In this article, we demonstrate practical side-channel assisted chosen-ciphertext attacks (CCA) over multiple CCA-secure lattice-based public-key encryption schemes (PKE) and key-encapsulation mechani...
We investigate the minimal number of group elements and prover running time in a zk-SNARK when using only a symmetric ``linear'' knowledge assumption, like the dd-Power Knowledge of Exponent assumptio...
Based on the identity-based encryption (IBE) from lattices by Agrawal et al. (Eurocrypt'10), Micciancio and Peikert (Eurocrypt'12) presented a CCA1-secure public-key encryption (PKE), which has the be...
Hard learning problems are central topics in recent cryptographic research. Many cryptographic primitives relate their security to difficult problems in lattices, such as the shortest vector problem. ...
In the situation where there are one sender and multiple receivers, a receiver selective opening (RSO) attack for a public key encryption (PKE) scheme considers adversaries that can corrupt some of th...
Cryptographic primitives that are secure against quantum computing are receiving growing attention with recent, steady advances in quantum computing and standardization initiatives in post-quantum cry...
The goal of leakage-resilient cryptography is to construct cryptographic algorithms that are secure even if the adversary obtains side-channel information from the real world implementation of these a...
In this paper, we define new RKA security notions for several cryptographic primitives including message authentication code (MAC), public-key encryption (PKE) and symmetric encryption (SE). This new ...
We construct an identity-based encryption (IBE) scheme from the standard Learning with Errors (LWE) assumption, which both has a compact public-key (with size similar to known lattice-based PKE sche...
We study simulation-based, selective opening security against chosen-ciphertext attacks (SIM-SO-CCA security) for public key encryption (PKE). In a selective opening, chosen-ciphertext attack (SO-CCA)...
We show that (leveled) fully homomorphic encryption (FHE) can be based on the hardness of $\otild(n^{1.5+\epsilon})$-approximation for lattice problems (such as GapSVP) under quantum reductions for an...
Design efficient Lattice-based cryptosystem secure against adaptive chosen ciphertext attack (IND-CCA2) is a challenge problem. To the date, full CCA2-security of all proposed Lattice-based PKE scheme...
Recently, Baek et al. proposed a stateful identity based encryption scheme with compact ciphertext and commented that the security of the scheme can be reduced to the Computational Bilinear Diffie Hel...
Recently in Chinese Journal of Computers, Kang et al. [12] proposed an efficient CCA secure public key encryption (PKE) scheme, and claimed that it is more efficient in the public/private keys than th...
Recently, Al-Riyami and Paterson proposed a generic con- version from CL-PKE (Certificateless Public Key Encryption) to CBE (Certificate Based Encryption) and claimed that the derived CBE scheme is...
