Abstract

In the context of the Internet and network, secure data exchange along with the anonymity of sender and receiver has been one of the main needs of users. Therefore, various types of anonymity networks have been designed and developed. The architecture of the anonymity network and the structural weakness of the encryption system used in them have caused numerous security problems. with the advancement of quantum computing, many attacks have been designed and successfully disrupted the security of the anonymity network. Various mechanisms have been proposed to improve the security of anonymous networks, some of which are only theoretical and cannot be implemented, and others have serious weaknesses and vulnerabilities that cannot be used. The breaking of Encryption systems, the vulnerability of classic digital signatures, and non-resistant cryptographic algorithms against quantum attacks are among the important weaknesses of the architecture of anonymous networks. To overcome these challenges, a secure structure using a QMNTR encryption system and LRS digital signature based on the onion routing structure has been proposed to secure the anonymous network. The results of Research and technical evaluation show that the proposed architectural structure improves the ability to deal with all kinds of threats and ensures the reliability of relays in the anonymity network. In addition, with appropriate time complexity, the security of key distribution has increased and the communication overhead has been reduced. Using an LRS digital signature has also helped improve the anonymous network's security and has achieved acceptable performance.
