The current paper proposes a solution for offloading compute-intensive string matching operations performed by modern network intrusion detection systems (NIDS) or ant viruses to the GPU using OpenCL's programing model and serialized implementations of Aho-Corasick algorithm. The solution aims to provide scalability and performance in heterogeneous(More)
ChaCha20 is an encryption cipher selected by Google to replace the now obsolete RC4 in the Chrome browser and Android devices. The current article discusses the performance implications of parallelizing ChaCha20 across multicore CPU and GPU. The serial implementation used to derive the parallel code is part of BoringSSL encryption library. We used OpenMP(More)
Network engineers and security experts are constantly confronted with new threats that have yet to be handled. Mitigation of zero day attacks requires the implementation of machine learning algorithms for the detection of abnormalities and malicious behavior on the network. These processes are often time consuming and can add significant resource cost in(More)
