6 HomeRF Security
Since privacy is a primary concern
for many wireless technology users, HomeRF has vowed to make the
technology as secure as possible.
The first form of security in HomeRF
is a 24-bit network IP that is specific to each personal area network.
This network IP prevents devices outside of a users personal area network
intercepting and using information sent from a remote personal area
network. Take an apartment block as an example, HomeRF devices from one
system could potentially interfere with another apartments HomeRF system.
As well as an independent network
IP, data is sent with a 56-bit encryption algorithm. The 56-bit encryption
algorithm is more tamper proof than the 40-bit encryption codes previously
recommended by the National Security Agency. The encryption algorithm,
which was devised by security experts at Intel, is significantly stronger
than the A5 algorithm used in GSM, yet it is only slightly more complex in
hardware. When exporting HomeRF to countries of concern to the NSA the
encryption algorithm is flexible enough to revert back to 40-bits. SWAP
also makes use of LZRW3-A algorithm when compressing data.
