为什么在 TSS. Java 项目中使用 tpm.EvictControl()方法运行出错，并显示以下消息：{NO_SESSIONS}，有没有了解的进来提点提点

用的是微软的 TSS.java 开发工具包，做个 TPM 可信模块开发，遇到的问题，源码如下：

public static void main(String[] args) throws IOException { Tpm tpm = TpmFactory.platformTpm(); byte[] nullVec = new byte[0]; byte[] aesKey = Helpers.RandomBytes(16); TPMT_PUBLIC aesTemplate = new TPMT_PUBLIC(TPM_ALG_ID.SHA256, new TPMA_OBJECT(new TPMA_OBJECT[]{TPMA_OBJECT.decrypt, TPMA_OBJECT.sign, TPMA_OBJECT.fixedParent, TPMA_OBJECT.fixedTPM, TPMA_OBJECT.userWithAuth}), new byte[0], new TPMS_SYMCIPHER_PARMS(new TPMT_SYM_DEF_OBJECT(TPM_ALG_ID.AES, 128, TPM_ALG_ID.CFB)), new TPM2B_DIGEST_SYMCIPHER()); TPMS_SENSITIVE_CREATE sensCreate = new TPMS_SENSITIVE_CREATE(nullVec, aesKey); CreatePrimaryResponse aesPrimary = tpm.CreatePrimary(tpm._OwnerHandle, sensCreate, aesTemplate, nullVec, new TPMS_PCR_SELECTION[0]); TPM_HANDLE aesHandle = aesPrimary.handle; byte[] toEncrypt = new byte[]{1, 2, 3, 4, 5, 4, 3, 2, 12, 3, 4, 5}; byte[] iv = new byte[16]; EncryptDecryptResponse encrypted = tpm.EncryptDecrypt(aesHandle, (byte) 0, TPM_ALG_ID.CFB, iv, toEncrypt); EncryptDecryptResponse decrypted = tpm.EncryptDecrypt(aesHandle, (byte) 1, TPM_ALG_ID.CFB, iv, encrypted.outData); System.out.println("AES128 encryption with key = " + Helpers.toHex(aesKey)); System.out.println(" Input data:" + Helpers.toHex(toEncrypt)); System.out.println(" encrypted data:" + Helpers.toHex(encrypted.outData)); System.out.println(" decrypted data:" + Helpers.toHex(decrypted.outData)); // persistent handle TPM_HANDLE persistentHandle = TPM_HANDLE.persistent(0x81010001); tpm.EvictControl(TPM_HANDLE.from(TPM_RH.OWNER), aesHandle, persistentHandle); if (!Helpers.arraysAreEqual(toEncrypt, decrypted.outData)) { throw new RuntimeException("encrypt/decrypt failed!"); } else { tpm.FlushContext(aesHandle); } // clean object if (!Helpers.arraysAreEqual(toEncrypt, decrypted.outData)) { throw new RuntimeException("encrypt/decrypt failed!"); } else { tpm.FlushContext(aesHandle); } } 

错误信息如下：

Exception in thread "main" tss.TpmException: Unexpected response tag {NO_SESSIONS} at tss.TpmBase.DispatchCommand(TpmBase.java:391) at tss.Tpm.EvictControl(Tpm.java:1930) at com.xxx.assist.XXXX.main(XXXX.java:12)
