Security Techniques in Cloud Computing for Cloud Data Storage

Cloud and Internet of things application are growing day by day. Most of the organization are using the cloud storage services for own application. IOT application are building under the 5G wireless communication technologies. Security is the major concern for data security and safety. The basic techniques start from using the watermarking with advancement of the cryptography algorithm. Most of the online and cloud application are using the cryptography-based data security. The most common and high secure cryptography algorithms are AES, RSA, Hash etc. This paper presents the cryptography techniques and challenges for the security in cloud data storage for IOT applications.
