Time Stamp: tsa field in TSTInfo



    Hi everybody!
 
    I am involved in a Time Stamping project and we are analysing the PKIX draft about this subject.
 
    I would like to give my opinion on an issue to the list:
    It seems not appropriate to include a field in TSTInfo structure related to the tsa identity, i.e. tsa field. I don't find this field necessary because it is repeated when using a CMS or PKCS#7 envelope to encapsulate the token information. This information would be redundant since an identifier distinguishing the given tsa should be present in the signerInfo structure.
 
    So, I recommend the deletion of this field.
 
    Regards,
   Juan Luis López
