We are looking for a developer with experience in cryptography and "byte-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. Writing the unit tests to validate that it works is also part of the project. Also, there is a C implementation available which can be used as reference. (This does only do the forward transformation though).
JNI is currently not an option for us, since it makes the library less portable.
As result of this project we would like to have working and documented java source code, backed up with unit tests.
More information about the spec is found in attached document, Annex A. The Test vectors are in Annex C.
