Hash-based data structures for secure logging and other applications
This talk considers two different kinds of data structures built primarily from hash functions. Almost any data structure from the world of functional programming can be turned into a hash data structure, where a pointer includes the hash of the thing it points to. This has enabled all sorts of clever applications, where data can be stored on an untrusted server and the hash structures will allow any tampering to be discovered. In particular, we will discuss efficient techniques for tamper-evident logging and for persistent authenticated dictionaries.
