“…As a consequence of the extremely distributed nature of ubiquitous calculating, it is important to expand safety mechanisms that lend themselves well to the slight properties of smart ubiquitous calculating environments. In this paper J Al-Muhtadi et al [25] introduce a context-aware access control mechanism that employs threshold cryptography and multilayer encryption to offer a dynamic and really dispersed method for access control. They…”

Security Mechanism based on Threshold cryptography that are been implemented for Mobile Ad-hoc Network normally have its own disadvantages or limits. As there should be at least the minimum number of nodes as per been declared in the threshold value to make the system running but there not always the number of nodes according to the threshold value so there is always a chance that system does not work even there is just a single node less than the threshold and even the system is not been compromised that problem can be solved using extended threshold cryptography(XTC). This paper concentrates how to provide a more secure mechanism in MANET using XTC.

“…Context-aware access control merges data from multiple context sensors and uses this data to determine whether users should be given access to context restricted resources. Encryption is used to restrict access to data resources [22]. The idea of encrypting sensitive data is done based on the confidential or secret levels such as SECRET and TOP SECRET.…”

The rapid growth of mobile telecommunications industry has been influencing the tremendous technological diffusion offering lower access cost, mobility, and convenience based communication as compared to wired telecom. The global rise of mobile competition helped service providers to offer much improved services both in terms of capabilities, information processing, retrieval, and communication over typical problems of inefficiencies generated by monopolies in wired networks. While there are significant opportunities to leverage the growth of mobile devices to increase the effectiveness of mobile users, also there are significant concerns about security and privacy of sensitive data that must be handled in these devices. Correspondingly, cyber security is becoming one of the top priorities for any nation. This paper reviews and presents some of the literature exercises in this regard. Objectives of this paper are: (i) to bring into light the explicit and implicit assumptions on the nature of technological change and how they could raise security issues, (ii) to discuss the technology and management perspectives on the security issues, and (iii) to present them through a methodology oriented taxonomy. It is believed that the adoption of methodology driven by sense-and-respond model would serve as an effective means to achieve these objectives.

“…To recover the secret a pre-specified number of parties must collaborate in order to obtain the secret. A threshold scheme of ( , ) means that a secret is divided among parties however any parties out of the parties can jointly obtain the secret [4]. The private key of the service is divided into shares ( 1, 2, .…”

Abstract. This chapter presents a secure mHealth application which is based on hybrid cloud architecture combined with cryptographic techniques to protect data privacy, integrity and security of patients and health care givers and with role based access control to authenticate and authorize cloud users. Hybrid cloud platform combines the advantages of both the private cloud which guarantees privacy and safety of data and the public cloud which provides a platform for reduced services costs. Integrating cryptography and role based access control with hybrid cloud computing ensures the safety of patients' medical records and enables user authentication and authorization for access control. This integrated technology can provide mHealth care the required safety and privacy to flourish.
