Whether the digital 1102 certificate of the first node is valid is verified with the second node based on the first communication request and certificate validity information, where the certificate validity information is stored in the blockchain and is used to reflect validity status information of a digital certificate of a node, when the digital certificate of the first node is valid, whether to establish a communication con- nection to the first node is determined by the second node. 1104 Bitirectional 1108 Unntethonal notattsdng a arnrnun eaten connedon etttoen toe second ncdo and the first node ed certficate va hit invmm,an,ehethert,e 1,- -1116 Access ng, by thedr node hesedon the RDA cornundahon request QOM...Ally Infornato °dated vdth nn ,nen I 1114 nodes in he oloucha n \"\" fr e7d i nVolTfin d Zo l 4 a e ' s ' ectt n nt ' ar\" d erdn ' re droo r tnted neN ' f h the e e n ' ot=t e ll neltXtn d\"\" [ 1112 FIG. 11 W O 20 19/0 23 47 0 Al Von , \" thud node °`\"' \"Ii;;Vern m esa i (12) INTERNATIONAL APPLICATION PUBLISHED UNDER THE PATENT COOPERATION TREATY (PCT) (19) World Intellectual Property Organization International Bureau (43) International Publication Date 31 January 2019 (31.01.2019) WIPO I PCT omit omoimilmomoilowo oimIE (10) International Publication Number WO 2019/023470 Al (51) International Patent Classification: GOOF 21/64 (2013.01) G06Q 20/06 (2012.01) H04L 29/06 (2006.01) (21) International Application Number: PCT/US2018/043919 (22) International Filing Date: 26 July 2018 (26.07.2018) (25) Filing Language: English (26) Publication Language: English (30) Priority Data: 201710617599.7 26 July 2017 (26.07.2017) CN (71) Applicant: ALIBABA GROUP HOLDING LIMITED [ /US]; Fourth Floor, One Capital Place, P.O.
