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 encryption scheme which is secure against adaptive chosenciphertext attack (or CCA2-secure) in the standard model (i.e. without the use of random oracle). Our sch...
We describe a new encryption technique that is secure in the standard model against adaptive chosen ciphertext (CCA2) attacks. We base our method on two very efficient Identity-Ba...
Abstract. We propose a simple and efficient construction of a CCAsecure public-key encryption scheme from any CPA-secure identity-based encryption (IBE) scheme. Our construction re...
