Telemedicine started its journey and successful deployment over several decades. But still it could not mark a remarkable contribution to neither rural nor urban areas. People realized its impact when it saved a life from becoming an extinct. Telemedicine connects patient and specialized doctors remotely and also allows them to share the sensitive medical records. Irrespective of the mode of data exchange, all types of media are vulnerable to security and performance issues. Remote data exchange during an emergency situation should not be delayed and at the same time should not be altered. While transit, a single bit change could be interpreted differently at the other end. Hence telemedicine comes with all the challenges of performance and security issues. Delay, cost and scalability are the pressing performance factors whereas integrity, availability and accountability are the security issues need to be addressed. This paper lights up on security without compromising quality of service. Telemedicine is on track from standard PSTN, wireless Mobile phones and satellites. Secure Cloud based Telemedicine (SCT) uses Cloud which could free the people from administrative and accounting burdens. © 2014 IEEE.

SCT: Secured Cloud based Telemedicine

The 2014 International Symposium on Networks, Computers and Communications

Exceptional characteristics of cloud computing have replaced all traditional computing. With reduced resource management and without advance investment, it has been victorious in making the IT world to migrate towards it. Microsoft announced its office package as Cloud, which can prevent people moving from Windows to Linux. As this drift is escalating in an exponential rate, the cloud environment has also become a target for attackers. Hence to acquire the best use of the cloud services, the security issues have to be dealt with first. Among various security threats faced by the cloud environment, this paper focuses on the most dangerous one, Distributed Denial of Service attack, DDoS. In DDoS attack, a victim is targeted simultaneously by numerous hosts distributed across the network. An attacker compromises the vulnerable systems in the network and infects those systems with malicious code which can trigger these systems, called zombies, to send requests in huge numbers to choke the target. This type of attack can happen both at network as well as service level. Network level attack is achieved by sending simultaneous invalid or incomplete requests, whereas in service level attacks, the target will be flooded with complete request for services provided by the CSP, but with malicious intent. These two types of attack trafficshave to be filtered out at different levels. In this paper, a three phase authentication scheme, REputation based Service for Cloud User Environment (RESCUE) has been proposed that can help the cloud service provider to detect and mitigate both the aforesaid types of DDoS attacks. RESCUE, the proposed scheme authenticates the users in three different phases. The simulation results presented here exhibits the strength of the proposed method in detection and prevention of DDoS attack in cloud computing environment.

Reputation Based Service for Cloud User Environment

AbstractAvailability is one of the primary security issues in Cloud computing environment. The existing solutions that address the availability related issues can be applied in cloud computing environment, but because of their unique characteristics, such as on-demand self service, rapid elasticity, etc., there is a need to develop a detection mechanism that must satisfy the characteristics and an optimal profit for the Cloud Service Provider (CSP). A solution named Escape-on- Sight (EoS) algorithm is proposed in this paper that helps in detecting the attacker’s characteristics by analyzing traffic conditions stage by stage and protects the Data Center (DC) from malicious traffic. The profit analysis shows that the proposed approach has a reasonable chance of deploying EoS mechanism at DCs that are prone to DDoS attacks.
