+ * GHASH is a keyed hash function used in GCM authentication tag generation.
*
- * The algorithm implementation is copied from gcm.c.
+ * The original GCM paper [1] presents GHASH as a function GHASH(H, A, C) which
+ * takes a 16-byte hash key H, additional authenticated data A, and a ciphertext
+ * C. It formats A and C into a single byte string X, interprets X as a
+ * polynomial over GF(2^128), and evaluates this polynomial at the point H.
+ *
+ * However, the NIST standard for GCM [2] presents GHASH as GHASH(H, X) where X
+ * is the already-formatted byte string containing both A and C.
+ *
+ * "ghash" in the Linux crypto API uses the 'X' (pre-formatted) convention,
+ * since the API supports only a single data stream per hash. Thus, the
+ * formatting of 'A' and 'C' is done in the "gcm" template, not in "ghash".
+ *
+ * The reason "ghash" is separate from "gcm" is to allow "gcm" to use an
+ * accelerated "ghash" when a standalone accelerated "gcm(aes)" is unavailable.
+ * It is generally inappropriate to use "ghash" for other purposes, since it is
+ * an "ε-almost-XOR-universal hash function", not a cryptographic hash function.
+ * It can only be used securely in crypto modes specially designed to use it.
+ *

+ * (http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.694.695&rep=rep1&type=pdf)
