Abstract: The digital substation will be the essential tendency of substations development. And the information security and its safeguard will become a hot spot. Based on the analysis of the ethernet of digital substation, the security meaning and threats of digital substation information were discussed. Some security strategies and measures were proposed, such as digital signature、VLAN、multiagent and firewall.
Key words: digital substation; digital signature; virtual local area network (VLAN); multiagent
