Universal forgery of the identity-based sequential aggregate signature scheme

Jung Yeon Hwang, Dong Hoon Lee, Moti Yung
2009 Proceedings of the 4th International Symposium on Information, Computer, and Communications Security - ASIACCS '09  
In the paper, unfortunately, we show that the scheme is universally forgeable, i.e., anyone can generate forged signatures on any messages of its choice.  ...  At CCS'07, a novel identity-based sequential aggregate signature scheme was proposed and the security of the scheme was proven under the hardness assumption of a new computational problem called modified  ...  An identity-based sequential aggregate signature(IBSAS) scheme provides the functionality of a sequential aggregate signature only using a signer identity such as an IP address as a public key.  ...

Universal Designated-Verifier Signature with Aggregation

A. Mihara, K. Tanaka
Third International Conference on Information Technology and Applications (ICITA'05)  
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 ).  ...

Cross Table Cubing: Mining Iceberg Cubes from Data Warehouses [chapter]

Moonjung Cho, Jian Pei, David W. Cheung
2005 Proceedings of the 2005 SIAM International Conference on Data Mining  
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  ...
