Chaos-based broadcast encryption with authenticated secure message transmission scheme

Abstract

In scenarios requiring high security and frequent data exchange, such as multi-agent intelligence gathering, researchers are primarily concerned with ensuring robust security measures. While encryption methods are currently employed for data protection, there is a notable lack of research focusing on secure data transmission. Consequently, there is an immediate necessity for an information transmission architecture that is anonymous, tamper-proof, and untraceable, in order to bolster the security of data itself and data exchange. To address this need, this paper proposes Chaos-based Broadcast Encryption with Authenticated Secure Message Transmission scheme (CBENAU). The proposed method devises a secure broadcast encryption algorithm founded on chaos theory, which effectively encrypts messages and dispatches them to multiple authorized recipients. This approach ensures both data protection and a reduction in communication overhead associated with message transmission. Furthermore, the inclusion of content publisher authentication serves as a deterrent against spam dissemination in broadcast encryption systems. A relay transmission network is constructed for message transmission to ensure the untraceability of senders and recipients. Through rigorous security analysis, the proposed CBENAU scheme demonstrates its resilience against ciphertext attacks, surpassing the security levels provided by traditional RSA and ElGamal. Moreover, the scheme is anonymity, public verifiability, confidentiality, and non-repudiation.
