ECDH1_DERIVE PCKS11interop 和 Safenet Network HSM 的问题

Question

与 Gemalto 网络 HSM 斗争了一段时间，是时候寻求专家帮助了。我正在尝试从一个已知的 public 密钥和一个存储在 HSM 上的私钥派生出一个 ECDH1 密钥，并不断将 HSM 发送到某种恐慌模式，这需要我在它每次开始再次通话之前重置它如下所述调用派生密钥函数。有人有任何指示吗？

static string PKCSLibraryPath = @"C:\Program Files (x86)\SafeNet\Protect Toolkit 5\Protect Toolkit C SDK\bin\hsm\cryptoki.dll";
    static Pkcs11 pkc = new Pkcs11(PKCSLibraryPath, AppType.SingleThreaded);

    public string HSM_Interaction(int SlotNumber, string KeyLabel, string Pubkey, string GUID)
    {

        List<Slot> slots = pkc.GetSlotList(SlotsType.WithTokenPresent);
        string pass = "1111";

        //convert putblic key to byte array
        byte[] data = Get_pub_Key(Pubkey);

        //convert password to byte array
        byte[] password = Encoding.ASCII.GetBytes(pass);

        //select correct HSM slot
        Slot S = slots[SlotNumber];

        using (Session Sesh = S.OpenSession(SessionType.ReadWrite))
        {

            Sesh.Login(CKU.CKU_USER, password);

您收到的异常表明低级别 PKCS#11 函数 C_DeriveKey 返回了供应商特定错误 0x80000384（2147484548 十月），称为 CKR_SMS_ERROR。您将需要讨论设备供应商提供的文档或联系供应商支持以更好地了解如何处理或避免此特定错误。

这个确切的错误 was also discussed in an older question 是由于在多线程环境中不正确使用 PKCS#11 API 引起的。
