Hi
This is probably a stupid question, but there's something I don¹t
understand in section 5.3.2:
keyName-NAI: This is carried in a TLV payload. The Type is 1.
The NAI is variable in length, not exceeding 253 octets. The
EMSKname is in the username part of the NAI and is encoded in
hexadecimal values. The EMSKname is 64 bits in length and so
the username portion takes up 128 octets.
If EMSKname is 64 bits, why does it take 128 hexadecimal octets to encode
it? Either it's 16 hexadecimal octets, or the EMSKname is actually 64
bytes, rather than bits.
What am I missing?
Yoav
