ABSTRACT: A
recent proposal by Adams integrates the digital credentials (DC) technology of
Brands with the identity-based encryption (IBE) technology of Boneh and
Franklin to create an IBE scheme that demonstrably enhances privacy for users.
We refer to this scheme as a privacy-preserving identity-based encryption (PP-IBE)
construction. In this paper, we discuss the concrete implementation
considerations for PP-IBE and provide a detailed instantiation (based on q-torsion groups in supersingular
elliptic curves) that may be useful both for proof-of-concept purposes and for
pedagogical purposes.
