Kolkata, April 12, 2017: Researchers at IIT-Kharagpur have developed a solution to access encrypted data on cloud server with keywords, without the need for decryption nor compromising the security of the system, a statement said on Wednesday.

The solution by the Secured Embedded Architecture Lab (SEAL) at IIT Kharagpur is pragmatic in the sense that it allows analytics on the encrypted data itself, it said, adding that this eliminates the need to decrypt the data or compromise system security.

“We need cryptosystems that allow searchable encryption, or more simply, keyword search over encrypted document collections and databases” said researcher Sikhar Patranabis at SEAL.

The research has led to Controlled Access Searchable Encryption (CASE), a new public-key searchable encryption, or the process of encoding a message or information in such a way that only authorised parties can access it.

“We are expecting to have a full-fledged prototype implementation of our controlled-access searchable encryption set-up by the end of 2017,” Patranabis said.

CASE allows a data owner to generate a controlled-search access that can restrict the search capabilities of a data user to a specific subset of documents in the collection.

“This prevents the vulnerability of the full data set. CASE also preserves the privacy of the underlying plain-text data under well-known cryptographic assumptions,” said Debdeep Mukhopadhyay, lead researcher of the project and Director of incubation at Embedded Security and Privacy Pvt Ltd. (ESP), STEP-IIT Kharagpur.

Data encryption which is used as solution to data security often makes data searching and data mining operations difficult.

The solution involving sending data back to the owner for decryption and returning to the same client, is time-consuming with high costs as it requires heavy bandwidth and storage capabilities.

It also under-utilises the computational ability of the cloud, which is usually much greater than that of individual devices.

CASE addresses the gap, say the researchers. (IANS)

Intel and Cray Collaborate With U.S. Government, Aims for Nation’s Fastest Computer

The world's current most powerful machine, the Summit supercomputer at Oak Ridge National Laboratory in Tennessee, contains chips from International Business Machines Corp. and Nvidia.

A U.S. government-led group is working with chipmaker Intel and Cray to develop and build the nation’s fastest computer by 2021 for conducting nuclear weapons and other research, officials said Monday.

The Department of Energy and the Argonne National Laboratory near Chicago said they were working on a supercomputer dubbed Aurora with Intel, the world’s biggest supplier of data center chips, and Cray, which specializes in the ultra-fast machines.

The $500 million contract for the project calls on the companies to deliver a computer with so-called exaflop performance — that is, being able to perform 1 quintillion (1,000,000,000,000,000,000) calculations per second.

If the project succeeds, Aurora would represent nearly an order of magnitude leap over existing machines that feature so-called petaflop performance, capable of doing 1 quadrillion (1,000,000,000,000,000) calculations a second.

It also heightens the stakes in a race in which the United States, China, the European Union and Japan have all announced plans to build exaflop-capable supercomputers.

One of Aurora’s primary functions would be simulating nuclear blasts, a pillar of weapons development since the ban of live detonation testings.

Aurora will be built with artificial intelligence capabilities for projects such as developing better battery materials and helping the Department of Veterans Affairs prevent suicides, Rick Stevens, an associate lab director with Argonne overseeing the exascale computing project, said during a news
briefing.

The project is a win for Intel, which will supply its Xeon CPU chips and Optane memory chips for Aurora.

Intel has been fending off rival U.S. chipmaker Nvidia Corp.’s rise in the chip content of supercomputers as the machines take on more artificial intelligence work. Nvidia’s chips are found in five of the world’s current top 10 supercomputers, though the Nvidia chips are found alongside chips from its rivals, according to TOP500, which ranks the machines.

The world’s current most powerful machine, the Summit supercomputer at Oak Ridge National Laboratory in Tennessee, contains chips from International Business Machines Corp. and Nvidia.

The source of chips for supercomputers has become a factor in trade tensions between the United States and China. The world’s third-fastest supercomputer — the Sunway TaihuLight in China — has chips developed domestically in China.

Chirag Dekate, an analyst with Gartner who studies the supercomputing market, said that despite the small contract size relative to Intel’s overall revenue, the work done on Aurora will eventually filter down to the company’s commercial customers.

“It’s not just a jingoistic race between the U.S. and China,” Dekate said. “The innovations that Intel is developing here will percolate down to other parts of its business.” (VOA)
