Problems solved by technology

At the same time, there are roughly two key negotiation methods: RSA public key encryption method and Diffie-Hellman key negotiation method. Due to the energy and storage space limitations of wireless sensor nodes, encryption algorithms such as RSA and ECC are difficult to implement in nodes. TLS The use of the SASL handshake mechanism is limited, and the security of the authentication methods used in the SASL handshake mechanism, such as PLAIN (RFC4616) and EXTERNAL (RFC2222), cannot be guaranteed
In addition, the TLS handshake mechanism requires up to a dozen message interactions, coupled with the SASL mechanism, the communication overhead is too large, and it is suitable for energy-constrained wireless sensor networks

Abstract

The invention provides a sensor network based XMPP security access method which is applicable to an authentication mechanism-DIGEST-AES security mechanism of a wireless sensor network. The sensor network based XMPP security access method comprises the steps that an XMPP node and an XMPP server perform key negotiation and the XMPP node is accessed to authentication and authorization service at an initialization phase. According to the sensor network based XMPP security access method, a low-expenditure security algorithm is introduced while the original protocol structure and the communication mode of an XMPP are ensured, a message exchange process is simplified, the XMPP node and the XMPP server of the sensor network can safely and effectively establish XML stream, and security functions including equipment registration, key negotiation, authorization, authentication and the like based on the XMPP are achieved. Compared with a traditional XMPP security mechanism, the communication expenditure of the security mechanism is remarkably reduced.

Description

Technical field [0001] The invention relates to the field of wireless sensor networks, in particular to a method for secure access of sensor network nodes based on the XMPP protocol. Background technique [0002] XMPP (Extensible Messaging and Presence Protocol, formerly known as Jabber) is an open real-time communication protocol based on XML and an Internet standard adopted by the Internet Engineering Task Force (IETF). The XMPP protocol has the characteristics of openness and scalability, which makes its application in wireless sensor networks have a broader prospect. [0003] The XMPP protocol uses an open protocol, which makes it more helpful for wireless sensor networks to achieve the standardized information transmission goals of things to things and people to things; as an application layer protocol, the use of XMPP can also meet the needs of wireless sensor networks. Application diversification needs, but also more conducive to service expansion; In addition, XMPP uses a ...
