Embodiment Construction
[0043] Various preferred embodiments of the present invention will be described in more detail below in conjunction with the accompanying drawings.
[0044] The method for secure encapsulation of network messages in the present invention does not involve the negotiation process of security associations. After the secure encapsulation protocol of the message obtains arbitrarily long network messages, it performs encapsulation, encryption, and authentication processing, and finally forms an encrypted The application layer message for integrity check is sent to the transport layer for sending.
[0045] The encapsulation format example description of the network message of the inventive method is as follows:
[0046] First, the original signaling message is encapsulated, and the format of the encapsulated message is:
[0047] struct{
[0048] uint48 seq_num;
[0049] uint16 length;\\fragment length;
[0050] opaque fragment[SignalPlaintext. length]...
