  author={Somindu C. Ramanna and Palash Sarkar},
We present two hierarchical identity-based encryption (HIBE) schemes, denoted as H1 and H2, from Type-3 pairings with constant sized ciphertexts. Scheme H1 achieves anonymity while H2 is non-anonymous. The constructions are obtained by extending the IBE scheme recently proposed by Jutla and Roy (Asiacrypt 2013). Security is based on the standard decisional… CONTINUE READING
