In 1998, Blaze, Bleumer, and Strauss (BBS) proposed an application called atomic proxy re-encryption , in which a semitrusted converts ciphertext for Alice into Bob without seeing the underlying plaintext. We predict that fast secure will become increasingly popular as method managing encrypted file systems. Although efficiently computable, wide-spread adoption of BBS has been hindered by considerable security risks. Following recent work Dodis Ivan, we present new schemes realize stronger notion demonstrate usefulness adding access control to system. Performance measurements our experimental system can effectively practice.
