Since communication among VMs on the same physical machine is done through emulation, it does not use any network bandwidth. Therefore, placement of virtual clusters should utilise this fact to reduce unnecessary bandwidth consumption. To achieve this goal, one has to consider the constraints of the physical machines, as well as the communication relationship among the virtual machines of the virtual cluster. In this paper, we propose to use a monitoring/profiling mechanism to track and to classify virtual clusters. The information is then used by a resource provisioning mechanism to place virtual machines on physical machines, such that unnecessary network bandwidth consumption is reduced. Our experimental results show that, the proposed mechanism significantly outperforms the default VM scheduler provided by OpenStack.","PeriodicalId":171228,"journal":{"name":"Int. J. Serv. Technol.

Managed codes can be easily modified; therefore many static prevention techniques are applied. However, static prevention techniques can be immobilised by dynamic reverse engineering tools. Reverse engineering tools for such managed code operate using QEMU-based emulator methods. Among the many anti-reversing techniques to detect tampering of the application, schemes that terminate the application when an emulator has been detected are being used. In this paper, we compare and analyse the characteristics of the various schemes used to detect emulator-based reverse engineering tools and report experimental results on the effectiveness of the methods in question.","PeriodicalId":171228,"journal":{"name":"Int.

It authenticates users and devices whether they are trusted or not and it controls the access of the devices according to their security state. As the age of internet of things and bring your own device has begun, NAC technique has become more important. However, it is hard to adopt the NAC from small and medium sized enterprise because of the cost problem. For this reason, we suggest lightweight NAC on wireless router. To do this, we developed an advanced NAC module added to OpenWrt, open source wireless router firmware, which allows to establish secure network environment without additional NAC appliance. We also developed agent programs for PC and mobile to examine the security state of device and identify the trusted users and devices.","PeriodicalId":171228,"journal":{"name":"Int. J. Serv. Technol.

The security of a cryptographic scheme can be achieved under the assumption that the system uses ideal random numbers to produce sensitive security parameters such as encryption keys and initial vectors. The weakness of the random number generator makes the entire cryptographic system insecure. In particular, the lack of entropy sources leads to predictable output random bits so that secret information can be guessed by malicious attackers. Therefore, it is important to collect sufficient entropy from physical noise sources. In this paper, we consider graphics processing units (GPUs) as an entropy source. From the race conditions in the parallel computations on a GPU, we can harvest sufficient entropy for cryptography. Using the entropy estimations in NIST SP 800-90B, the amount of entropy is estimated and compared with other physical sources.","PeriodicalId":171228,"journal":{"name":"Int. J. Serv. Technol.

These challenges can be efficiently addressed using novel data signing schemes. We compare personal digital signature solutions provided by public key infrastructure (PKI) and keyless signature infrastructure (KSI) and describe how these technologies can support each other. We discuss some ways of integrating a personal KSI service with external identity providers. As KSI can 'indemnify' PKI against the cryptographic threat of practical quantum computers, we delve into the post-quantum security of cryptographic hash functions and hash-and-publish signature schemes.","PeriodicalId":171228,"journal":{"name":"Int.

Due to significant advances in sensor and RFID technologies, smart devices are now connected via the internet and able to communicate with each other without human intervention. Hence, the amount of data collected about individuals has increased dramatically. The ability of machines and sensor devices to collect, transmit and share data has raised privacy concerns in IoT applications. Recently, privacy concerns about data collected by IoT applications have received an increasing amount of attention. Therefore, a series of security mechanisms must be available for data privacy protection. In this paper, we propose two secure correlation computation protocols for IoT applications. We concentrate on the asymmetric setting where only one party receives the computation result. We incorporate homomorphic cryptosystem into our computation to support operations in an encrypted form. Two experimental results in this paper demonstrate the performance of both computation protocols.","PeriodicalId":171228,"journal":{"name":"Int. J. Serv. Technol.

We researched and analysed vulnerabilities with Windows platforms and compared with the analysed result in terms of the difference in user privilege, Windows operating system and version of Internet Explorer. We found vulnerabilities that occurred only in specific Windows product or version of Internet Explorer.

Moreover, to implement various heating patterns, the constant voltage applied to the heater was adjusted using voltage regulator (VR).
