Signal Game Analysis between Software Vendors and Third-Party Platforms in Collaborative Disclosure of Network Security Vulnerabilities

The global network threat is becoming more and serious, security vulnerability management has become one of the critical areas in national information emergency system construction. To guide third-party sharing platforms regarding management, this work constructs a signal game model comprising software vendors for collaborative disclosures. In addition, we analyze strategy selection its influencing factors. results show that there are two perfect Bayesian equilibria, including separation equilibrium mixed equilibrium, due to incomplete lines disclosure. state mainly based on compression time protection period existence ratio who develop patches market. This puts forward some suggestions terms period, reputation loss, relevant laws regulations.
