Two most important goals of server assisted signature schemes are to aid small and mobile devices in computing digital signatures and to provide immediate revocation of signing capabilities. In this paper, we introduce an efficient scheme named server assisted one-time signature (SAOTS) alternative to server assisted signature scheme introduced by Asokan et al. Extended the Lamport's one-time signatures by utilizing hash chains, this new scheme's advantages are two-folds; first of all, it is communication-efficient running in fewer rounds, two instead of three, secondly, verification of server's signature can also be performed off-line resulting in real-time efficiency in computation as well as flexibility in the public-key signature scheme to be used. The experiments we have conducted showed that at least 40% gain in performance is obtained if SAOTS is preferred.

EPICS: A Framework for Enforcing Security Policies in Composite Web Services Ranchal, Rohit; Bhargava, Bharat; Angın, Pelin; ben Othmane, Lotfi (Institute of Electrical and Electronics Engineers (IEEE), 2019-05-01) With advances in cloud computing and the emergence of service marketplaces, the popularity of composite services marks a paradigm shift from single-domain monolithic systems to cross-domain distributed services, which raises important privacy and security concerns. Access control becomes a challenge in such systems because authentication, authorization and data disclosure may take place across endpoints that are not known to clients. The clients lack options for specifying policies to control the sharing of...
Slide attack and its applications Uslu, Erkan; Doğanaksoy, Ali; Uğuz, Muhiddin; Department of Cryptography (2017) Block ciphers, widely used in cryptography, have been designed to encrypt large amount of data such as public sector services, banking services, Healthcare contributions. With the increment of technological developments, they have also been started to be used for small data in industrial products such as Internet of Things, smart cards, car keys etc. These types of cryptosystems are called as lightweight cryptosystems. Similar to other cryptographic algorithms, the ones used in lightweight systems need to b...
PLGAKD: A PUF-based Lightweight Group Authentication and Key Distribution Protocol Yıldız, Hüsnü; Cenk, Murat; Onur, Ertan (Institute of Electrical and Electronics Engineers (IEEE), 2020-11-01) Securing Internet of Things (IoT) applications that collect and transport sensitive data by guaranteeing authenticity, integrity, and confidentiality is a critical challenge. Reducing computation and communication overhead of security functions is also a key concern since a large number of constrained devices may take place in such applications. Our main focus in this paper is group authentication and key management in IoT. The existing group authentication and key management protocols in the literature per...
On-demand conversation customization for services in large smart environments Elgedawy, I. (IBM, 2011-01-01) Services in large smart environments, as defined in this paper, are "aware" of their users' contexts and goals and are able to automatically interact with one another in order to achieve these goals. Unfortunately, interactions between services (i.e., service conversations) are not necessarily compatible, as services could have different interfaces (i.e., signature incompatibilities), as well as different logic for message ordering (i.e., protocol incompatibilities). Such conversation incompatibilities crea...
SIMULATION CONCEPTS FOR INFORMATION-SYSTEM MOURANT, RR; Tarı, Zehra Sibel (Elsevier BV, 1993-09-01) Recent Improvements in document image systems and their low-cost implementation on networks of microcomputers is leading to the reengineering of many information systems. We describe how document image systems can be applied to information systems. In order to compare the performance of a conventional information system with one implemented with document imaging processing capability we conducted a discrete event simulation. We modeled the conventional information system for processing graduate student ...
