Strong Encryption, Natural Language Search Make Potent Cocktail
Encrypted data may be relatively safe from prying eyes, but it's often inaccessible to authorized users as well. "Encryption can break an application," said CipherCloud CEO Pravin Kothari. "It can make an application useless." Through a gateway between an organization and its encrypted data in the cloud, CipherCloud allows applications to work with the encrypted data as if were plain text.

Strong encryption and natural language search can be like oil and water. That's because encrypted data can't be digested by your typical search engine. However, CipherCloud announced a solution to that knotty problem last week.
The latest version of the 3-year-old company's cloud-based service includes something it's calling "searchable strong encryption." It allows data encrypted with the strong AES 256-bit standard to be searched within popular cloud applications such as Salesforce.com, Box, Microsoft Office 365, Google Gmail and Amazon Web Services.
"Encryption can break an application," Pravin Kothari, founder, chairman and CEO of CipherCloud, told TechNewsWorld. "It can make an application useless."
Through the use of a gateway between an organization and its encrypted data in the cloud, CipherCloud allows applications to work with the encrypted data as if were plain text.
"If you looked into the cloud application, what you would see is gibberish -- but using our gateway architecture, we can allow all popular operations, like search, and give a user the full usability of the application," Kothari explained.
"Customers had to previously choose between protection of their data and usability of an application," CipherCloud SVP and Chief Marketing Officer Paige Leidig told TechNewsWorld. "With our new product, they can get the best of both worlds -- highest security of their data and full searchability and sortability of the data."
With SSE, CipherCloud has improved how it deploys AES 256. In prior versions of the solution, it used limited initialization vectors. Those vectors are used to randomize encrypted or ciphertext. So depending on the vector of your starting point for encrypting a block of data, the word "John" might be 6324 in one block and 7745 in another. That makes it difficult for codebreakers to correlate the ciphertext to its plaintext analog.
The problem with limiting your initialization vectors is that it makes a codecracker's job easier, because there's a finite set of points that need to be identified. CipherCloud has now made things much more difficult for crackers, by allowing its users to encrypt their data with unlimited initialization vectors.
In light of recent revelations about the NSA tampering with encryption standards, it's questionable whether any standard is trustworthy.
"People are concerned about everything, but AES in any of its sizes is pretty low on the list," Matthew Green, a professor specializing in cryptography in the computer science department of Johns Hopkins University, told TechNewsWorld.
"AES was developed in an international competition by Belgian cryptographers. It has been really well analyzed by the security community, and it has a good design," Green added.
The Freedom of the Press Foundation announced last week that it would be soldiering on with technology developed by the late Aaron Swartz to give whistleblowers safe online places to drop leaked documents to news outlets and maintain their anonymity.
The technology, called "SecureDrop," has become more important than ever because of the Obama's administration's tough attitude toward people leaking state secrets.
"This is coming about because of the Obama White House's really unhealthy obsession with leaks," Dan Kennedy, and assistant professor of journalism at Northeastern University, told TechNewsWorld.
"If the Obama administration weren't going after leakers and the journalists who they leak to as vigorously and inappropriately as they are, then you wouldn't need something like this," he maintained.
There are some inconsistencies in the administration's attitude toward whistleblowers, though.
"It's worse than all other administrations in terms of national security whistleblowing," Louis Clark, president of the Government Accountability Project, told TechNewsWorld.
"I think it's the best administration in terms of corporate whistleblowers," he continued. "So it's a schizophrenic administration."
In the current agency climate technologies like SecureDrop have become a necessity for whistleblowers, Clark noted.
"The treatment of whistleblowers has angered some people in the national security agencies," he said. "Whistleblowers feel like they have nowhere to go in their agencies, and when that happens, there's no place they can go except for the public if they want to raise their concerns."
