ECDA签名验证失败

Question

我正在签署Javacard小程序上的一些数据，然后在PC上的Java中对其进行验证。为了测试这一点，我有一条消息，我知道应该验证，但是在运行代码验证时会失败。

这是我的代码：

//message = byte array of message from java card
//signature = byte array of signature from java card

BigInteger bigIntX = new BigInteger(1, xArray);
BigInteger bigIntY = new BigInteger(1, yArray);
boolean verified = false;

ECPoint w = new ECPoint(bigIntX, bigIntY);

KeyFactory newKeyFact = KeyFactory.getInstance("EC");
ECNamedCurveParameterSpec paramSpec = ECNAMEDCurveTable.getParameterSpec("secp256r1");
ECParameterSpec params = new ECNamedCurveSpec("secp256r1", paramSpec.getCurve(), paramSpec.getG(), paramSpec.getN(), paramSpec.getH());
ECPublicKey ecPublicKey - (ECPublicKey) newKeyFact.generatePublic(new ECPublicKeySpec(w, params));

Signature sig = Signature.getInstance("SHA256withECDSAinP1363Format");
sig.initVerify(ecPublicKey);
sig.update(message);
verified = sig.verify(signature);

if (verified) {
//print True
} else {
//print false
}

验证永远不会设置为True，即使我知道此消息应该验证正常。我是否重新构建了钥匙？还是我缺少其他东西？

这是我的javacard代码生成签名的代码：

KeyPair key = new KeyPair(KeyPair.ALG_EC_FP, KeyBuilder.LENGTH_EC_FP_256);

ECPublicKey pubKey = (ECPublicKey) key.getPublic();
ECPrivateKey privKey = (ECPrivateKey) key.getPrivate();
initDomainParams(pubKey);
initDomainParams(privKey); //initDomainParams is just where I set A, B, G, R and K to the secp256r1 curve parameters using setA, setB etc

key.genKeyPair();
Signature sig = Signature.getInstance(Signature.ALG_ECDSA_SHA_256, false);
sig.init(key.getPrivate(), Signature.MODE_SIGN);
sig.sign(srcArr, srcoffset, srclength, destArr, destoffset);
