Short Transitive Signatures for Directed Trees
cryptographic protocols / transitive signatures authenticated data structures collision resistant hashing
2012/3/26
A transitive signature scheme allows to sign a graph in such a way that, given the signature of edges (a,b) and (b,c), it is possible to compute the signature for the edge (or path) (a,c) without the ...
Optimal Data Authentication from Directed Transitive Signatures
cryptographic protocols / transitive signatures authenticated data structures
2012/3/26
An authenticated dictionary of size $N$ is said to be optimal when an update operation or proof computation requires at most $O(\log N)$ accesses to the data-structure, and the size of a proof is $O(1...
We present novel realizations of the transitive signature primitive introduced by Micali and
Rivest [MR02], enlarging the set of assumptions on which this primitive can be based, and also
providing ...
Transitive Signatures Based on Non-adaptive Standard Signatures
Signatures Transitive signatures
2009/3/23
Transitive signature, motivated by signing vertices and edges
of a dynamically growing, transitively closed graph, was first proposed
by Micali and Rivest. The general designing paradigm proposed th...
