Internet naming and addressing system security technology and application analysis
Published 2017-03-01“…In order to ensure the security of domain name system and inter-domain routing system,Internet Engineering Task Force(IETF)proposed two kinds of security technology,namely domain name system security extention(DNSSEC)and resource public key infrastructure(RPKI).For the domain name system,DNSSEC added the digital signature to the original architecture of DNS using the public key infrastructure and it provided the authentication and integrity verification of DNS information,which became the anchor of domain name system security.For the inter-domain routing system,RPKI utilized the public key certificate to authenticate the ownership and usage rights of the Internet number resources and builds an Internet resource management system to enhance inter-domain routing security.Recently,the globally development of DNSSEC and RPKI were continuously expanding.In order to research the application of the two kinds of technology,Alexa top 1 million websites were taken as the data set to study and analyze the application status of DNSSEC and RPKI.…”

Account hijacking threat attack detection for OAuth2.0 authorization API
Published 2019-06-01“…OAuth2.0 protocol has been widely adopted to simplify user login to third-party applications,at the same time,existing risk of leaking user privacy data,what even worse,causing user accounts to be hijacked.An account hijacking attack model around authorization code was built by analyzing the vulnerabilities of the OAuth2.0 protocol.A vulnerable API identification method based on differential traffic analysis and an account hijacking verification method based on authorized authentication traffic monitoring was proposed.An account hijacking attack threat detection framework OScan for OAuth2.0 authorization API was designed and implemented.Through a large-scale detection of the 3 853 authorization APIs deployed on the Alexa top 10 000 websites,360 vulnerable APIs were discovered.The further verification showed that 80 websites were found to have threat of account hijacking attack.Compared with similar tools,OScan has significant advantages in covering the number of identity provider,the number of detected relying party,as well as the integrity of risk detection.…”
