This dynamic data structure enables the efficient insertion and deletion of an interval in O (log n). Because intervals in the tree cannot overlap, the query time is also O (log n). When a new data segment is received, the stream fuzzy hash algorithm finds the segment context by querying...
In this work, we study variants of the above hashing approach to go beyond the birthday attack barrier. At a high-level, our approach, which can be traced back to Siegel [53], is based on applying a dictionary data structure,Footnote1in which the locations accessed in the search of an ...
