What types of AVPs are encrypted in a diameter message ?

Question

What are the encrypted AVPs and significance of these. How encryption is enabled between the two diameter nodes ? Is there any separate message to enable encryption between the nodes ?

Answer 1

Hi Harshita,

From RFC-3588 I found a statement which mention "The 'P' bit indicates the need for encryption for end-to-end security".
Where P - Protected Bit in AVP Flags.
Also section 4.5 Listed the AVPs which will be considered for Encryption.

Please refer two columns one is MAY which is under AVP Flag Rules which listed the AVPs with ''P'' Bit and last column of the table which is not part of the AVP Flag Rules which marked as "Encr".

I hope that is what you are looking for.

Note:- Same informations are not available in RFC-6733 which are mention in the same section of RFC-3588

Thanks
