Anonymous IBE, Leakage Resilience and Circular Security from New Assumptions
identity-based encryption anonymity leakage resilience
2017/10/9
In anonymous identity-based encryption (IBE), ciphertexts not only hide their corresponding messages, but also their target identity. We construct an anonymous IBE scheme based on the Computational Di...
Anonymous IBE from Quadratic Residuosity with Improved Performance
Identity Based Encryption Anonymous IBE Cocks Scheme
2016/1/6
Identity Based Encryption (IBE) has been constructed from bilinear pairings,
lattices and quadratic residuosity. The latter is an attractive basis for an IBE owing to the
fact that it is a well-unde...
Universally Anonymous IBE based on the Quadratic Residuosity Assumption
Universally Anonymous IBE Quadratic Residuosity Assumption
2009/6/23
We introduce the first universally anonymous, thus key-private, IBE whose security is based
on the standard quadratic residuosity assumption. Our scheme is a variant of Cocks IBE (which
is not anony...
Searchable Encryption Revisited: Consistency Properties, Relation to Anonymous IBE, and Extensions
Searchable Encryption Consistency Properties Anonymous IBE
2009/2/20
We identify and fill some gaps with regard to consistency (the extent to which false positives
are produced) for public-key encryption with keyword search (PEKS). We define computational
and statist...
