EMCSSL: Blockchain application for network security This security system is high scalable, and provides complete 3-in-1 functionality: 1 - verify server identity 2 - verify client identity 3 - establish encrypted secure connection The novelty of the proposal is in the complete decentralization of the system, i.e. the lack of a group of servers running under a single authorization (as used in the systems of Kerberos, OpenID, TeddyID and the like). As a result, it is not possible for EMCSSL to suffer system-wide service disruption either due to technical failure or malicious attack upon authorization servers. In addition, it is not possible for a user to have their accounts globally suspended at the whim of a single authority.
