Abstract
A method implements searchable encryption of cloud stored data by appending tokenized keywords to an encrypted file destined for a cloud storage service. In some embodiments, the tokenized keywords are appended to the header of the encrypted file. Searching of cloud-stored encrypted files using the native search capability of the cloud storage service is then possible by performing the search using the tokenized keywords. In alternate embodiments of the present invention, a method enables searching of cloud stored encrypted file using a cloud search appliance.
