A MEDIATED CERTIFICATELESS ENCRYPTION SCHEME FOR SECURELY SHARING SENSITIVE INFORMATION IN PUBLIC CLOUDS

In this abstract, we propose a new mCL-PKE scheme. We present the formal security model and provide the security proof. Since our mCL-PKE scheme does not depend on the pairing-based operation, it reduces the computational overhead. Moreover, we introduce an extension of mCL-PKE scheme to efficiently encrypt data for multiple …

ENHANCING THE QOS SUPPORT CAPABILITY OF HYBRID NETWORKS USING QOS-ORIENTED DISTRIBUTED ROUTING PROTOCOL

The emergence and the envisioned future of real time and multimedia applications have stimulated the need of high Quality of Service (QoS) support in wireless and mobile networking environments. The QoS support reduces end-to-end transmission delay and enhances throughput to guarantee the seamless communication between mobile devices and wireless infrastructures. …

MCLPKE SCHEME WITHOUT USING PAIRING OPERATIONS FOR SECURE DATA SHARING IN PUBLIC CLOUDS

An advantage of using a public cloud for storage is that the provider is responsible for building and maintaining the storage infrastructure and its associated costs including power, cooling and server maintenance. We propose a mediated certificateless encryption scheme without pairing operations for securely sharing sensitive information in public clouds. …

TRUSTEE-BASED SOCIAL AUTHENTICATIONS SYSTEMS FOR SECURITY

In this abstract, we aim to provide systematic study about the security of trustee-based social authentications. To this end, we first propose a novel framework of attacks that are based on the observation that users’ security are correlated in trustee-based social authentications. In these attacks, an attacker initially obtains a …

HYBRID WIRELESS NETWORKS WITH QOD ROUTING PROTOCOL

In order to enhance the QoS support capability of hybrid wireless networks, in this abstract, we propose a QoS-Oriented Distributed routing protocol (QOD). Taking advantage of fewer transmission hops and any cast transmission features of the hybrid networks, QOD transforms the packet routing problem to a resource scheduling problem. QOD …

SECURITY OF TRUSTEE-BASED SOCIAL AUTHENTICATIONS AGAINST FOREST FIRE ATTACK

Trustee-based social authentication has attracted increasing attentions and has been shown to be a promising backup authentication mechanism      . Specifically, a user’s security in trustee-based social authentications relies on the security of his or her trustees; if all trustees of a user are already compromised, then the attacker can also …

CLOUD COMPUTING WITH SHARED AUTHORITY BASED PRIVACY-PRESERVING AUTHENTICATION PROTOCOL

In our model, privacy is accomplished by encrypting the data it can prevent the un authorized access. We are going to raise the privacy level of the data owner and the confidentiality of the data by providing access to users. Here we proposed the secured system and data owner can …

BROKER-LESS PUBLISH/SUBSCRIBE SYSTEMS WITH IDENTITY-BASED ENCRYPTION

In publish/subscribe (pub/sub) communication, Publishers inject information into the pub/sub system, and subscribers specify the events of interest by means of subscriptions. Published events are routed to their relevant subscribers, without the publishers knowing the relevant set of subscribers, or vice versa. This abstract presents a novel approach to provide …

SAPA PROTOCOL FOR CLOUD STORAGE

In this abstract, we propose a shared authority based privacy preserving authentication protocol (SAPA) for the cloud data storage, which realizes authentication and authorization without compromising a user’s private information. The main contributions are as follows. 1) Identify a new privacy challenge in cloud storage, and address a subtle privacy …
