Searching Encrypted Data
Company data are very often outsourced to datacentres in order to lower costs of maintaining hardware. If the outsourced data are to be kept secure from a third party, the connection between the datacentre and the company could be secured by a protocol similar to SSL. This, however, requires that the data is stored at the datacentre in plaintext form, meaning the company has to trust the datace...
متن کاملEncrypted Shared Data Spaces
The deployment of Share Data Spaces in open, possibly hostile, environments arises the need of protecting the confidentiality of the data space content. Existing approaches focus on access control mechanisms that protect the data space from untrusted agents. The basic assumption is that the hosts (and their administrators) where the data space is deployed have to be trusted. Encryption schemes ...
متن کاملSearching Encrypted Data on Cloud
Encryption is an optimistic way to preserve the secrecy of the outsource data. On other hand, performing search operation on encrypted data is a complicated job. A lot of encryption techniques have been suggested by researchers to avoid improper usage of unstructured data on the cloud. But still by using the existing searchable encryption techniques, searching data on cloud server becomes diffi...
متن کاملPrivate Searching on Encrypted Data in Cloud
Cloud computing appeared as the most common paradigm in the time being that provides calculations and storage resources by when used – pay method. Users can exploit cloud resources from anywhere at any time without maintenance cost. Flexibility in resource allocation enabled cloud services to be effective in delivering with reasonable cost. However, transfer data to cloud make it vulnerable to ...
متن کاملSearching Keywords with Wildcards on Encrypted Data
A hidden vector encryption scheme (HVE) is a derivation of identity-based encryption, where the public key is actually a vector over a certain alphabet. The decryption key is also derived from such a vector, but this one is also allowed to have “?” (or wildcard) entries. Decryption is possible as long as these tuples agree on every position except where a “?” occurs. These schemes are useful fo...
