BAS: The Biphase Authentication Scheme for Wireless Sensor Networks

Algorithm 1

Key generation algorithm.

Legend:

: Modulo 2 division operation

: Truncates the input stream to 128 bits if 128

KM: Master key of 1024 bits

S: Generator polynomial of 64 bits

: Remainder after division between master key and seed

: Number of bits in remainder

KE: 128 bits Encryption key

Begin Proc

If 128

Else

End Proc
