چکیده

We present a certificate-based encryption scheme which is fully secure in the standard model. Our scheme is based on the identity-based encryption scheme of Waters [16]. Although some generic constructions from IBE to CBE has been previously proposed, they use the Random Oracle heuristic or provide less practical schemes than ours. Finally, we point out that one of the existing generic constructions going from IBE to CBE is flawed.

Efficient Certificate-Based Encryption Scheme Secure Against Key Replacement Attacks in the Standard Model

Certificate-based encryption is a useful primitive that combines traditional public key encryption and identity-based encryption while preserving some of their most attractive features. It not only simplifies the cumbersome certificate management in traditional PKI, but also solves the key escrow problem inherent in identity-based encryption. In this paper, we propose a new certificate-based en...

Identity based signcryption scheme without random oracles

Signcryption is a cryptographic primitive which performs encryption and signature in a single logical step with the cost lower than signature-then-encryption approach.. In this paper we gave attacks on confidentiality and unforgeability of two identity based signcryption schemes without random oracles. Further we proposed an improved identity based signcryption scheme without random oracles. We...

A Fully Secure Revocable ID-Based Encryption in the Standard Model

Revocation problem is a critical issue for key management of public key systems. Any certificate-based or identity (ID)-based public key systems must provide a revocation method to revoke misbehaving/compromised users from the public key systems. In the past, there was little work on studying the revocation problem of ID-based public key systems. Most recently, Tseng and Tsai presented a novel ...

Efficient Identity-Based Encryption Without Random Oracles

We present the first efficient Identity-Based Encryption (IBE) scheme that is fully secure without random oracles. We first present our IBE construction and reduce the security of our scheme to the decisional Bilinear Diffie-Hellman (BDH) problem. Additionally, we show that our techniques can be used to build a new signature scheme that is secure under the computational Diffie-Hellman assumptio...

Toward Certificateless Signcryption Scheme Without Random Oracles

Signcryption is a useful paradigm which simultaneously offers both the functions of encryption and signature in a single logic step. It would be interesting to make signcryption certificateless to ease the heavy burden of certificate management in traditional public key cryptography (PKC) and solve the key escrow problem in Identity-based public key cryptography (ID-PKC). Most certificateless s...
