The aim of this paper is to introduce some modifications in Tor, in order to improve user\'s anonymity and relay\'s security. Thus, we introduced a system that will ensure anonymity for all users, while

maintaining the ability to break the anonymity of a sender in case of misconduct. The revocation of the anonymity will require the use of secret sharing schemes, since we assume that, the lifting of the

anonymity of the dishonest user should not depend on a single entity, but on a consensus within the network. In addition to the revocation of the anonymity, we propose in this paper further improvements

such as mixing Tor traffic with those of the major internet groups, using the camouflage, or introducing a honeypot in the network.
