Security issues and Cryptographic techniques in Cloud Computing

Abstract

Cloud computing is an emerging paradigm that provides cheap, on demand resources and services over a network. It has become primary distributed computing platform. It eliminates the need of maintaining costly computing facilities by companies and institutes. One of the barriers for cloud adoption is security. There are no proper laws which govern who own responsibility as data flows across cloud.

This article gives a quick introduction to cloud computing. Then it covers various threats and security issues in today’s cloud and cryptographic ways for maintaining security in cloud.

Keywords: cloud computing, security threat, multi-tenant behavior, cryptographic techniques, standards and policies
