BlindEye: Physically Observable Cryptography

Conventional cryptography depends on keeping a key secret. This falls down when attackers have the physical hardware, such as the Smart Cards in which the key is embedded: if the key is present, then it can be read by a combination of FIB, light attacks, side channel attacks, rear surface atomic force microscopy, Kelvin probles.What is needed is a solid platform with a strong formal basis that eliminates these issues, closing the security gap of conventional cryptography. BlindEye is unique in meeting that requirement.

BlindEye technology provides provable protection for applications such as smart cards and media, even when the attacker has access to unlimited physical media and full knowledge of the implementation: cryptography that withstands attack right down to the gate level on the chip holding the private key - with BlindEye there is no private key stored - specific keys are synthesised from biometrics, PINs and other data that is not on any physical device.

Unlike algorithmic cryptography, BlindEye does not afford the attacker visibility of any data: there is zero information content in the side-channels. Even if the attacker captures the data as it is transmitted between peers, decoding the data is frustrated because the data itself becomes unobservable. Without having the synthesised key at the time the data is present, there is no clock-data eye: a fundamental requirement for conveying information across a channel. Similarly, light attacks are defeated because there is no stored data to observe, and single place which recreates data.

The BlindEye Evaluation card allows third party assessment of BlindEye solutions at five levels covering physical cryptography applications from password synthesis through to off-chip communication:

BlindEye is supported by both Partner Programmes and Evaluation Cards.

Evaluation Card Features: Two complete peers: Bob and Alice Each peer can perform internal and external transfers, over RS485 and optical channels BlindEye ON / OFF for pipeline transfers BlindEye ON / OFF for State Machines BlindEye ON / OFF for copper serial data BlindEye ON / OFF for unidirectional and bidirectional optical data BlindEye ON / OFF for password resynthesis The user has the opportunity to inject faults directly into FPGAs: the card is supplied with manuals, schematics and source code. A datasheet on the evaluation card may be downloaded by clocking on the image on the right. Email sales@deeplife.co.uk for information on partner programmes. .
