Understanding Email Encryption Parent topic

Trend Micro Email Encryption encrypts messages using Indentity-Based Encryption (IBE). For example, user1@a.com sends a message with private information to user2@b.com. The domain a.com is registered with IMSVA for encryption and decryption. A policy rule enables outgoing messages containing private information to be encrypted. IMSVA encrypts the message sent to this user2@b.com.
