425 * notice 1 (2001 October 5) of [9] (Algorithm 1). As specified in the |
|
426 * change notice (page 74), when Algorithm 1 is used as a general- |
|
427 * purpose random number generator, the "mod q" term in step 3.3 is |
|
428 * omitted. The function G used in the algorithm is constructed via |
|
429 * Secure Hash Standard as specified in Appendix 3.3 of the standard. |
|
430 |
|
431 * 160-bit XKEY and XVAL values are used, so b = 160. The initial |
|
432 * secret seed value XKEY is computed from the n GSM Kc keys and the |
|
433 * NONCE_MT with the following formula: |
|
434 * @code |
|
435 * XKEY = SHA1(n*Kc| NONCE_MT) |
|
436 * |
|
437 * Random generator becomes as follows: |
|
438 * Step 1. Choose a new, secret value for the seed-key, XKEY. |
|
439 * Step 2. In hexadecimal notation let |
|
440 * t = 67452301 EFCDAB89 98BADCFE 10325476 C3D2E1F0. |
|
441 * This is the initial value for H0 || H1 || H2 || H3 || H4 |
|
442 * in the SHS. |
|
443 * Step 3. For j = 0 to m - 1 do |
|
444 * c. xj = G(t,XKEY). |
|
445 * d. XKEY = (1 + XKEY + xj) mod 2^b. |
|
446 * @endcode |
