The origional FIPE 180 used SHA-0 (FIPS 180) for its appendix 5
|
||
|
|
examples. This is an updated version that uses SHA-1 (FIPS 180-1)

APPENDIX 5. EXAMPLE OF THE DSA
|
||
|
|
|
||
|
|
|
||
|
|
This appendix is for informational purposes only and is not required to meet
|
||
|
|
the standard.
|
||
|
|
|
||
|
|
Let L = 512 (size of p). The values in this example are expressed in
|
||
|
|
hexadecimal notation. The p and q given here were generated by the prime
|
||
|
|
generation standard described in appendix 2 using the 160-bit SEED:
|
||
|
|
|
||
|
|
d5014e4b 60ef2ba8 b6211b40 62ba3224 e0427dd3
|
||
|
|
|
||
|
|
With this SEED, the algorithm found p and q when the counter was at 105.
|
||
|
|
|
||
|
|
x was generated by the algorithm described in appendix 3, section 3.1, using
|
||
|
|
the SHA to construct G (as in appendix 3, section 3.3) and a 160-bit XSEED:
|
||
|
|
|
||
|
|
XSEED =
|
||
|
|
|
||
|
|
bd029bbe 7f51960b cf9edb2b 61f06f0f eb5a38b6
|
||
|
|
|
||
|
|
t =
|
||
|
|
67452301 EFCDAB89 98BADCFE 10325476 C3D2E1F0
|
||
|
|
|
||
|
|
x = G(t,XSEED) mod q
|
||
|
|
|
||
|
|
k was generated by the algorithm described in appendix 3, section 3.2, using
|
||
|
|
the SHA to construct G (as in appendix 3, section 3.3) and a 160-bit KSEED:
|
||
|
|
|
||
|
|
KSEED =
|
||
|
|
|
||
|
|
687a66d9 0648f993 867e121f 4ddf9ddb 01205584

|
||
|
|
|
||
|
|
k = G(t,KSEED) mod q
|
||
|
