数据在网络传输过程中可能会被他人窃取或篡改,从而造成泄密或重大经济损失,SOAP消息在传输时同样存在这样的安全隐患。本文设计了基于XML格式的安全引擎模型,由XML格式驱动、XML加密、解密、签名、验证、和内容过滤等几部分组成,保证了SOAP消息在网络上传送的安全性。 Data may be stolen or tampered with by others while the data is being transmitted over the network, resulting in leakage or significant financial loss. This also poses a potential security risk when transmitting SOAP messages. This paper designs a security engine model based on XML format, which is composed of XML format driver, XML encryption, decryption, signature, authentication, and content filtering, which ensures the security of SOAP message delivery on the network.
