Abstract

We present an efficient divisible digital cash scheme which is unlinkable and does not require Trusted Third Party. The size of the coin is proportional to the size of the primes we use, i.e., hundreds of bytes. The computational and communication complexity of the protocol is proportional to a polynomial of the size of the primes and polylogarithm of the maximum number of pieces to which a coin can be subdivided.
