IEC 62351-3-2018 pdf free.Power systems management and associated information exchange – Data and communications security – Part 3: Communication network and system security- Profiles including TCP/IP.
This part of lEC 62351 specifies how to secure TCP/IP-based protocols through constraintson the specification of the messages, procedures,and algorithms of Transport Layer Security(TLS)(defined in RFC 5246) so that they are applicable to the telecontrol environment of theiEC. TLS is applied to protect the TCP communication. It is intended that this standard bereferenced as a normative part of other lEC standards that have the need for providingsecurity for their TCP/IP-based protocol.However, it is up to the individual protocol securityinitiatives to decide if this standard is to be referenced.
This part of lEC 62351 reflects the security requirements of the lEC power systemsmanagement protocols.Should other standards bring forward new requirements, this standardmay need to be revised.
1.2lntended Audience
The initial audience for this specification is intended to be experts developing or making useof lEC protocols in the field of power systems management and associated informationexchange. For the measures described in this specification to take effect，they must beaccepted and referenced by the specifications for the protocols themselves,where theprotocols make use of TCP/IP security.This document is written to enable that process.
The subsequent audience for this specification is intended to be the developers of productsthat implement these protocols.
Portions of this specification may also be of use to managers and executives in order tounderstand the purpose and requirements of the work.

4.1 Operational requirements affecting the use of TLS in the telecontrol environmentThe lEC telecontrol environment has different operational requirements from manyInformation Technology (IT) applications that make use of TLS in order to provide securityprotection. The most differentiating, in terms of security， is the duration of the TCP/IPconnection for which security needs to be maintained.
Many IT protocols have short duration connections，which allow the encryption algorithms tobe renegotiated at connection re-establishment. However, the connections within a telecontrolenvironment tend to have longer durations，often“permanent”. lt is the longevity of theconnections in the field of power systems management and associated information exchangethat give rise to the need for special consideration. ln this regard，in order to provideprotection for the “permanent”connections，a mechanism for updating the session’ key isspecified within this standard,based upon the TLS features of session resumption andsession re-negotiation while also considering the relationship with certificate revocation stateinformation.IEC 62351-3 pdf download,
