IEC TC 57 just published the document 57/1939/DTR:

Data and communications security –
IEC TR 62351-90-2: Deep Packet Inspection (DPI) of encrypted communications
This technical report analyses the impact of encrypted communication channels in power systems introduced with IEC 62351. As defined in IEC 62351 an encrypted channel can be employed when communicating with IEDs and encryption can be adopted at message level as well. For example, the use of encrypting TLS setups according to IEC 62351-3 introduces some issues when Deep Packet Inspection (DPI) is needed to inspect the communication channel for monitoring, auditing and validation needs.
In this report we analyze different techniques that can be employed to circumvent this issues when DPI of communications is required.
