Privex: A Privacy-Preserving Online Meeting System Using Hybrid Cryptography

Abstract

In this paper, a behaviour-sensitive session orchestration architecture over secure communication and the rationale behind it will be proposed and discussed, which is a variant of mixed public-key cryptography that aims at offering more manageable, secret, and authenticity in real-time messaging infrastructure. The architecture incorporates the use of RSA and Diffie Hellman in ensuring the setup of user sessions and relies on AES to encrypt instantaneous messages very quickly. Multi-fernet algorithm supports the distribution of session keys and ensures that the key is recovered by the authorized parties only. There are also digital signatures based on RSA that facilitate authentication and non-repudiation but strong hash algorithms are applied to ensure the privacy of user passwords. The system has collaborative features along with cryptographic protection, including co-host delegation, active user blocking, permissions and multi-session to support multi-user logins. Also, the design enables the dynamically updating of the authentication credentials without disruption of the existing communication. The suggested hybrid configuration has a higher level of defense against cryptographic attacks and unauthorized access than single algorithm implementations, which is why it is a more robust and secure solution. In conclusion, the provided solution contributes to the fact that the process of communication in the environment of multi-users becomes much safer, convenient, and manageable.
