About Direct Secure Messaging
Direct Secure Messaging, commonly referred to as Direct, is a secure communication transport mechanism for sensitive information over the open internet. While appearing like email, Direct Secure Messaging utilizes digital certificates and a Public Key Infrastructure (PKI) to encrypt the contents of a message, meaning only the intended recipient can decrypt the message. Today, Direct Secure Messaging utilizes the foundation of the Direct Standard™, and is a widely deployed and accessible means for communicating sensitive health information to other trusted parties. Considered a “push” interoperability mechanism because of the sender “pushing” a message to the receiver, Direct Secure Messaging is a cornerstone of facilitating interoperability between disparate health technologies and organizations.
