At CRYPTO 2017, Rosca et al. introduce a new variant of the Learning With Errors (LWE) problem, called the Middle-Product LWE (MP-LWE). The hardness of this new assumption is based on the hardness of ...
RAMPARTS: A Programmer-Friendly System for Building Homomorphic Encryption Applications
Homomorphic encryption Automatic arithmetic circuit generation Lattice-based cryptography
2019/9/3
Homomorphic Encryption (HE) is an emerging technnology that enables computing on data while the data is encrypted. A major challenge with homomorphic encryption is that it takes extensive expert knowl...
Efficient Range-Trapdoor Functions and Applications: Rate-1 OT and More
Trapdoor functions range trapdoor hash power DDH
2019/9/3
Substantial work on trapdoor functions (TDFs) has led to many powerful notions and applications. However, despite tremendous work and progress, all known constructions have prohibitively large public ...

Hardware reverse engineering is a powerful and universal tool for both security engineers and adversaries. From a defensive perspective, it allows for detection of intellectual property infringements ...
Structure-Preserving and Re-randomizable RCCA-secure Public Key Encryption and its Applications
public-key cryptography Rand-RCCA PKE
2019/8/22
Re-randomizable RCCA-secure public key encryption (Rand-RCCA PKE) schemes reconcile the property of re-randomizability of the ciphertexts with the need of security against chosen-ciphertexts attacks.
Traceable and linkable ring signatures, traceable range proofs and applications on regulatable privacy-preserving blockchains
regulatable blockchain privacy preserving decentralization

Privacy protection has been extensively studied in the current blockchain research field. As representations, Monero and Zerocash have realized completely anonymous and amount-hiding transactions. How...
Simulation-Sound Proofs for LWE and Applications to KDM-CCA2 Security
LWE standard model Naor-Yung
2019/8/8
The Naor-Yung paradigm is a well-known technique that constructs IND-CCA2-secure encryption schemes by means of non-interactive zero-knowledge proofs satisfying a notion of simulation-soundness. Until...
Invariant subspaces (Crypto'11) and subspace trails (FSE'17) are two related recent cryptanalytic approaches that led to new results on, e. g. PRINTCipher and AES. We extend the invariant subspace app...
Asymptotically-Good Arithmetic Secret Sharing over Z/(p^\ell Z) with Strong Multiplication and Its Applications to Efficient MPC
multiparty computation amortization information-theoretical security
2019/7/18
This paper deals with (1) asymptotics of ``strongly-multiplicative'' arithmetic secret sharing over an arbitrary fixed ring Rℓ:=Z/pℓZ (p>0 prime, ℓ>0 an integer) and supporting an un...
