Different encryption algorithms in cloud

Big data is something which has a huge amount of data that has to be processed. It handles all types of data may it be of any volume which may be further any types of data. It may be structured or unstructured or may be semi structured. Big data is used to get together the old and new data. There are tools designed to handle this huge data like Apache Hadoop. But the data kept over the internet is not safe. Cloud whereas provides the online storage system but providing the security is still an issue. Encryption and decryption is the old approach to provide the security to the data. Here, I will be discussing about the various encryption techniques available.
