128-bit tags (experimental)
|
|
||||||
---------------------------
|
|
||||||
|
|
||||||
In addition to the original SipHash, which returns 64-bit tags, this
|
## Intellectual property
|
||||||
reference code implements an experimental mode to return 128-bit tags.
|
|
||||||
This mode is enabled when the constant `DOUBLE` is defined.
|
|
||||||
|
|
||||||
Running
|
|
||||||
|
|
||||||
```sh
|
|
||||||
make double
|
|
||||||
```
|
|
||||||
|
|
||||||
will build `siphash24_test_double` and `siphash24_debug_double`.
|
|
||||||
|
|
||||||
SipHash with 128-bit tags targets PRF security with 128-bit key and
|
|
||||||
128-bit tags. In particular, any attack trying up to 2^s should
|
|
||||||
succeed with probability at most 2^(s - 128).
|
|
||||||
|
|
||||||
The **128-bit mode is experimental**, use at your own risk.
