An Efficient Data Analysis Framework for Online Security Processing

Algorithm 4

The Search operation of LCN-Index.

	Input: attribute/value pair
	use equation (2) to calculate Sid;
	use equation (3) to calculate IDl;
	if IDl! = NULL then
	foreach each level i from 0 to k do
	c = 2 ∗ sid ∗ L + IDl; //Compute global ID of
	current SIU;
	if list[c]! = NULL then
	output(list[c]);
	ID l/ = 2;
