Abstract: DC-Nets can be considered as an important solution to anonymous communications. However, their high message and bit complexity is a major obstacle in their practical use. All DC-Net protocols provide anonymity of both sender and receiver by establishing some anonymous channels for message transmission. We propose a new DC-Net protocol that allows n simultaneous anonymous channels with the same message and bit complexity as the original DC-Net protocol. So, we reduced the bit complexity of DC-Nets by O (n). We prove the anonymity of our protocol and show that it is susceptible to some attacks similar to possible attacks against standard DC-Net protocols. Some existing methods of protecting DC-Nets from adversaries are extended to protect our protocols against possible attacks.
