Abstract: A computer security system comprises at least one authorized node constructed and arranged to execute a consensus protocol for validating and verifying a blockchain transaction and to extract at least one of a signature or feature of a detected cyberattack for the blockchain transaction and mining the transaction to a blockchain network; at least one unauthorized node prohibited from executing the consensus protocol and from validating and verifying a blockchain transaction but authorized to retrieve the at least one of the signature or feature from the blockchain network; and a special-purpose processor of the blockchain network that facilitates a distribution of the at least one of signature or feature for cooperative intrusion detection between the at least one authorized node and the at least one unauthorized node.

Abstract: A malicious process detection system comprises a Virtual Machine Introspection (VMI) module that performs an introspection operation on at least one virtual machine; and an Intrusion Detection System (IDS) that communicates with the VW module to generate data that is analyzed by the IDS using a negative selection algorithm (NSA) and that identifies suspicious processes at the VM based on the analyzed data.

Abstract: A method for detecting intrusion is provided using a combination of two AIS algorithms: Negative Selection Algorithm (NSA) and Dendritic Cell Algorithm (DCA). The method includes the following steps, or some functional subset of these steps: periodic monitoring of a data processing system for anomalous behavior that may indicate the presence of an intruder or an undesirable software; using the NSA for the generation of a population of detectors that are used for detecting anomalies in the monitored system via a matching criterion; using the DCA (which runs in parallel to the NSA) to sample traffic and signals coming in or out of the data processing system; using an aggregation system to combine the individual decisions of the NSA and the DCA to form a single final decision.

Abstract: The present invention relates to an improved method of de-jittering MPEG-2 and MPEG-4 data that is transmitted over a network. First, a network system jitter associated with periodic reference data packets is estimated. Then, the estimated system jitter is used to adjust clock-stamped reference values in the data packets before they are provided to the PLL for clock synchronization. The invented de-jittering method improves the PLL's ability to synchronize the MPEG data and provides for a better quality playback.

Abstract: The present invention provides a method for selecting and routing data in an ad-hoc mobile wireless network having a plurality of Nodes including multiple sources and destinations. The method includes sending a forward control packet from a source to the destination via at least one intermediate Node at intervals of time, where the intermediate Node is randomly selected. Each of the intermediate Nodes store weights of the neighbor Nodes. When the forward control packets reach the destination Node, they are evaluated in accordance with one or more given parameters and send back as backward control packets storing the evaluation results. As each of the intermediate Nodes receive the backward control packets, the weights of the corresponding neighbor Nodes are modified based on the stored evaluation results. Similarly, as the backward control packets are received at the source Nodes and the weights of the corresponding neighbor Nodes are modified based on the stored evaluation results.
