摘要： An implementation method for an encrypted USB flash disk system. A virtual drive letter is bound to an device object and then mapped; driver software wafts for an operation of an operating system on the device object; the driver software determines, according to the operation of the operating system on different device objects, the type of a received instruction; if the received instruction is a reading instruction, the driver software maps a read address in a storage chip according to a first address in the reading instruction, reads data, and calls an encryption lock chip to decrypt the read data to obtain decrypted read data; and if the received instruction is a writing instruction, the driver software calls the encryption lock chip to encrypt data to be written to obtain encrypted write data, maps a write address in the storage chip according to a second address in the writing instruction, and writes the encrypted write data or refuses the operation. The present invention can encrypt and store data and decrypt and read data, thereby ensuring the safety of data reading and writing, and can also use the encrypted USB flash disk as an optical disk for data reading and writing.

摘要： A method for implementing low power consumption on standby for a Bluetooth security device. The method comprises: a security module is waked up by a Bluetooth module and configures a working mode as the state of self; a security module determines whether data from the Bluetooth module is received by a fifth preset time; if yes, then executes a corresponding operation on the basis of the received data to produce an operation result, returns the operation result to the Bluetooth module, configures a low power consumption standby mode as the state of self, and waits to be waked up by the Bluetooth module; and if not, then configures the low power consumption standby mode as the state of self, and waits to be waked up by the Bluetooth module. The Bluetooth security device disclosed comprises the security module and the Bluetooth module, where the security module comprises a first configuration module, a first receiving module, a first determining module, an execution module, a first transmitting module, a second configuration module, and a waiting module. The method and the Bluetooth security device in the present invention are of great power saving effects, and the standby time of the Bluetooth security device is extended.

摘要： A method for preventing a hardware wallet from being maliciously paired, comprising: a hardware wallet waiting to receive a connection request; when a connection request is received, determining whether a first terminal sending the connection request has been paired and connected; if so, waiting to receive an instruction of the first terminal; and when receiving a pairing transfer instruction sent by the first terminal, clearing terminal information stored in a whitelist of the hardware wallet. By means of the present technical solution, a hardware wallet can achieve pairing transfer only by means of the authorization of a previously paired terminal, thereby improving the security of the hardware wallet.

摘要： A working method for an IC card having a fingerprint recognition function, comprising: an IC card receiving and determining an instruction type from a terminal, and when determined that the received instruction is an application selection instruction, the IC card selecting an application and returning a response to the terminal; when determined that the received instruction is a processing option acquisition instruction, the IC card acquiring a user fingerprint information verification state according to the content of the instruction, and if verification is successful, returning to the terminal a processing option instruction response containing an application file locator list for which a personal identification number does not need to be verified; if verification fails, returning to the terminal a processing option instruction response containing an application file locator list for which a personal identification number must be verified; when determined that the received instruction is a record reading instruction, the IC card returning a record reading response to the terminal according to the record reading instruction, wherein the record reading response contains a method for verifying a card holder. Thus, the risk of a personal identification number being leaked is avoided, thus enhancing the security of a transaction, while also improving user experience.
