The embodiment of the invention provides an inter-gateway data transmission method, a source gateway and a destination gateway. The method comprises the following steps: acquiring a trust gateway list of the destination gateway; judging whether identifier information of the source gateway is in the trust gateway list of the destination gateway; if the identifier information of the source gateway is in the trust gateway list, judging the authentication corresponding to the identifier information of the source gateway is expired; if the authentication corresponding to the identifier information of the source gateway is unexpired, not performing the identity authentication, sending a first data request to the destination gateway, wherein the first data request carries the identifier information of the source gateway; if the identifier information of the source gateway is not in the trust gateway list of the destination gateway or the authentication corresponding to the identifier information of the source gateway has expired, encrypting the first data request by use of a RSA algorithm to form a second data request, and sending the second data request to the destination gateway, wherein the second data request carries the identifier information of the source gateway, thereby enabling the destination gateway to perform the identity authentication on the second data request.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a data transmission method between gateways, a source gateway, and a destination gateway. Background technique [0002] With the rapid popularization and application of the network, people pay more and more attention to information security. As an important part of information security, the gateway is particularly important to ensure the security of data transmission between gateways. [0003] In the existing technology, the transmission of information between different domains needs to pass through the IP network. In order to ensure data security and confidentiality, the gateway as an application server needs to perform encryption, decryption and digital signature operations on the data received or forwarded inside and outside the domain. Security guarantees for identity authentication, information confidentiality and integrity. [0004] H...
