International security competition and debates on state sovereignty in the cyberspace and suggest plausible means

Cyber security has long been the focus of international competition, may it be in political and economic theft or military confrontation. The lack of related legal norms and the inability to identify actual network actors led to constant frictions in the cyber security filed in the short-run. To deal with emerging issues of Internet sovereignty in the cyberspace, and base on the spirit of flag state jurisdiction under UNCLOS, this paper proposed to institute a digital network certification system, which provide Internet user to authenticate his/her nationality through systematic practices as a viable solution to settle future international conflicts in the cyberspace.
