The fast retrieval in archival traffic data is essential for network security and forensic analysis. A bitmap index is a data structure enabling fast search over large data collections in a limited time, but the space consumption is always a problem. WAH, PLWAH and COMPAX are proposed for compressing bitmap indexes for less storage. In this paper, a new bitmap index encoding scheme, named MASC, is...
Archiving of Internet traffic is essential for analyzing network events in the field of network security. Currently, bitmap indexing is used to accelerate the indexing and search queries for archival traffic data. However, the generation of bitmap index needs large storage space, which makes bitmap index compression is a must-have function. In this paper, we propose a new bitmap index encoding algorithm...
