Problems solved by technology

[0006] The current mainstream approach is to prevent DoS (Denial of Service, denial of service attack) by configuring and disabling the renegotiation function, but this will make the features that rely on renegotiation unusable; Negotiation flexibility; or limit the rate of new incoming TLS connections and re-negotiations; and if the limit is only unilateral, and the other party does not know that there is this limit, there will be unnecessary waste of communication resources and failure to timely Prevent illegal attacks

Embodiment Construction

[0043]Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .

[0044] The present invention provides a registration method for preventing re-negotiation DoS attacks. In this embodiment, after the conference terminal to be registered actively establishes a TCP connection to the registration server, both parties complete the TLS handshake process; and then perform the registration process based on a secure TLS channel ,Such as figure 1 shown, including the following steps:

[0045] S11. The conference terminal sends a registration request to the server, wherein the registration request is configured with the field information of the TLS renegotiation time interval expected by the conference terminal; image 3 As sh...

Abstract

The invention provides a registration method for preventing re-negotiation DoS attack, a calling method, a storage medium and an electronic device. According to the invention, the re-negotiation rateis controlled; the existing SIP signaling is simply expanded to realize the negotiation of the re-negotiation rate; different re-negotiation rates are distributed according to the importance level ofthe conference, can be updated and negotiated, and are compatible with emergency re-negotiation characteristics under special conditions and standard video conference SIP interaction processes which do not support the extended fields. The difficulty and complexity of key cracking are increased by supporting re-negotiation, so that the safety of connection is guaranteed, and the safety of communication contents under the condition of long-time video conferences by double transmission of communication is greatly guaranteed. The attributes of an encryption and decryption layer are set through interaction of SIP signaling of an application layer, so that the re-negotiation rate is controlled, and the possibility of DoS attack caused by inherent vulnerability characteristics in a video conference is solved.

Description

technical field [0001] The invention relates to the field of electronic communication, in particular to a solution, a storage medium and an electronic device for preventing possible DoS attacks caused by TLS support for renegotiation during video conferencing using the Sip protocol based on the TLS connection. Background technique [0002] The SSL / TLS (Transport Layer Security) protocol is the foundation of modern Internet security. Any important Internet applications such as online banking, e-commerce, e-government, and e-medicine must be based on the security and security provided by SSL / TLS. Confidentiality and trusted mechanisms can function normally. SSL / TLS is a protocol based on a reliable network layer protocol TCP protocol. This protocol is to generate a secure connection between the client and the server. This connection is private, reliable and the two parties can communicate. Mutual authentication of both parties. Therefore, the SSL / TLS protocol has confidentia...
