public class CMSSSignature
extends Signature

This class implements the CMSS2 signature scheme. The class extends the SignatureSpi class. It is able to use the SPR hash functions as described in E. Dahmen et al., "Digital Signatures Out of Second-Preimage Resistant Hash Functions".

The CMSS2Signature can be used as follows:

Signature generation:

1. generate KeySpec from encoded CMSS2 private key:
KeySpec privateKeySpec = new PKCS8EncodedKeySpec(encPrivateKey);
2. get instance of CMSS2 key factory:
KeyFactory keyFactory = KeyFactory.getInstance("CMSS2","FlexiPQC");
3. decode CMSS2 private key:
PrivateKey privateKey = keyFactory.generatePrivate(privateKeySpec);
4. get instance of a CMSS2 signature:
Signature cmmsSig = Signature.getInstance("SHA1andWinternitzOTS_1","FlexiPQC");
5. initialize signing:
cmssSig.initSign(privateKey);
6. sign message:
cmssSig.update(message.getBytes());
signature = cmssSig.sign();
return signature;

Signature verification:

1. generate KeySpec from encoded CMSS2 public key:
KeySpec publicKeySpec = new X509EncodedKeySpec(encPublicKey);
2. decode CMSS2 public key:
PublicKey publicKey = keyFactory.generatePublic(publicKeySpec);
3. initialize verifying:
cmssSig.initVerify(publicKey);
4. Verify the signature:
cmssSig.update(message.getBytes());
return cmssSig.verify(signature);

Method Detail

initSign

public void initSign(PrivateKey key,
                     SecureRandom random)
              throws InvalidKeyException
Initialize the signature algorithm for signing a message.
Overrides:
initSign in class Signature
Parameters:
key - the private key of the signer
random - a source of randomness (not used)
Throws:
InvalidKeyException - if the key is not an instance of OTSPrivateKey.

initVerify

public void initVerify(PublicKey key)
                throws InvalidKeyException
Initialize the signature algorithm for verifying a signature.
Overrides:
initVerify in class Signature
Parameters:
key - the public key of the signer.
Throws:
InvalidKeyException - if the public key is not an instance of CMSS2PublicKey.

setParameters

public void setParameters(AlgorithmParameterSpec params)
Initialize this signature engine with the specified parameter set (not used).
Overrides:
setParameters in class Signature
Parameters:
params - the parameters (not used)

update

public void update(byte data)
Feed a message byte to the message digest.
Overrides:
update in class Signature
Parameters:
data - array of message bytes

update

public void update(byte[] data,
                   int offset,
                   int length)
Feed message bytes to the message digest.
Overrides:
update in class Signature
Parameters:
data - array of message bytes
offset - index of message start
length - number of message bytes

sign

public byte[] sign()
            throws SignatureException
Sign a message.
Overrides:
sign in class Signature
Returns:
the signature.
Throws:
SignatureException - if no more signatures can be generated with the private key.

verify

public boolean verify(byte[] sigBytes)
Verify a signature.
Overrides:
verify in class Signature
Parameters:
sigBytes - the signature to be verified.
Returns:
true if the signature is correct, flase otherwise
