent card and the mobile intelligent equipment is smaller than the specified distance, the Bluetooth intelligent card generates an asymmetrical secret key in a safe environment and sends a public key to the mobile intelligent equipment; the Bluetooth intelligent card receives a random encrypted secret key which is transmitted by the mobile intelligent equipment and encrypted by the public key and the random encrypted secret key is used as a first session secret key; and the Bluetooth intelligent card decrypts the first session secret key by a private key, carries out encryption on unlocking information by the decrypted first session secret key, and transmits the decrypted unlocking information to the mobile intelligent equipment, so that the mobile intelligent equipment executes unlocking of a screen by utilizing the decrypted unlocking information. According to the application, as long as the mobile intelligent equipment is close to the Bluetooth intelligent card, unlocking and locking of the screen can be automatically implemented.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for unlocking and locking a mobile smart device and a bluetooth smart card. Background technique [0002] Mobile smart devices such as mobile phones and pads are devices that almost everyone in the modern information society has, which facilitates everyone's work and life and improves work efficiency. With the increasing degree of electronic informatization in modern society, a large amount of information is stored on mobile smart devices, and most of them are used in public places, how to protect the security of mobile smart devices has become very important. People generally use passwords, gesture patterns, etc. to lock mobile smart devices, but it is easy to be snooped by others, and the security of unlocking cannot be guaranteed. Contents of the invention [0003] The purpose of this application is to provide a method for locking and unlocking a mobile smart device with ...
