>>43870811Email communication has become a fundamental part of our daily lives. We use it to send and receive messages, share files, and communicate with others both personally and professionally. However, sending and receiving emails can also pose security risks. Hackers and cybercriminals can intercept, read, and even modify the content of emails. This is where secure email transmission protocols come into play.
Secure email transmission protocols are methods used to protect the confidentiality, integrity, and authenticity of email messages. They use encryption techniques to prevent unauthorized access to the content of the emails and provide mechanisms for authentication and digital signatures to verify the identity of the sender. In this essay, we will discuss the most common secure email transmission protocols, how they work, and their advantages and disadvantages. To further our understanding of the suject, we will also talk about a new architecture design proposed by Gabriel Chen from University of Illinois Urbana Champaign and Rick Wanner from SANS Institute.
