摘要： A system (126-129) detects transmission of potentially malicious packets. The system (126-129) receives packets and generates hash values corresponding to each of the packets. The system (126-129) may then compare the generated hash values to hash values corresponding to prior packets. The system (126-129) determines that one of the packets is a potentially malicious packet when the generated hash value corresponding to the one packet matches one of the hash values corresponding to one of the prior packets and the one prior packet was received within a predetermined amount of time of the one packet. The system (126-129) may also facilitate the tracing of the path taken by a potentially malicious packet. In this case, the system (126-129) may receive a message that identifies a potentially malicious packet, generate hash values from the potentially malicious packet, and determine whether one or more of the generated hash values match hash values corresponding to previously-received packets. The system (126-129) may then identify the potentially malicious packet as one of the previously-received packets when one or more of the generated hash values match the hash value corresponding to the one previously-received packet.

摘要： A system and method for identifying target packets in a network. The invention identifies packets by computing a hash value over at least a portion of a packet passing through a network device such as a router. The hash value is used as an address, or index, into a memory. The hash value identifies a unique memory address and a flag is set at the respective memory location. When a target packet is detected elsewhere in a network, the network device receives a query message containing a hash value of the target packet. The network device compares the target packet to the hash values in memory. A match between the hash value in memory and the hash value in the query message indicates the target packet was observed by the network device. After a match is detected, the network device makes a reply available to the network.
摘要翻译：一种用于识别网络中的目标分组的系统和方法。本发明通过在通过诸如路由器的网络设备的分组的至少一部分上计算散列值来识别分组。哈希值用作内存中的地址或索引。哈希值标识唯一的存储器地址，并且在相应的存储器位置设置标志。当在网络中的其他地方检测到目标分组时，网络设备接收到包含目标分组的哈希值的查询消息。网络设备将目标分组与存储器中的散列值进行比较。存储器中的哈希值和查询消息中的哈希值之间的匹配表示网络设备观察到目标分组。在检测到匹配后，网络设备向网络发出回复。

摘要： Shockwave-only solutions that estimate shooter position and shot trajectory are extremely sensitive to the quality and precision of the shock time-of-arrival (TOA) measurements as well as the accuracy to which relative sensor positions in space are known. Over the life of a long-deployed system, the sensor positions can shift and the performance of some sensors may degrade for various reasons. Such changes can degrade the performance of deployed shooter estimation systems. Disclosed are systems and methods that can be used to calibrate sensor positions based on shock and muzzle measurements processed from a series of shots fired from a known location and in a known direction, as well as an approach for dynamically adapting shock-only shooter estimation algorithms to compensate for sensor degradation and/or loss.

摘要： Systems and methods for locating the shooter of supersonic projectiles based on shockwave-only measurements are described. Muzzle blast signals are neither sought nor required. The system uses at least five, preferably seven, acoustic sensors that are spaced apart at least 1 meter. The sensor signals are acquired with a time resolution in the order of microseconds and processed to find and disambiguate the shockwave arrival angle unit vector. Two different Time-Difference-Of-Arrival (TDOA) measurement techniques are described, with one technique using counters in each signal channel and the other technique using cross-correlation between signal channels. A genetic algorithm can be used to efficiently disambiguate the results.

摘要： A system (200) detects transmission of potentially malicious packets. The system (200) receives, or otherwise observes, packets and generates hash values based on variable-sized blocks of the packets. The system (200) then compares the generated hash values to hash values associated with prior packets. The system (200) determines that one of the received packets is a potentially malicious packet when one or more of the generated hash values associated with the received packet match one or more of the hash values associated with the prior packets.
