    Is the MAC depends on the content of provisioning/bootstrap document?

    I have tried the OMA example successsully. However, after I change some of the parameters, the PIN 1234 does not work for that MAC. Can anyone tell me the possible error or how should I change the MAC ?

    Yes,
    if the content is modified MAC need recalculation.
    Please read page 12 ProvBoot , 2nd paragraph.

    Thanks~

    But when I read through the related documents. It [WTLS] said that the byte length of Hash output is 20 for SHA-1. Why the example in OMA ProvCont is 40 bytes instead of 20 bytes?
