如何获取cpu序列号

我想获取cpu的序列号用来实现我的软件加密，希望各位大哥大姐帮忙。但是如果是类似以下的代码就不要贴出来了，因为它获得的是cpu编号，不是序列号，同一批次出厂的cpu的编号是相同的，它无法满足我实现加密的要求。谢谢！

  public static string GetComputerId()
        {

            string sProcessorID = "";
            string diskID = "";

            string sQuery = "SELECT ProcessorId FROM Win32_Processor";

            ManagementObjectSearcher oManagementObjectSearcher =

                new ManagementObjectSearcher(sQuery);

            ManagementObjectCollection oCollection = oManagementObjectSearcher.Get();

            foreach (ManagementObject oManagementObject in oCollection)
            {

                sProcessorID = (string)oManagementObject["ProcessorId"];

            }

            return (sProcessorID);
        }

  public static string GetComputerId()
        {

            string cpuInfo = "";//cpu序列号 
            ManagementClass cimobject = new ManagementClass("Win32_Processor");
            ManagementObjectCollection moc = cimobject.GetInstances();
            foreach (ManagementObject mo in moc)
            {
                cpuInfo = mo.Properties["ProcessorId"].Value.ToString();
            }
            return cpuInfo;
        }
