++ SipHash - a short input PRF |
45 |
++----------------------------------------------- |
46 |
++Written by Jason A. Donenfeld <jason@×××××.com> |
47 |
++ |
48 |
++SipHash is a cryptographically secure PRF -- a keyed hash function -- that |
49 |
++performs very well for short inputs, hence the name. It was designed by |
50 |
++cryptographers Daniel J. Bernstein and Jean-Philippe Aumasson. It is intended |
51 |
++as a replacement for some uses of: `jhash`, `md5_transform`, `sha_transform`, |
52 |
++and so forth. |
53 |
++ |
54 |
++SipHash takes a secret key filled with randomly generated numbers and either |
55 |
++an input buffer or several input integers. It spits out an integer that is |
56 |
++indistinguishable from random. You may then use that integer as part of secure |
57 |
++sequence numbers, secure cookies, or mask it off for use in a hash table. |
58 |
++ |
59 |
++1. Generating a key |
60 |
++ |
61 |
++Keys should always be generated from a cryptographically secure source of |
62 |
++random numbers, either using get_random_bytes or get_random_once: |
63 |
++ |
64 |
++siphash_key_t key; |
65 |
++get_random_bytes(&key, sizeof(key)); |
66 |
++ |
67 |
++If you're not deriving your key from here, you're doing it wrong. |
68 |
++ |
69 |
++2. Using the functions |
70 |
++ |
71 |
++There are two variants of the function, one that takes a list of integers, and |
72 |
++one that takes a buffer: |
73 |
++ |
74 |
++u64 siphash(const void *data, size_t len, const siphash_key_t *key); |
75 |
++ |
76 |
++And: |
77 |
++ |
78 |
++u64 siphash_1u64(u64, const siphash_key_t *key); |
79 |
++u64 siphash_2u64(u64, u64, const siphash_key_t *key); |
80 |
++u64 siphash_3u64(u64, u64, u64, const siphash_key_t *key); |
81 |
++u64 siphash_4u64(u64, u64, u64, u64, const siphash_key_t *key); |
82 |
++u64 siphash_1u32(u32, const siphash_key_t *key); |
83 |
++u64 siphash_2u32(u32, u32, const siphash_key_t *key); |
84 |
++u64 siphash_3u32(u32, u32, u32, const siphash_key_t *key); |
85 |
++u64 siphash_4u32(u32, u32, u32, u32, const siphash_key_t *key); |
86 |
++ |
87 |
++If you pass the generic siphash function something of a constant length, it |
88 |
++will constant fold at compile-time and automatically choose one of the |
89 |
++optimized functions. |
90 |
++ |
91 |
++3. Hashtable key function usage: |
92 |
++ |
93 |
++struct some_hashtable { |
94 |
++ DECLARE_HASHTABLE(hashtable, 8); |
95 |
++ siphash_key_t key; |
96 |
++}; |
97 |
++ |
98 |
++void init_hashtable(struct some_hashtable *table) |
99 |
++{ |
100 |
++ get_random_bytes(&table->key, sizeof(table->key)); |
101 |
++} |
102 |
++ |
103 |
++static inline hlist_head *some_hashtable_bucket(struct some_hashtable *table, struct interesting_input *input) |
104 |
++{ |
105 |
++ return &table->hashtable[siphash(input, sizeof(*input), &table->key) & (HASH_SIZE(table->hashtable) - 1)]; |
106 |
++} |
107 |
++ |
108 |
++You may then iterate like usual over the returned hash bucket. |
109 |
++ |
110 |
++4. Security |
111 |
++ |
112 |
++SipHash has a very high security margin, with its 128-bit key. So long as the |
113 |
++key is kept secret, it is impossible for an attacker to guess the outputs of |
114 |
++the function, even if being able to observe many outputs, since 2^128 outputs |
115 |
++is significant. |
116 |
++ |
117 |
++Linux implements the "2-4" variant of SipHash. |
118 |
++ |
119 |
++5. Struct-passing Pitfalls |
120 |
++ |
121 |
++Often times the XuY functions will not be large enough, and instead you'll |
122 |
++want to pass a pre-filled struct to siphash. When doing this, it's important |
123 |
++to always ensure the struct has no padding holes. The easiest way to do this |
124 |
++is to simply arrange the members of the struct in descending order of size, |
125 |
++and to use offsetendof() instead of sizeof() for getting the size. For |
