Appendix A. Pseudo-Random Number Generator
The "|" character denotes concatenation, and "^" denotes
exponentiation.
Step 1: Choose a new, secret value for the seed-key, XKEY
Step 2: In hexadecimal notation let
t = 67452301 EFCDAB89 98BADCFE 10325476 C3D2E1F0
This is the initial value for H0|H1|H2|H3|H4
in the FIPS SHS [SHA-1]
Step 3: For j = 0 to m - 1 do
3.1. XSEED_j = 0 /* no optional user input */
3.2. For i = 0 to 1 do
a. XVAL = (XKEY + XSEED_j) mod 2^b
b. w_i = G(t, XVAL)
c. XKEY = (1 + XKEY + w_i) mod 2^b
3.3. x_j = w_0|w_1
