A Secure Email Solution Based on Blockchain.
2021
Email is one of the most important online communication services between individuals and businesses. The large amount of information that passes through this medium is the object of desire for many attackers who use a whole series of malicious maneuvers to get hold of it. The number of emails circulating in the world per day is growing, going from 319.6 billion in 2021 to more than 361 billion by the end of 2024. Attackers use all kinds of attacks to participate in these communications, perpetuating attacks that range from spam to very sophisticated attacks such as phishing, scams, among others. There are many solutions available in the market and the email security problem continues to grow and there seems to be no solution in sight. We are working on a different approach. First, we have deeply analyzed the state of the art of email in terms of its design, the security problems identified and the proposed solutions. Subsequently, we have identified the security requirements necessary to address the problem and based on them we have designed an architecture based on a Blockchain platform, whose components interact through different protocols to achieve the objectives proposed in our research.
