  • Patent number: 8838958
    Abstract: A method for using a network appliance to efficiently buffer and encrypt data for transmission includes: receiving, by an appliance via a connection, two or more SSL records comprising encrypted messages; decrypting the two or more messages; buffering, by the appliance, the two or more decrypted messages; determining, by the appliance, that a transmittal condition has been satisfied; encrypting, by the appliance in response to the determination, the first decrypted message and a portion of the second decrypted message to produce a third SSL record; and transmitting, by the appliance via a second connection, the third record. Corresponding systems are also described.

  • Patent number: 8793503
    Abstract: In a method for managing sequential access to secure content by a plurality of workflow participants, a key-map file for each of the participants is created. Each of the key-map files contains a subset of encryption and signature keys for the content. The key-map files are sorted in an order that is the reverse of a workflow order in which the workflow participants for which the key-map files were created are to access the secure content. An encrypted later wrap including a later key-map file for a later workflow participant along the workflow order and an encrypted first wrap including a prior key-map file for a prior workflow participant and the encrypted later wrap are created. In addition, the first wrap is incorporated into a document serialization for the content.

  • Patent number: 8789188
    Abstract: Systems and methods are presented for automatically determining the security requirements of program code during the creation or modification of that program code and for presenting the necessary security permissions to a developer of the program code at the time of the creation or modification of the program code. A cache is established containing program code segments including library calls and application program interfaces that require security permissions at runtime. The cache also includes the security permissions associated with the stored program code segments. Program code editing is monitored in real time during the editing, and instances of edits that add, modify or delete the stored program code segments from the program code being edited are identified. The security permissions associated with the program code segments that are modified by the edits are retrieved from the cache.

  • Patent number: 8767960
    Abstract: Information, such as audio visual information, is secured by self-decay of the information over time. For instance, a date stamp and decay rate embedded in an encrypted audio or visual digital media file can be applied to decrypt the file to a predetermined decayed state, such as a degraded playback quality. One or more keys can be included with the information to allow undecayed decryption but expire after use or a predetermined time period. In one embodiment, the decayed state can comprise gaps formed at intervals in the information, the gaps having increased length for decreased quality. In an alternative embodiment, the decayed state can be a reduced sample rate for a compressed digital media file.

  • Patent number: 8681976
    Abstract: Disclosed herein are systems, methods, and non-transitory computer-readable storage media for generating a device dependent cryptographic key in a rate-limited way. A system configured to practice the method first receives data associated with a user. The data associated with the user can be a password, a personal identification number (PIN), or a hash of the password. Then the system performs a first encryption operation on the user data based on a device-specific value to yield first intermediate data and performs a second encryption operation on the first intermediate data based on the device-specific value to yield second intermediate data. Then the system iteratively repeats the second encryption operation until a threshold is met, wherein each second encryption operation is performed on the second intermediate data from a previous second encryption operation. The iterations produce a final cryptographic key which the system can then output or use for a cryptographic operation.

  • Patent number: 8665943
    Abstract: The present invention relates to an encoding apparatus, an encoding method, an encoding program, a decoding apparatus, a decoding method and a decoding program for adaptively controlling an encoding bit rate. Coefficient data obtained using wavelet transform is quantized, and segmented into bit planes. The coefficient data is entropy encoded from the bit plane of the MSB in a direction from an upper bit position to a lower bit position. Entropy encoding is stopped at a bit position where an amount of code has reached a target amount. On the bit plane, the coefficient data is entropy encoded from a lower frequency region to a higher frequency region. Data greatly affecting subjective image quality of a decoded image is selectively output while the amount of code is easily controlled.

  • Patent number: 8640202
    Abstract: A mechanism is provided for synchronizing a first user session and a second user session in a client-server system. The first user session is between a first Web service and a client and the second user session is between a second Web service and the same client. A request is received with a first session value by the second Web service. An indicator of the first session value is assigned to a shadow, and the shadow is sent in a response to the client. A subsequent request with the shadow and a subsequent session value is received from the client. The indicator is used to verify the subsequent session value at the second Web service. The second user session is terminated if the indicator in the shadow does not correspond to the subsequent session value.
