Encypted Vs Protected Channel

[akiba201]

hi there,

does anyone out there know the difference between encrypted and protected channel?

is SSL an encrypted or protected channel?

thanks.

SSL is an encrypted channel. An example of a protected channel (according to the books but not experience) would be a point to point link. It's protected from everyone except point a and point b.

Think of encrypted for what it is... Encrypted. Protected for what it is protected. You encrypted something with standard DES is it protected? No. You encrypt something with DES on point a and send it to point b is it protected? Yes to some degree.

perl -e 'print $i=pack(c5,(40*2),sqrt(7600),(unpack(c,Q)-3+1+3+3-7),oct(104),10,oct(101));'

You may have a point-to-point dedicated circuit with a firewall at either end, that would also be protected, but not encrypted.

Also, an ipsec packet using authentication header is digitally signed, but not encrypted. It is protected though.

Lastly, GRE is protected by traffic being hidden but not necessarily encrypted.

It's basic pedantry ; )
