Network Intrusion Detection Systems (NIDSs) play a crucial role in detecting malicious activities within the networks. Basically, an NIDS monitors network flows and compares it with the pre-defined suspicious patterns. To be effective, different intrusion detection algorithms and packet capturing methods have been implemented. With rapidly increasing network speeds, NIDSs face a challenging problem...
In the Public Key infrastructure (PKI) model, digital certificates play a vital role in securing online communication. Communicating parties exchange and validate these certificates, the validation fails if a certificate has been revoked. In this paper we propose the Certificate Revocation Guard (CRG) to efficiently check certificate revocation while minimising bandwidth, latency and storage overheads...
Vision-based ego-motion estimation is a widely used method for identifying movements and poses of robots or equipped vehicles utilizing one or more attached cameras. This paper proposes a feature-matching-based method for estimating ego-motion using a calibrated two-camera stereo system. Detected features are separated into two candidate sets. Distant features are selected to provide information,...
