Toshihide Matsuda, Ryo Nishimaki, Keisuke Tanaka
2010 Lecture Notes in Computer Science  
In this paper, we construct a bidirectional PRE-CCA proxy re-encryption without bilinear maps in the standard model.  ...  However, some PRE schemes need a bilinear map in the standard model, and the other PRE schemes are PRE-CCA secure in the random oracle model before our work.  ...  Our Contribution We construct a bidirectional and multi-hop PRE-CCA scheme without bilinear maps in the standard model. All previous PRE-CCA secure schemes in the standard model use bilinear maps.  ...

Our construction is efficient and based only on the Decisional Bilinear Diffie-Hellman assumption in the standard model.  ...  In a proxy re-encryption (PRE) scheme, a proxy is given special information that allows it to translate a ciphertext under one key into a ciphertext of the same message under a different key.  ...  Their CCA IBE scheme is unidirectional and single-hop in the random oracle model, whereas ours is bidirectional and multihop in the standard model.  ...
