摘要： A system and method of providing secure communications is provided. Messages are encrypted or decrypted in protected memory of a processor. Outbound messages from a secure network are prepared for encryption by adding a header outside of the protected memory and then encrypted in the protected memory. The encryption is performed by retrieving a key from a key cache as designated by rules in the header. The encrypted message is sent to the unsecure network. An inbound message from an unsecure network that is received in unprotected memory is sent to a decryption module in protected memory. The inbound message is decrypted using a key designated in its header and retrieved from the key cache. The decrypted message is returned to the unprotected memory, where it is stripped of the encryption header and then sent to its destination within the secure network.
摘要翻译：提供了提供安全通信的系统和方法。消息在处理器的受保护的存储器中被加密或解密。来自安全网络的出站消息通过在受保护的存储器之外添加头部然后在受保护的存储器中加密来准备加密。通过从标题中的规则指定的密钥缓存中检索密钥来执行加密。加密的消息被发送到不安全的网络。在未受保护的存储器中接收到的来自不安全网络的入站消息被发送到受保护存储器中的解密模块。使用在其报头中指定的并从密钥高速缓存中检索的密钥解密入站消息。解密的消息被返回到不受保护的存储器，其中它被剥离加密头部，然后在安全网络内发送到其目的地。

摘要： An initiating device: generates a message having an ISAKMP-based header that includes a security parameter index (SPI) field; identifies a key in the SPI field of the ISKMP-based header; and sends the message to a responding device. The responding device: receives the message; extracts the key identifier; and when a shared key is selected using the key identifier, uses the selected shared key to establish, with the initiating device, a session having a secure tunnel.
摘要翻译：发起设备：生成具有基于ISAKMP的报头的消息，该报头包括安全参数索引（SPI）字段; 识别基于ISKMP的头部的SPI字段中的键; 并将消息发送到响应设备。响应设备：接收消息; 提取密钥标识符; 并且当使用密钥标识符选择共享密钥时，使用所选择的共享密钥与发起设备建立具有安全隧道的会话。
