Why is EaSecure more secure than Identity Based Encryption (IBE)?
Another type of system that has the potential to achieve “Send to Anyone” is the Identity Based Encryption (IBE) system. In such a system, the identity of the recipient can be directly used to encrypt the message. In other words, the recipient’s “public key” can simply be the email address of the recipient. In this way, every email address already has a “public key,” and therefore, encrypted messages can be sent to anyone who has an email address. The problem with such a system, however, is that it relies on a “Master Secret” stored on a central server to issue everybody’s private key. In other words, the central server knows everybody’s private key and has the ability to decrypt every message. For this reason, IBE is categorically less secure than the standard public-key encryption. EaSecure is different. The recipient is automatically turned into a user of standard public-key encryption after opening just one message using a one-time password. No “Master Secret” exists that can deriv
