Chosen Ciphertext Secure Public Key Threshold Encryption Without Random Oracles
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...

Chosen-Ciphertext Security from Identity-Based Encryption
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...

Strongly Unforgeable Signatures and Hierarchical Identity-Based Signatures from Lattices without Random Oracles
Abstract. We propose a variant of the “bonsai tree” signature scheme, a latticebased existentially unforgeable signature scheme in the standard model. Our construction offers ...

HIBE With Short Public Parameters Without Random Oracle
Abstract. At Eurocrypt 2005, Waters presented an identity based encryption (IBE) protocol which is secure in the full model without random oracle. In this paper, we extend Waters&#...
