  • Patent number: 8005975
    Abstract: A new P2P streaming method and apparatus disseminates video chunks to all peers with the minimum (or at least reduced) delay. After obtaining a new video chunk, a peer keeps transmitting (uploading) that video chunk to other peers until all peers receive it. The approach quickly increases the aggregate bandwidth that can be utilized to transmit a video chunk. For example, the aggregate peer bandwidth used to transmit a video chunk can double every time slot. For a homogeneous P2P streaming system with N peers, a time slot is defined as a unit of the single chunk transmission delay between two peers. Using the P2P streaming method, a video chunk can be disseminated to all peers within 1+log2 N time slots.

  • Patent number: 7953988
    Abstract: An active membrane creates a secure area around one or more devices. The active membrane forms a physical barrier between the encased secure area and an external environment. Linked to the membrane and acting as the sole interface between the secure area and the outside environment is a boundary interface. The boundary interface tunnels data to the secure area in a secure fashion. According to one embodiment of the present invention, the boundary interface utilizes symmetric and/or asymmetric cryptographic techniques to secure the data path. The boundary interface is also coupled to the active membrane, and upon the membrane sensing a breach of the membrane (thus signifying an intrusion of the secure area), the boundary interface can be configured to sever the data paths linking the secure area with the unsecured area as well as take other active steps to ensure that data within the secure area is not compromised.
