Java Library for CCM* encryption/decryption

We are looking for a developer with experience in cryptography and low-level java development with a focus on performance. The project is to develop a library that can encrypt and decrypt byte arrays using a supplied standard called CCM*. This is a variation on AES-CCM block cipher mode.

The CCM* mode coincides with the original CCM mode specification for messages that require authentication and, possibly, encryption, but does also offer support for messages that require only encryption. As with the CCM mode, the CCM* mode requires only one key.

There is an extensive specification which also includes test vectors that should serve as input for unit tests. Also, there is a C implementation available which can be used as reference.

As result of this project we would like to have clean, working and documented java source code, backed up with unit tests.

Skills: Cryptography, Java, Software Testing
