We need to perform some cryptographic operations and I want to know what cryptographic librairies can fit my need.
The following is the context:
Given the fact that we have:
- An EC Private Key stored in the HSM
- An EC Public Key (public point)
- Encrypted AES key
- MAC calculated with the EC public key ECDH
We need to perform the following:
Calculate a shared point (K~X~, K~Y~) using ECKA-DH algorithm from the EC Private and EC Public Keys. (See BSI TR 03111)
Derive K~ENC~ and K~MAC~ using KDF2(x, l) with SHA-256. K~ENC~ is first 8 bytes of output. K~MAC~ is last 8 bytes of output. (See ISO/IEC 18033-2)- Verify the MAC over the encrypted AES key against MAC ==> MAC = AES-CMAC(Encrypted AES key || ValueA || ValueB, K~MAC~).
- Decrypt the encrypted AES key ==> AES key = AES-CBC(encrypted AES key, K~ENC~).
What cryptographic librairies will help calculate shared point baed on
the fact that the Private key is stored in the HSM?
Can Bouncy Castle be used jointly with IAIK PKCS#11 wrapper?
Can IAIK-JCE a commercial product from IAIK help on that?
Thank you for your help.
Best regards.
