摘要： An apparatus and method for storing security information are provided. The apparatus is generally an electronic device that includes a memory configured to include a secured region to store security information and a processor configured to electrically connect with the memory. The processor is further configured to execute an application program configured to store the security information in a first secured region, to receive a request to store the security information from the application program, and to store the security information in a second secured region different from the first secured region in response to the request.

摘要： A method for providing an anti-rollback secure timer service includes determining, at a device which includes a processor providing a trusted execution environment (TEE), a trusted memory, and a real time clock (RTC) accessible through an operating system of the device, an initial reference time value, by a secure timer application running in the TEE, the initial reference time value determined based on an initial value of the RTC obtained during booting of the device and a time delta value. The method further includes determining an updated reference time value based on the initial reference time value, a second value of the RTC, and a previously stored old reference time value, determining an updated time delta value based on the second value of the RTC and the updated reference time value, and storing the updated time delta value and the updated reference time value in the trusted memory.

摘要： A method includes receiving a challenge from an authentication consumer. The method also includes generating for display a figure associated with an identification, a public certificate, and a private key after receiving the challenge. The figure, the identification, the public certificate, and the private key are stored in a TrustZone (TZ) enriched environment. The method further includes receiving an input identification. The method includes verifying that the input identification matches the identification. The method also includes transmitting the challenge to the authentication consumer in response to verifying that the input identification matches the identification.

摘要： A method, electronic device, and non-transitory computer readable medium for transmitting information is provided. The method includes creating a card network account for each card network of a plurality of card networks. The method also includes associating with a digital card the created card network accounts and providing to at least one of the card network accounts an account balance of the digital card. Additionally, the method includes receiving, from a mobile device, a selection of the digital card to conduct a transaction at a location. The method also includes providing a suggested card network, determined from the plurality of card networks, to the mobile device, to conduct the transaction. The suggested card network is based in part on which card networks accepted at the location. The method also includes updating the account balance of the digital card on completion of the transaction.

摘要： An apparatus and a method for encrypting and decrypting data in a device are provided. The apparatus includes a processor and a memory. The processor is configured to transmit a data command from an application to an encryption driver that executes in a kernel space, determine if the application is authenticated to perform the data command based on an access policy, transmit, when the application is authenticated, a first key to a cryptographic library that executes in an application space, and perform the data command based on the first key after receiving a response via the cryptographic library. The first key is stored in an encryption driver in the kernel space and is not available to applications in the application space.
