The method comprises the following steps of: 1, converting an SM2 signature waiting to be authenticated into a corresponding ECDSA signature; 2, authenticating the ECDSA signature obtained by conversion by using the ASIC chip in which the ECDSA is adopted; and 3, performing out-chip modular ...
在计算了消息的哈希值之后,我们可以使用私钥对哈希值进行签名。在Java中,可以使用Signature类来进行签名操作。下面的代码示例展示了如何使用Signature类进行SM2签名: AI检测代码解析 Signaturesignature=Signature.getInstance("SM3withSM2","BC");signature.initSign(privateKey);signature.update(hash);byte[]signatureValue...
