    摘要： In a system and method for authenticating a client device by an authentication device, the client device user is assigned a PIN generated by the authentication device. The user provides the PIN and a password to the client device, from which the client device generates a symmetric key and further generates a public/private key pair. The private key is encrypted using the symmetric key and stored in encrypted form only. The public key and a message authentication code generated from the PIN are provided to the authentication device, which stores the public key. Subsequently, when the user seeks to be authenticated, the user enters a password at the client device, which is used to generate a symmetric key to decrypt the encrypted private key. A message to the authentication device is signed using the resultant value. The authentication device uses the public key to verify the signature of the message.

    摘要： Systems and methods of owner application control of an electronic device are provided. Owner application control information is stored on the electronic device and/or one or more remote servers. Owner application control information is consulted to determine if one or more required applications are available for execution on the electronic device. If not, one or more required applications not available are downloaded and installed. This could be in a manner transparent to the user of the electronic device. If one or more required applications are not available on the electronic device, the device can be functionally disabled in whole, or in part, until one or more required applications are available.

    摘要： A system and method for providing an indication of randomness quality of random number data generated by a random data service. The random data service may provide random number data to one or more applications adapted to generate key pairs used in code signing applications, for example. In one aspect, the method comprises the steps of: retrieving random number data from the random data service; applying one or more randomness tests to the retrieved random number data to compute at least one indicator of the randomness quality of the random number data; associating the at least one indicator with at least one state represented by a color; and displaying the color associated with the at least one indicator to a user. The color may be displayed in a traffic light icon, for example.
