  Cloud computing is the broad and diverse phenomenon. Users are allowed to
store huge amount of data on cloud storage for future use. Most of the cloud
service providers store data in plain text format or in secured manner but
client will not be known the method in which it is stored. Homomorphic
encryption is the encryption which allows the operation on cipher text thus
generating an encrypted result which when decrypted, matches the result of
operations performed on the plaintext. This is sometimes a desirable feature in
modern communication system architectures. There are several homomorphic
algorithms, one of them is AHEE. User need to use their own encryption
algorithm to secure their data if required. The data needs to be decrypted
whenever it is to be processed. In this paper, we have focused on providing
security to the client using AHEE algorithm at the client side, for any data to
be stored in the cloud.
