摘要： The method involves transmitting to receivers receiving a multicast a plurality of requests for feedback (3), each request including a probability parameter (P). Each terminal replies to this (or not) with a corresponding probability (4). One then counts the number (r) of replies to each request (5); determines, from the counts and parameters, estimates of the number of receivers (6); and filters the estimates (7). The method further includes repeatedly computing a new probability parameter to be included in a subsequent feedback request, by forecasting, from the counts and parameters, a upper bound for the number of receivers (9, 10, 11) and determining from this the new probability parameter (12) such that the risk that the number of replies exceeds a predefined threshold is kept below a predefined value.

摘要： Data collected by sensors (10, 30) is transmitted to data collection points (31, 61) over a network using an epidemic protocol in which data received by a relay (3) is forwarded to a randomly-selected group of further relays (4, 5, 6) unless the same data has been previously received by the relay (3) or the data is time-expired. Data received by a relay (3) from different sources (1, 2, 30) in the same time-frame is aggregated using a Bloom filter process so that in each time frame only a single Bloom filter message is transmitted by each relay.

摘要： A key distribution server maintains a tree of nodes. Members of a group who are allowed access to information are associated with respective leaf nodes of the tree. The information is encrypted with a key comprising a join key field and a leave field, and these are associated with the root node of the tree. The join key is updated each time a member joins the group and the leave field is updated each time a member leaves. Further respective leave keys are associated with the other nodes of the tree. The leave keys of the tree are related so that a member knowing the leave key of its node can work out the leave key of the root node and hence decrypt the information. The key distribution server transmits offset messages to the members to allow them so to calculate the root node leave key. The system of offset messages reduces the amount of communication required between the key distribution server and the group members.

摘要： A Denial of Service attack received at a network node from a packet data communications network is managed by tracing the path of predominantly malicious data packets arriving at the network node. The attack may be mitigated by selecting a router along the detected path and requesting the router to alter its handling of the data traffic. In one embodiment, the selected router installs a filter for data directed at the network node. In a different embodiment, the router alters a Quality of Service setting for the data directed at the network node. The network node may also request the router to mark all data being forwarded to it, to allow the network to characterize the data and determine to what extent it consists of malicious data.

摘要： An authentication method for linked data is provided, which does away with the conventional requirement for secure authentication of every item of data using public key encryption or Message Access Codes. A subscriber to an indexed event announcement channel can access a first item of information which contains pointers to other items of information in which the user might be interested. A hash value of the pointed-to information is also provided in addition to the pointers themselves. In order to provide for authentication of the pointed-to information, the user authenticates the first item of information using a secure heavyweight authentication technique, and then uses the hash values of the pointed-to information contained in the first item of information to authenticate the pointed-to information when the user accesses it.
