A severe weakness of the onion protocol, one of the major tools for anonymous relationship, is its vulnerability to system failures and/or an adversary trying to break the communication. This is facilitated by the truth that each message is sent by way of a path of a specific length and a failure inside a point of this path prohibits message delivery. Because the path cannot be too short to offer anonymity protection (at least logarithmic in the amount of nodes), the failure probability might be quite substantial. The simplest solution to this issue is usually to send many onions with the same message. We show that method can be optimized with respect to interaction hydra tor overhead and resilience to failures and/or adversary episodes. We propose two protocols: the first one mimics K independent onions with an individual onion. The next protocol is designed for the circumstance where an adaptive…
