Secure Outsourced Attribute-based Signatures Attribute-based signature (ABS) enables users to sign messages over attributes without revealing any information other than the fact that they have attested to the messages. However, heavy computational cost is required during signing in existing work of ABS, which grows linearly with the size of the predicate formula. As a result, this presents […]
Scalable Distributed Service Integrity Attestation for Software-as- a-Service Clouds Software-as-a-service (SaaS) cloud systems enable application service providers to deliver their applications via massive cloud computing infrastructures. However, due to their sharing nature, SaaSclouds are vulnerable to malicious attacks. In this paper, we present IntTest, a scalable and effectiveservice integrity attestation framework for SaaS clouds. IntTest provides a novel integrated attestationgraph analysis scheme that can provide stronger attacker pinpointing power than […]
