Hi Margaret, 

 

I pointed this out in my review here:

https://mailarchive.ietf.org/arch/msg/radext/Rnh9mBSC_n87-c6yUrCpakVu_B0/

 

Ciao

Hannes

Subject: [radext] Selfie Attack on TLS-PSK

 

On a separate but related note…. 

 

I came across this attack while reading about TLS mutual authentication:

 






 <https://eprint.iacr.org/2019/347.pdf> 347

 <https://eprint.iacr.org/2019/347.pdf> PDF Document · 1.2 MB

 

 

Is this something we should consider before we recommend the use of TLS-PSK with TLS 1.3? Or has this issues already been addressed?

 

Thanks,

Margaret
