摘要：Cloud computing is the technology of using a network of remote servers on the internet . It further
avoids the use of a local -server. Customer can use applications without installations and access their personal files at
any computer with internet access. Day to day usage of cloud has attracted attackers to break data security in the cloud
data storage system. Security of cloud data is ensured by means of cryptographic keys which when exposed facilitates
the attackers access the ciphertext. This paper reveals an overview and study of providing security to cloud data using
key exposure.
