....network bandwidth. The required CPU time is determined by the speed of the MACs. Each MAC can be prodcued and verified by hashing over the message contents, and then hashing over the concatenation of that hash with the MAC key. Thus, two hashes are used. The speed of the SHA 1 hash was measured in [19] as ) ms on a , MHz machine. If we extraploate to a GHz speed, this number becomes )#) C, ms. Thus, a MAC takes ) 0 , ms to produce and to verify. Using this number, the required CPU time in this scheme for cryptography is g # 4 )#h MAC node second A ....
