Revisiting Cryptographic Accumulators, Additional Properties and Relations to other Primitives
static dynamic universal cryptographic accumulators
2016/1/4
Cryptographic accumulators allow to accumulate a finite set of values
into a single succinct accumulator. For every accumulated value, one can
efficiently compute a witness, which certifies its memb...
Cryptographic Accumulators for Authenticated Hash Tables
Cryptographic Accumulators Authenticated Hash Tables
2009/12/29
Hash tables are fundamental data structures that optimally answer membership queries.
Suppose a client stores n elements in a hash table that is outsourced at a remote server. Authenticating the hash...

Batch Update Cryptographic Accumulators
2009/12/29
A cryptographic accumulator is a scheme where a set of elements is represented by a
single short value. This value, along with another value called witness allows to prove
membership into the set. I...
Ensuring Authentication of Digital Information using Cryptographic Accumulators
Stream Authentication Polynomial Reconstruction Erasure Channel Adversarial Channel Cryptographic Accumulator
