Cryptography is an essential means of ensuring security in online communication. Cryptography is a technology that makes data unreadable by replacing it with a series of symbols that are unintelligible to humans, but when we access the data in a communication, it is displayed as data that we can read, so we may rarely encounter a situation where we can intuitively grasp the reality of encryption. As a result, the role that encryption plays is difficult to perceive in comparison to locking the front door of your house, and it is easy to neglect dealing with encryption.
In some cases, data is encrypted on the network, but not on the provider’s server, and in other cases, even the provider cannot read the contents of the communication, and only the sender and the recipient can read it. The latter case is called end-to-end encryption, and is even more desirable for privacy protection.
On the other hand, it is also known that some governments and companies that want to strengthen surveillance of communications are not happy about the fact that we can freely use encryption tools. Governments such as the US, UK, EU and Japan are targeting encryption weaknesses in criminal investigations such as terrorism, child sexual abuse and drug crimes, while governments such as Russia, China and Egypt are taking measures such as banning encryption in order to crack down on anti-government speech.
This seminar will focus on end-to-end encryption, which is becoming increasingly important, and will outline its mechanisms, as well as introduce the moves being made by governments and others to undermine end-to-end encryption.
