This is identity based encryption, I've heard about it. http://www.voltage.com/technology/ibe.htm Identity-Based Encryption (IBE) takes a completely new approach to the problem of encryption. IBE can use any arbitrary string as a public key, enabling data to be protected without the need for certificates. Protection is provided by a key server that controls the mapping of identities to decryption keys. It looks similar to vanish, which is time stamped and duration dependent. Also no encryption, only to a time frame. I only know and understand S/MIME and OpenPGP. IBE Identity based encryption is supposed to be easier than OpenPGP. If I remember correctly. Identity-based encryption (IBE) is a public-key encryption technology that allows a public key to be calculated from an identity, and the corresponding private key to be calculated from the public key. http://www.rfc-editor.org/rfc/rfc5091.txt Looks insecure to me.
