A Length-Invariant Hybrid Mix

  title={A Length-Invariant Hybrid Mix},
  author={Miyako Ohkubo and Masayuki Abe},
This paper presents a secure and flexible Mix-net that has the following properties; it efficiently handles long plaintexts that exceed the modulus size of underlying public-key encryption as well as very short ones (length-flexible), input ciphertext length is not impacted by the number of mix-servers (length-invariant), and its security in terms of anonymity is proven in a formal way (provably secure). One can also add robustness i.e. it outputs correct results in the presence of corrupt… CONTINUE READING
