This is identity based encryption,
I've heard about it.
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.
Looks insecure to me.
