Identity-Based Decryption

Daniel R. L. Brown

Abstract

Identity-based decryption is an alternative to identity-based encryption, in which Alice encrypts a symmetric key for Bob under a trusted authority’s public key. Alice sends Bob the resulting ciphertext, which Bob can send to the trusted authority. The trusted authority provides Bob the symmetric key only upon verifying Bob’s identity.

Note: Informed of previous similar work.
