Since Publish/Subscribe systems have the advantages of loose coupling, anonymity, many-to-many communication and scalability, they have gotten broad attention and deep research. As the number of participants in the network increases, security becomes an increasing concern. This paper proposes an encryption mechanism based on redundant attributes. The mechanism supports finding out the links with the problem of wire-sniffing when the sensitive data is acquired by unauthorized users. The approach is to apply redundant attributes to event encryption. The location of links with wire-sniffing in the routing can be inferred by the attributes of leaked data. We show that our approach can effectively improve the system's safety performance without full trust broker-to-broker connections support.