126 |
++performance reasons, if possible, it's probably a good thing to align the |
127 |
++struct to the right boundary. Here's an example: |
128 |
++ |
129 |
++const struct { |
130 |
++ struct in6_addr saddr; |
131 |
++ u32 counter; |
132 |
++ u16 dport; |
133 |
++} __aligned(SIPHASH_ALIGNMENT) combined = { |
134 |
++ .saddr = *(struct in6_addr *)saddr, |
135 |
++ .counter = counter, |
136 |
++ .dport = dport |
137 |
++}; |
138 |
++u64 h = siphash(&combined, offsetofend(typeof(combined), dport), &secret); |
139 |
++ |
140 |
++6. Resources |

++HalfSipHash - SipHash's insecure younger cousin |
149 |
++----------------------------------------------- |
150 |
++Written by Jason A. Donenfeld <jason@×××××.com> |
151 |
++ |
152 |
++On the off-chance that SipHash is not fast enough for your needs, you might be |
153 |
++able to justify using HalfSipHash, a terrifying but potentially useful |
154 |
++possibility. HalfSipHash cuts SipHash's rounds down from "2-4" to "1-3" and, |
155 |
++even scarier, uses an easily brute-forcable 64-bit key (with a 32-bit output) |
156 |
++instead of SipHash's 128-bit key. However, this may appeal to some |
157 |
++high-performance `jhash` users. |
158 |
++ |
159 |
++Danger! |
160 |
++ |
161 |
++Do not ever use HalfSipHash except for as a hashtable key function, and only |
162 |
++then when you can be absolutely certain that the outputs will never be |
163 |
++transmitted out of the kernel. This is only remotely useful over `jhash` as a |
164 |
++means of mitigating hashtable flooding denial of service attacks. |
165 |
++ |
166 |
++1. Generating a key |
167 |
++ |
168 |
++Keys should always be generated from a cryptographically secure source of |
169 |
++random numbers, either using get_random_bytes or get_random_once: |
170 |
++ |
171 |
++hsiphash_key_t key; |
172 |
++get_random_bytes(&key, sizeof(key)); |
173 |
++ |
174 |
++If you're not deriving your key from here, you're doing it wrong. |
175 |
++ |
176 |
++2. Using the functions |
177 |
++ |
178 |
++There are two variants of the function, one that takes a list of integers, and |
179 |
++one that takes a buffer: |
180 |
++ |
181 |
++u32 hsiphash(const void *data, size_t len, const hsiphash_key_t *key); |
182 |
++ |
183 |
++And: |
184 |
++ |
185 |
++u32 hsiphash_1u32(u32, const hsiphash_key_t *key); |
186 |
++u32 hsiphash_2u32(u32, u32, const hsiphash_key_t *key); |
187 |
++u32 hsiphash_3u32(u32, u32, u32, const hsiphash_key_t *key); |
188 |
++u32 hsiphash_4u32(u32, u32, u32, u32, const hsiphash_key_t *key); |
189 |
++ |
190 |
++If you pass the generic hsiphash function something of a constant length, it |
191 |
++will constant fold at compile-time and automatically choose one of the |
192 |
++optimized functions. |
193 |
++ |
194 |
++3. Hashtable key function usage: |
195 |
++ |
196 |
++struct some_hashtable { |
197 |
++ DECLARE_HASHTABLE(hashtable, 8); |
198 |
++ hsiphash_key_t key; |
199 |
++}; |
200 |
++ |
201 |
++void init_hashtable(struct some_hashtable *table) |
202 |
++{ |
203 |
++ get_random_bytes(&table->key, sizeof(table->key)); |
204 |
++} |
205 |
++ |
206 |
++static inline hlist_head *some_hashtable_bucket(struct some_hashtable *table, struct interesting_input *input) |
207 |
++{ |
208 |
++ return &table->hashtable[hsiphash(input, sizeof(*input), &table->key) & (HASH_SIZE(table->hashtable) - 1)]; |
209 |
++} |
210 |
++ |
211 |
++You may then iterate like usual over the returned hash bucket. |
212 |
++ |
213 |
++4. Performance |
214 |
++ |
215 |
++HalfSipHash is roughly 3 times slower than JenkinsHash. For many replacements, |
216 |
++this will not be a problem, as the hashtable lookup isn't the bottleneck. And |
217 |
++in general, this is probably a good sacrifice to make for the security and DoS |
218 |
++resistance of HalfSipHash. |
