+ * This code derived from a leaked document from the GSM standards.
+ * Some missing pieces were filled in by reverse-engineering a working SIM.
+ * We have verified that this is the correct COMP128 algorithm.
+ *
+ * The first page of the document identifies it as
+ * _Technical Information: GSM System Security Study_.
+ * 10-1617-01, 10th June 1988.
+ * The bottom of the title page is marked
+ * Racal Research Ltd.
+ * Worton Drive, Worton Grange Industrial Estate,
+ * Reading, Berks. RG2 0SB, England.
+ * Telephone: Reading (0734) 868601 Telex: 847152
+ * The relevant bits are in Part I, Section 20 (pages 66--67). Enjoy!
+ *
+ * Note: There are three typos in the spec (discovered by
+ * reverse-engineering).
+ * First, "z = (2 * x[n] + x[n]) mod 2^(9-j)" should clearly read
+ * "z = (2 * x[m] + x[n]) mod 2^(9-j)".
+ * Second, the "k" loop in the "Form bits from bytes" section is severely
+ * botched: the k index should run only from 0 to 3, and clearly the range
+ * on "the (8-k)th bit of byte j" is also off (should be 0..7, not 1..8,
+ * to be consistent with the subsequent section).
+ * Third, SRES is taken from the first 8 nibbles of x[], not the last 8 as
+ * claimed in the document. (And the document doesn't specify how Kc is
+ * derived, but that was also easily discovered with reverse engineering.)
+ * All of these typos have been corrected in the following code.
