A method for access control on an electronic device includes the step of generating, by an electronic device, a certificate signed by a keymaster, the electronic device running an operating system, the operating system capable of distinguishing between applications and application processes and providing an execution environment. The method also includes the steps of indicating, by the certificate, an access privilege for an approved accessor and receiving from an application, a request subject to the access privilege indicated by the certificate. The method further includes the steps of identifying the application from which the request subject to the access privilege was received and determining, using the certificate, whether the application is an approved accessor.

System and method for certificate authority for certifying accessors

A method and apparatus are provided for secure communication. The method includes binding an isolated environment, of a device, to a secure component. The secure component includes a secure application and data. The method also includes utilizing the isolated environment as an intermediary for communication of the data between the secure application and the device.

Trusted execution environment secure element communication

An apparatus and method for securing a personal identification number (PIN) on a mobile device are provided. The method may include receiving a request for the PIN from a secure element on the mobile device, instantiating a trusted user interface (TUI), collecting the PIN via the TUI, and securely transmitting the PIN from a trusted execution environment (TEE) associated with the TUI to a secure element (SE).

Trusted pin management

An apparatus and method for securing sensitive data on a mobile device are provided. The method includes receiving an encryption or decryption request for the sensitive data on the mobile device, forwarding a file access request for the sensitive data to a secure environment, instantiating a trusted user interface (TUI), collecting user input via the TUI, generating a key using the collected user input, and encrypting or decrypting the sensitive data on the mobile device.

Apparatus and method for trusted execution environment file protection

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.

System and method for trustzone attested authenticators

An apparatus and method for storing authentication information on an electronic device are provided. The method includes receiving, by the electronic device, a unique key and a certificate matching the unique key in a secure environment of the electronic device, storing the unique key and the certificate matching the unique key in a secure environment of the electronic device, and wherein at least one of the unique key and the certificate matching the unique key identifies the electronic device.
