+ for a single signature signing 160 bits, this means that
`$\\log t \ge {160-\log k \over k}$`.
- A suitable choise seems to be `$t=1024$`, `$k=24$`

+ - Reyzin pure. Here, we only need the ability to sign 160 bits,

+ `$t=168$`, `$k=69$`
- alternatively, the Reyzin theoretical construction may be used,
where the time spent is somewhat more but security depends
