Problems solved by technology

When there is a mixed deployment of the old version of HTTPS and HTTP2 protocols, in some scenarios, the server may wish to use a low-strength encryption suite for the old version of HTTPS to reduce the processing pressure on the server, which will lead to HTTP2 requests. handshake failed
In order to make the HTTP2 handshake successful, the cipher suite list is fixed in the form required by the HTTP2 protocol. For the HTTPS handshake, it will cause a large overhead during the handshake.

Embodiment 1

[0048] figure 1 It is a flow chart of a method for selecting a cipher suite in Embodiment 1, and the method includes:

[0049] The server receives the handshake request; when judging from the handshake request that the version number of the transport security layer protocol is less than the preset version number, the cipher suite corresponding to the HTTPS protocol is used for handshake processing.

[0050] This method also includes: when the server judges that the version number of the security transport layer protocol is greater than or equal to the preset version number according to the handshake request, when judging that there is no extended parameter of the application layer protocol negotiation ALPN in the client greeting message of the handshake request, use The cipher suite corresponding to the HTTPS protocol performs handshake processing.

Abstract

The invention discloses a cipher suite selection method and a cipher suite selection device used for a handshake processing process. The cipher suite selection method comprises steps that a handshakerequest is received by a server, and when a version number of a safety transmission later protocol is smaller than a preset version number according to the handshake processing process, a cipher suitecorresponding to a HTTPS protocol is used for the handshake processing. Compatibility of selection of a cipher suite list is realized during the handshake processing under an old version of HTTPS anda new version of HTTPS, and on the basis of the old version of HTTPS, the cipher suite having low safety strength and high performance is realized, and the HTTP2 handshake adopting the high-strengthcipher suite is also fully supported, and therefore the intelligent performance of the handshake processing process can be improved, and the successful handshake during the use of different versions of protocols is guaranteed, and costs can be saved.

Description

technical field [0001] The invention relates to the field of cloud computing processing, in particular to a method and device for selecting an encryption suite during handshaking processing. Background technique [0002] The security-oriented HTTP channel (Hyper Text Transfer Protocol over SecureSocket Layer, HTTPS) is a commonly used protocol in cloud computing processing systems, and new versions are constantly appearing with the development of technology. The HTTP2 protocol is a successor version of HTTP 1.1, developed based on the SPDY protocol proposed by Google, and the specific content of the protocol is regulated by RFC 7540. A significant difference between HTTP2 and the old version of HTTP is that when using encrypted communication based on the Transport Layer Security protocol (TLS), HTTP2 mandates the set of cipher suites that can be used, and Appendix A of RFC 7540 lists prohibited Suite list, HTTP2 prohibits most low-strength cipher suites. When there is a mi...
