Welcome to CrySIL - the Cryptographic Service Interoperability Layer

The Crypto Service Interoperability Layer (CrySIL) concept has been created to meet today's heterogeneous device landscape and allows the user to use her keys within cryptographic operations, regardless where the key resides and where it is needed.

In a nutshell, the user takes one of her devices and launches an application to perform some cryptographic task. The application interfaces with the interoperability layer, CrySIL, which connects to another device. This other device has access to the actual cryptographic primitive, creates and validate authentication challenges if required and performs the requested operation. The result is returned to the interoperability layer and back to the application running on the device of the user.

Please find below a list of publications having CrySIL somewhere in their scope.
