The　conventional　ring　signature　schemes　cannot　address　the　scenario　where　the　rank　of　members　of　the　ring　needs　to　be　distinguished,　for　example,　in　electronically　commerce　application.　To　solve　this　problem,　we　presented　a　Trusted　Platform　Module　(TPM)-based　threshold　ring　signature　scheme.　Employing　a　reliable　secret　Share　Distribution　Center　(SDC),　the　proposed　approach　can　authenticate　the　TPM-based　identity　rank　of　members　of　the　ring　but　not　track　a　specific　member＇s　identity.　A　subset　including　t　members　with　the　same　identity　rank　is　built.　With　the　signing　cooperation　of　t　members　of　the　subset,　the　ring　signature　based　on　Chinese　remainder　theorem　is　generated.　We　proved　the　anonymity　and　unforgeability　of　the　proposed　scheme　and　compared　it　with　the　threshold　ring　signature　based　on　Lagrange　interpolation　polynomial.　Our　scheme　is　relatively　simpler　to　calculate.
