In recent day, the enormous usage of cloud services leads to much concerned on cloud security. This paper primarily considers the important aspect of cloud security based on encryption. The users perform secure search on cloud environment using this method. Data stored in cloud are encrypted which ensure the privacy of the user; the files are encrypted before uploading. At the time of searching the file user can provide keywords to search on encrypted data. This encryption scheme based on two types symmetric key and asymmetric key. The first model is using users own secret key to encrypt the file and upload that. The second model is used for file sharing user use public key of receiver. The receiver then uses his private key to search the data.
