“…To achieve the encryption process in the proposed schemes, computation of trace is needed. The arithmetic complexity of computing T r ( α ) is O ( c log m ) with c < 6 (the required number of multiplications) . The arithmetic complexity of encryption process for the scheme given in is O (9 log m ) by .…”

In this paper, we propose novel deterministic and probabilistic public key cryptographic schemes based on an effective and compact subgroup trace representation cryptosystem to handle with the problem of secure and efficient communication between the server and resource‐constrained device. The proposed schemes use the hardness of the Trace‐discrete logarithmic like problem. We also show that the deterministic version of the proposed scheme is a one‐way trapdoor, and the probabilistic version of the proposed scheme is semantically secure. Moreover, we discuss the efficiency of the proposed schemes by comparing with effective and compact subgroup schemes. Copyright © 2015 John Wiley & Sons, Ltd.

Abstract-Cloud computing is an extended environment of information technology services that offers unlimited computing services to improve productivity and operational efficiency. It supports resource sharing and multi-tenancy with reduced capital and operational expenditure. So nowadays, the private enterprises, government organizations, educational institutional are adopting cloud services for their work. As ease of use and low-cost benefits are two main features of cloud computing, security and trust are two main issues related to cloud services. In recent years, a lot of research on cloud security has been carried out and many more techniques and methods are proposed to overcome cloud security issues. One such security measure we are focusing here is user authentication. This paper identifies different authentication attacks and techniques approached to improve authentication in Cloud.
