Abstract. In 1998, Blaze, Bleumer, and Strauss proposed a cryptographic primitive called proxy re-encryption, in which a proxy transforms – without seeing the corresponding plain...
Abstract. We present a non-interactive chosen ciphertext secure threshold encryption system. The proof of security is set in the standard model and does not use random oracles. Our...
We present a new approach for creating chosen ciphertext secure encryption. The focal point ork is a new abstraction that we call Detectable Chosen Ciphertext Security (DCCA). Int...
