Abstract

People are using lot of cloud storage service (CSs) to store documents. The cloud storage
services are used to conserve people personal data and facilitate data transferable. The
computer which connected via internet is adequate to access the data anywhere without
carrying any physical drives like Pen drive, CD, etc. In existing techniques like, CSs providers
are using 256-bit Advanced Encryption Standard (AES) and 128-bit (AES) encryption
algorithm. This is one of the best techniques to secure data, but once the intruder gets
encrypted data, there is possibility for data insecurity by means of applying brute force
attacking technique in future increasing the speed performance of computer. The objective of
this paper to analysis cryptographic algorithm which perfume on various data formats and
data security attacks and threads in cloud storage environment. The aim to overcome this kind
of attacks and key tampering technique, the key generation and maintain process handover to
user’s itself. It makes cloud storage service provider to maintain data only, with high efficientencryption technique that provides strong protection for data.
