  • Generating a Symmetric Key to Secure a Communication Link
    Publication number: 20140237246
    Abstract: A symmetric key to be used to secure a communication link between a first device and a second device is generated as follows: a first symmetric key is generated; a second symmetric key is generated; packets communicated between the first device and the second device over communication link are hashed to create a hash result; the first symmetric key, the second symmetric key and the hash result are hashed to generate a third symmetric key to be used to secure the communication link.

  • SYSTEMS, DEVICES, AND METHODS FOR DISPLAYING A BARCODE AT A COMPUTING DEVICE
    Publication number: 20140224890
    Abstract: Embodiments of the systems, devices, and methods described herein generally facilitate the display of a barcode at a computing device for capture by another computing device. In accordance with one example embodiment, a barcode is generated at a first computing device, the barcode is displayed on a display screen associated with the first computing device, and one or more display properties of the barcode are dynamically modified while it is displayed at the first computing device until the barcode is successfully captured (e.g. by a camera) at a second computing device.

  • Protocol for protecting content protection data
    Patent number: 8792636
    Abstract: Through the use of a one-time-use nonce, the transfer of cryptographic data over a potentially insecure link in a two-factor content protection system is avoided. The nonce may be stored encrypted with a public key from a smart card. A random key may be used to produce a storage key, which is used to encrypt a content protection key. The random key may be stored, encrypted with a key derived from the nonce. Instead of receiving a raw content protection key over the potentially insecure link, the raw nonce is received and, once used, replaced with a new nonce.

  • System and method for retrieving certificates associated with senders of digitally signed messages
    Patent number: 8788812
    Abstract: A system and method for retrieving certificates and/or verifying the revocation status of certificates. In one embodiment, when a user opens a digitally signed message, a certificate that is required to verify the digital signature on the message may be automatically retrieved if it is not stored on the user's computing device (e.g. a mobile device), eliminating the need for users to initiate the task manually. Verification of the digital signature may also be automatically performed by the application after the certificate is retrieved. Verification of the revocation status of a certificate may also be automatically performed if it is determined that the time that has elapsed since the status was last updated exceeds a pre-specified limit.

  • INCORPORATING DATA INTO AN ECDSA SIGNATURE COMPONENT
    Publication number: 20140201535
    Abstract: During generation of a signature on a message to create a signed message, a signer determines one of the signature components such that particular information can be extracted from the signature component. The particular information may be related to one or more of the signer and the message to be signed. After receiving a signed message purported to be signed by the signer, a verifier can extract the particular information from the signature component.

  • SYSTEM AND METHOD OF MOBILE LIGHTWEIGHT CRYPTOGRAPHIC DIRECTORY ACCESS
    Publication number: 20140173277
    Abstract: A system for handling an LDAP service request to an LDAP server for an LDAP service comprises a client program executable on a client system and a handler program executable on a handler system. The client program is operable to generate LDAP service request data corresponding to the LDAP service and provide the LDAP service request data for transmission from the client system, and further operable to receive LDAP service reply data in response to the LDAP service request data. The handler program is operable to receive the LDAP service request data transmitted from the client system and execute the LDAP service request to the LDAP server, receive LDAP service reply data from the LDAP server during one or more passes, and upon completion of the LDAP service, provide the LDAP service reply data for transmission to the client system in a single pass.

  • Method and system for determining support for a memory card
    Patent number: 8746562
    Abstract: Embodiments related to methods and systems for determining support for a memory card, where the memory card is accessible to a card reader and the card reader is in communication with an accessing device. One embodiment comprises transmitting a first test command to the memory card, receiving a response to the first test command, and determining that the response to the first test command indicates that a card type is not supported by a plurality of card drivers. In response to said determining, at least one additional test command specific to a card type supported by a selected card driver is automatically transmitted, and if the response is successful, the selected card driver, which was previously determined not to support the card type of the memory card, is indicated to support the card type of the memory card.

  • System and method for processing certificates located in a certificate search
    Patent number: 8719565
    Abstract: 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.
