Security Analysis Based on Quantum Random Oracle Model
2020Random oracle model is a general security analysis tool for rigorous security proof and effective cryptographic protocol design. In the quantum world, the attempts of constructing a quantum random oracle (QRO) have been made, such as quantum-accessible random oracle for post-quantum cryptography and quantum random oracle for quantum cryptography.

Selectively Convertible Authenticated Encryption in the Random Oracle Model
The Computer Journal, 2007Conventionally, a verified digital signature releases information about both the signing event and the signed content simultaneously, where the signing event proves the truth that someone actually signed something. However, in many cases, the information of the signing event and the signed content have different uses and distinct degrees of importance ...

Securing “Encryption + Proof of Knowledge” in the Random Oracle Model [PDF]
, 2002 To create encryption schemes that offer security against adaptive chosen ciphertext attacks, this paper shows how to securely combine a simple encryption scheme with a proof of knowledge made noninteractive with a hash function. A typical example would be combining the ElGamal encryption scheme with the Schnorr signature scheme.

IBE in Adaptive-Identity Model Without Random Oracles
2011In the previous chapters, we have seen several IBE schemes and their extension to HIBE. As mentioned in Chapter 2, the security model for IBE schemes was introduced by Boneh and Franklin and allows the adversary to make both adaptiveidentity and adaptive-chosen ciphertext attacks.

Secure Stern Signatures in Quantum Random Oracle Model
2019The Stern signatures are a class of lattice-based signatures constructed from Stern protocols, a special class of sigma protocols, admitting diverse functionalities with good asymptotic efficiency. However, the post-quantum security of existing Stern signatures is unclear, since they are built via the Fiat-Shamir transformation, which has not been ...

Fiat–Shamir Bulletproofs are Non-malleable (in the Random Oracle Model)
Journal of CryptologyBulletproofs (Bünz et al., in: 2018 IEEE symposium on security and privacy, IEEE Computer Society Press, pp 315–334, 2018) are a celebrated ZK proof system that allows for short and efficient proofs, and have been implemented and deployed in several real-world systems.
