1. Email needs the popular application of encryption technology urgently

From the birth of the first email marked with the @ symbol in 1971, to 2021, the 50-year-old email is the first and most widely used Internet application. According to statistics, there are 3.7 billion email accounts in the world and there are 269 billion emails sent every day. In other words: Email is a must for work and life.

The email system is a distributed and decentralized messaging system that covers all corners of the world. It is also the world’s largest and most popular Internet service infrastructure. Anyone can get a free email account and email communication service at any time, and both free email service and paid service have achieved with unlimited email storage capacity. People are enjoying this convenient email service that has been developed for 50 years, and it is inseparable from email service (even the social media is hot now).

Email peer-to-peer communication is a decentralized service that can best protect user privacy; while instant messaging (chat) and social media can be considered as a Web application, a highly centralized and oligopolistic monopoly service. In the context of increasing demand for decentralization and privacy protection, we believe that encrypted email will play a greater role and bring more convenience and happiness to mankind.

However, as an "old" technology, email was sent in cleartext when it was originally designed, and it was a "postcard". This is in the already-developed high-speed Internet and mobile Internet 5G era, especially in the era of cloud computing and big data that this “design defect” is already a big security issue. The second application of the Internet, WWW browsing, was also transmitted in HTTP cleartext when it was originally designed, but after more than ten years of industry efforts, it has been gradually upgraded to https encrypted transmission.

Before specifically introducing MeSign Technology solutions, let us briefly introduce cloud computing. Cloud computing is the delivery of computing services (including servers, storage, databases, networks, software, analysis and intelligence)-over the Internet to offer fast innovation, flexible resources and economies of scale. For cloud services, you typically pay only for cloud services you use, helping you lower your operating costs, run your infrastructure more efficiently, and scale as your business needs change. Cloud computing has seven advantages as low cost (pay on demand), fast deployment and high efficiency (buy as needed), good scale (flexible expansion at any time on demand), and high performance (purchase required computing power on demand, without performance bottlenecks) ), high reliability (to ensure business continuity), high security (professional security protection), making cloud computing and cloud services have become the current standard configuration of all Internet services and the first choice for enterprise production and operation. As far as email services are concerned, according to incomplete statistics, 86% of the global top 500 companies have migrated their own email services to cloud email services, while 100% of small and medium-sized enterprises and individuals use cloud email service.

The advantages of cloud services are recognized, but cloud computing and big data have brought about a problem of data security and privacy protection. As far as email services are concerned, emails contain a large amount of personal privacy, personal confidential information, and business confidential information. In addition to the security risks of cleartext transmission, these information also face a possible leakage of confidential information stored in the cloud in cleartext. In the era of self-management of mail servers, mail servers are generally located in the company’s intranet, the network access controls, and security controls can ensure the security of mail content stored on the mail server, but now the email content is stored in the cloud. Although the cloud email service provider has very complete security control, but it is no longer under the user's own control. How to ensure that the email content will not be illegally stolen and illegally leaked is also an urgent problem to be solved.

Therefore, in order to solve the problem of email security, it is necessary to solve both the security problems of email transmission and email storage. In fact, these two problems can be solved with one technology at the same time, that is, end-to-end encryption. The email is encrypted into cipher text when it is sent, which solves the problem that the content of the email is easily stolen and illegally tampered due to the transmission of clear text during transmission. After the email reaches the recipient’s email server, since the email itself is already in cipher text, it can be directly stored in the cloud mail server, which also solves the security problem of email storage.

2. MeSign email encryption and digital signature technology application innovation

An Apple technical expert wrote in an email discussion group on email security: "Email as a tool for the betterment of humankind has proven so effective as to be arguably invaluable; improving the security, privacy, and safety of using email is a very worthwhile goal.” This sentence is very good, with two important points: one is to highly affirm the contribution of email to improving human life, and to affirm that this communication method is efficient; the other is to point out the security of email still need to improve and enhance.

How to improve and enhance the security of email, MeSign Technology provides a perfect solution-based on cloud computing and cryptographic technology to fully realize end-to-end email encryption and digital signature, which completely solves the problem of security and confidentiality of email content. It will rejuvenate the "old" email and provide more secure email communication services for mankind.

We believe that people need cloud services, but in order to protect user privacy and business secrets, people can’t just rely on cloud services. People need some key data to be stored locally on their computers, and some key data operations are done locally on their computers. Only in this way can we effectively use the powerful cloud computing capabilities and cloud services to achieve previously impossible functions, and can we use client software to complete key operations and key data management locally. This is the most perfect solution-"Cloud-Client integration, collaborative work", this is the integrated application of cloud services and client software, and the future development direction of cloud computing and client software. And this is the core of our solution.

There is no doubt that PKI technology (Public Key Infrastructure) is the only reliable technology to guarantee the security of the Internet, which completely solves the four headache data security issues (PAIN): (1) the confidentiality of data (Privacy); (2) the identity authenticity of the data producer and user (Authentication); (3) data integrity (Integrity); (4) non-repudiation of data generation and usage behavior (Non-repudiation). The important application of PKI technology is the application of digital certificate, but it is undeniable that how to use digital certificate easily is also a headache.

MeSign Technology is committed to email encryption and digital signature applications, giving full play to the CA genes and Internet security genes of the R&D team, making full use of cloud computing technology and cloud computing infrastructure, and successfully developing encrypted email client software-MeSign App, cloud and client work together to make the complicated encryption and digital signature of email communication are completely fully automated, and the zero threshold and complete insensitivity, and make the complex PKI encryption technology truly popularized and applied! Users do not need to learn and train what is a digital certificate, nor do they need to apply for a digital certificate from CA, and learnt to deploy and use the certificate, our solutions realize certificate automatic application and automatic deployment, so that users only need to focus on using the software system to serve their business.
