Toward Constant Size CCA-secure Multi-hop Proxy Re-encryption

摘要：

Blaze et al.in 1998 introduced the concept of proxy re-encryption, which allows a proxy to transform a ciphertext computed under Alices pubLic key into one that can be opened under Bobs decryption key. But until now, the problem of constructing a constant-size CCA-secure multi-hop proxy re encryption scheme remain opem In this paper, we try to solve this open problem by presenting a somewhat constantsize CCAsecure multi-hop proxy re-encryption scheme.

关键词： Proxy re-encryption CCA-secure constant size multi-hop.
