The security of traditional attribute-based searchable encryption schemes relies on traditional number-theoretic assumptions, and thus they are not able to resist the threat of quantum algorithms.

In what became known as attribute-based encryption (ABE), decisions to decrypt turned on policies rather than individual identities. The paper proved influential. Building upon it, particularly ...

The checking of those attributes happens mathematically, ‘inside the crypto,’ which shifts attention away from servers or software engineering towards policies and the encryption itself ...
