    摘要: A system comprises a wireless-enabled device that communicates with a wireless-enabled smart card reader to obtain information from or perform operations using a smart card. Commands to access information from a smart card may be sent from the device to the smart card reader, and responses from the smart card may be sent from the smart card reader back to the second device. Communication between the device and the smart card reader via a wireless communication link is slower than communication via a direct link. Communication of two or more commands and/or responses via the wireless communication link may be made more efficient by grouping the commands or responses together in groups.

    摘要: An active new password entry dialog provides a compact visual indication of adherence to password policies. A visual indication of progress towards meeting all applicable password policies is included in the display and updated as new password characters are being entered. A visual hint associated with at least one applicable password policy that has not yet been satisfied is also included in the display. An ability to obtain more detailed comprehensive password policy information is also permitted upon user command (e.g., including an indication whether each password policy has yet been met or unmet). Preferably the displayed hint and associated applicable password policy not yet satisfied is randomly changed during entry of a new password (e.g., upon the entry of each new password character).

    摘要: A method for secure bidirectional communication between two systems is described. A first key pair and a second key pair are generated, the latter including a second public key that is generated based upon a shared secret. First and second public keys are sent to a second system, and third and fourth public keys are received from the second system. The fourth public key is generated based upon the shared secret. A master key for encrypting messages is calculated based upon a first private key, a second private key, the third public key and the fourth public key. For re-keying, a new second key pair having a new second public key and a new second private key is generated, and a new fourth public key is received. A new master key is calculated using elliptic curve calculations using the new second private key and the new fourth public key.

    摘要: Authentication of two devices in communication with a third device is achieved where the first and second devices each possess a shared secret value. The authentication includes communication of authentication values from the first device to the second device using the third device. Similarly, there is communication of values from the second device to the first device using the third device. The third device retains the communicated values. The values are calculated to permit the third device to authenticate the first and second devices without the third device receiving the shared secret value. The authentication may be used to establish a communications channel between the first and the second devices.

    摘要: A system and method for processing certificates located in a certificate search. Certificates located in a certificate search are processed at a data server (e.g. a mobile data server) coupled to a computing device (e.g. a mobile device) to determine status data that can be used to indicate the status of those certificates to a user of the computing device, without having to download those certificates to the computing device in their entirety. The data server is further adapted to transmit the status data to the computing device. In one embodiment, at least one status property of the certificates is verified at the data server in determining the status data. In another embodiment, additional certificate data is determined and transmitted to the computing device, which can be used by the computing device to verify, at the computing device, at least one other status property of the certificates.

    摘要: A system and method for associating message addresses with certificates, in which one or more secondary message addresses are identified and associated with a user-selected certificate. The secondary message addresses are saved in a data structure that resides in a secure data store on a computing device, such as a mobile device. When a message is to be encrypted and sent to an individual using a particular certificate, an address mismatch would not be detected so long as the address to which the message is to be sent matches any of the message addresses associated with the certificate. The message addresses associated with the certificate include any message addresses contained within the certificate itself (“primary message addresses”) as well as any secondary message addresses that have been subsequently associated with the certificate.
