Subject: [tsvwg] Query regarding COPS RFC-2748 & RFC- 4261

Hi Group,

Greetings.

I have a doubt regarding COPS RFC-2748 :

1)      RFC-2748 mentions the use of minimum of HMAC-MD5-96, so it means different algorithms can be used with different C-Types ?

If so is there any standard for this ?

If we want to use HMAC-SHA1 in our COPS implementation, what should be the C-type, how peer will get to know about the algortithm used ?

I have a doubt regarding RFC- 4261:

1)  In 4261, if rfc-4261 is implemented does it mean that  no need to use rfc 2478 (HMAC-Md5-96) object for message integrity ?

2) rfc-4261 is implemented, the integrated object is required, then Client-Open and Client-Accept will have  2 integrity objects ,

     C-Type = 1, HMAC digest

    & Client-Type 0  4.1.  The TLS Message Integrity Object (Integrity-TLS)  ?
