New protocol from Guardtime hopes to unseat RSA for authentication, digital signatures

BLT protocol promises tighter security, easier management.

He says it can be used not only to verify the integrity of, say, a sensor in a network, but also the data gathered by the sensor. That makes it possible to verify that the data collected matches the data delivered from the sensor.

Ericsson's service is being offered only to limited customers right now but will be rolled out generally to customers in North America and Europe next year, Hoffman says.

BLT will be available on Black Lantern gear this fall.

Based in Estonia, Guardtime was founded in 2006 and backed privately by Gault initially, but by other private investors since then. Gault, a former derivatives trader, met the Estonian researchers while he was a graduate student in Japan, heard about their scheme and relocated to Estonia to help with the company.

Guardtime says its annual revenue has grown from $100,000 in 2012, to $10 million last year. Revenues for the first quarter of this year were $20 million, it says.
