There is a signature scheme which can aggregate two or more persons' signatures to one, called an aggregate signature. ...
In this paper, we propose a scheme of an aggregate signature which has additional functionality allowing any holder of a signature to designate the signature to any desired designated-verifier. ...
The Model of Universal Designated-Verifier Signature with Aggregation First, we introduce an aggregate signature. Consider a set U of users. Each user U i ∈ U has a signing key pair (sk i , pk i ). ...

In terms of both computation time and space, materializing a universal base table by joining multiple tables is often very expensive or even unaffordable in real data warehouses. ...
Surprisingly, our study shows that computing iceberg cube from multiple tables directly can be even more efficient in both space and runtime than computing from a materialized universal base table. ...
Thus, for any local iceberg cell c in P D 2 whose signature contains e 1 or e 2 , such as ( * , f 1 , * , * ), can be a global iceberg cell, if the overlap of the signatures can lead to an aggregate value ...
