Map Reduce environments like Hadoop does not have any built in security mechanism. Anyone having access to the datanode can easily read content of the file. As a result out sourcing map reduce jobs is potentially risky and might not be appropriate in certain circumstances.
To solve this short comings we propose a platform that can securely execute exact match and range queries with map reduce jobs. In our case we assume that the map jobs run in non-secure nodes and reduce jobs are run in secure nodes and all the data is encrypted.
