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...

On the Fly Authentication and Signature Schemes Based on Groups of Unknown Order
Abstract. In response to the current need for fast, secure and cheap public-key cryptography, we propose an interactive zero-knowledge identification scheme and a derived signature...

Identity-Based Threshold Decryption
Abstract. In this paper, we examine issues related to the construction of identity-based threshold decryption schemes and argue that it is important in practice to design an identi...
