ECCelerate 4.0 released!

13/10/2016

We proudly present a new maintenance release of our new IAIK ECCelerate™ elliptic curve library! Version 4.0 greatly improves the overall performance! It is based on the latest standards and replaces our old IAIK-ECC library. IAIK ECCelerate™ is based on Java 6 technology and has been thoroughly optimized for speed. Currently, it supports ECDSA, ECDH, ECIES and optionally ECMQV.

PKCS#11 Wrapper

This is a library for the Java™ platform which makes PKCS#11 (also known as Cryptoki) modules accessible from within Java™. A PKCS#11 module is a software library with a defined API which allows access to cryptographic hardware. It usually comes with hardware security modules (HSM), smart cards and crypto tokens (e.g. USB tokens). Thus, the PKCS#11 Wrapper provides Java™ software access to almost any crypto hardware. For example, a Java™ application can use it to integrate a HSM or a smart card to create digital signatures, to decrypt data or to unwrap keys. We provide this library with an apache-style license.

Please notice that this library does not come with a JCA or JCE provider implementation. For this purpose there is a different product – the IAIK PKCS#11 Provider .

The Layer Model of the System

Figure 1 shows the layer model of this library. This library consists of the Object Oriented (OO) Wrapper API for PKCS#11 for the Java™ platform, the (non-Object Oriented) Wrapper API for PKCS#11 for the Java™ platform and the Native Module of the Wrapper, the green layers in the figure. The following paragraphs describe these parts. The lowest layer, the PKCS#11 Module of the Smart Card, is the PKCS#11 module that the smart card manufacturer supplies. This is normally a DLL or shared library. As the arrows show, the uppermost layer depends on the Wrapper for PKCS#11 for the Java™ platform, but not vice versa. This means you can use the Wrapper for PKCS#11 for the Java™ platform directly and build your application upon it without using the OO layer. This can be useful to create smaller applications, because you do not need most of the classes of the package iaik.pkcs.pkcs11 and no class from iaik.pkcs.pkcs11.objects and iaik.pkcs.pkcs11.parameters. The only classes from iaik.pkcs.pkcs11 you need are the exception classes.

The Object-Oriented API for PKCS#11 for the Java™ platform

This object-oriented API for the Java™ platform resides in the packages iaik.pkcs.pkcs11, iaik.pkcs.pkcs11.objects and iaik.pkcs.pkcs11.parameters. It provides a straight forward mapping of the PKCS#11 v2.20 standard to a set of classes and interfaces. The package iaik.pkcs.pkcs11.objects is a model of the object hierarchy presented in this PKCS#11 standard. The package iaik.pkcs.pkcs11.parameters provides classes for objects that act as parameters for mechanisms which require specific arguments. This layer solely builds upon the API for the Java™ platform for PKCS#11 as implemented by the Wrapper for PKCS#11 for the Java™ platform.

The API for PKCS#11 for the Java™ platform

The non-Object Oriented Wrapper API for PKCS#11 for the Java™ platform is a set of Java™ classes and interfaces that reflects the PKCS#11 API. It is a straightforward realization of the data structures as defined in PKCS#11. For each structure in the pkcs11t.h header file of PKCS#11, there is a corresponding class in the package iaik.pkcs.pkcs11.wrapper. Notice, that this is not an object oriented approach at this level; it is just a straightforward mapping of the data structures to Java™. All adoptions to the PKCS#11 API, including wrapping into an object oriented approach, appear in the Object Oriented Wrapper API for PKCS#11 for the Java™ platform. The interface PKCS11 in the iaik.pkcs.pkcs11.wrapper package is the interface to a PKCS#11 module and provides access to the functions defined by PKCS#11. All names of classes, data structures and methods are the same as the corresponding PKCS#11 counterpart. The PKCS11Connector instantiates an object that implements this PKCS11 interface. The returned object gives access to the PKCS#11 module of the smart card; it is the Java™-Counterpart to the CK_C_GetFunctionList returned by the C_GetFunctionList function in PKCS#11. The Module class in the object-oriented layer provides the respective functionality. Have a look at the demo.pkcs.pkcs11 package in the demo directory for sample programs.

The Native Module of the Wrapper

 This native module of the wrapper is responsible for translation of the Java™ data structures, which the API for PKCS#11 for the Java™ platform part defines, to native PKCS#11 data structures and vice versa. This module of the system does not include any additional logic, it only provides a straightforward mapping from the API for PKCS#11 for the Java™ platform to the PKCS#11 Module of the Smart Card. This layer is necessary, because the JNI requires the native functions to have a special signature that is defined by JNI itself. PKCS#11 and JNI are not compatible as they are, and this is the reason why this layer is necessary at all. In compiled form, this module is a native DLL or shared library.

Includes:

 Full source of all components under an Apache-style license as well as precompiled binaries for Windows, Linux, Solaris 8/9/10 and Mac OS X.

Requirements:

 JDK 1.3 or higher, GNU make for building the project using the included make files, MS VC++ 6.0 for building the DLLs for Windows, GCC for building the shared libraries for Linux and Solaris (or SUN C compiler).
 Some of the included demo programs require the IAIK-JCE to compile and run. Simply place the iaik_jce_full.jar in the examples\lib directory.
