Hi All,
What is the need for Null Integrity Protection Algorithm ?

Which of the following does this null encryption or null integrity
algorithm basically refer to ?
1. We will not apply any encryption or integrity protection algorithm.
2. We should tweak encryption algorithm(example - AES-CTR) that will
encrypt such that the text 'S.Man' will get encrypted as 'S.Man' only
or we should tweak integrity algorithm(example - AES-CMAC) to generate
a 32-bit MAC of all zeros repectively.

Thx in advans

Having problems with homework? RFC 2410 is actually quite an
entertaining read. Check it out. http://www.faqs.org/rfcs/rfc2410.html
