Voltage Security has developed a new means of encrypting email communications that does not rely on the PKI (public-key infrastructure) commonly used in other encryption schemes. End-users, especially non-technical users, have difficulty understanding and successfully implementing PKI. Voltage Security's encryption technology promises to be much easier to set up and use.
It encrypts using an algorithm based on the email address of the sender. To learn more about it check out the article here: Start-up To Unveil New Way of Encryption
