Simple and Efficient KDM-CCA Secure Public Key Encryption
key dependent message security chosen ciphertext security
2019/9/16
We propose two efficient public key encryption (PKE) schemes satisfying key dependent message security against chosen ciphertext attacks (KDM-CCA security). The first one is KDM-CCA secure with respec...
Efficient Tightly-Secure Structure-Preserving Signatures and Unbounded Simulation-Sound QA-NIZK Proofs
Structure-preserving signatures QA-NIZK simulation-soundness
2019/9/16
We show how to construct structure-preserving signatures (SPS) and unbounded quasi-adaptive non-interactive zero-knowledge (USS QA-NIZK) proofs with a tight security reduction to simple assumptions, b...
An efficient and secure ID-based multi-proxy multi-signature scheme based on lattice
multi-proxy multi-signature scheme multi-signature scheme ID-based signature
2019/9/16
Multi-proxy multi-signature schemes are useful in distributed networks, where a group of users cooperatively could delegate their administrative rights to the users of another group, who are authorize...
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 ...
There Are 10 Types of Vectors (and Polynomials): Efficient Zero-Knowledge Proofs of "One-Hotness" via Polynomials with One Zero
Zero-knowledge efficiency privacy-preserving protocols
2019/8/30
We present a new 4-move special honest-verifier zero-knowledge proof of knowledge system for proving that a vector of Pedersen commitments opens to a so-called "one-hot" vector (i.e., to a vector from...
Efficient zero-knowledge arguments in the discrete log setting, revisited
zero-knowledge argument quadratic equations arithmetic circuit satisfiability
2019/8/20
This work revisits zero-knowledge proofs in the discrete logarithm setting. First, we identify and carve out basic techniques (partly being used implicitly before) to optimize proofs in this setting. ...
Improvements in Everlasting Privacy: Efficient and Secure Zero Knowledge Proofs
Voting Everlasting Privacy Zero Knowledge Proofs
2019/8/8
Verifiable electronic voting promises to ensure the correctness of elections even in the presence of a corrupt authority, while providing strong privacy guarantees. However, few practical systems with...
Efficient and secure software implementations of Fantomas
LS-Design Fantomas side-channel resistance
2019/8/8
In this paper, the efficient software implementation and side-channel resistance of the LS-Design construction is studied through a series of software implementations of the Fantomas block cipher, one...
A new implementation of Falcon is presented. It solves longstanding issues in the existing reference code: the new implementation is constant-time, it does not require floating-point hardware (though ...
Efficient Information-Theoretic Secure Multiparty Computation over Z/pkZ via Galois Rings
MPC Galois Rings
2019/7/30
At CRYPTO 2018, Cramer et al. introduced a secret-sharing based protocol called SPDZ2kZ2k that allows for secure multiparty computation (MPC) in the dishonest majority setting over the ring of integer...
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...
k-root-n: An efficient O(√n) algorithm for avoiding short term double spending in Distributed Ledger Technologies such as Blockchain
Blockchain bitcoin distributed ledger technology
2019/7/17
Blockchains such as bitcoin rely on reaching global consensus for the distributed ledger, and suffer from a well know scalability problem. We propose an algorithm which can avoid double spending in th...
Simple and Efficient Approach for Achieving End-to-End Anonymous Communication
cryptographic protocols Anonymous communication
2019/7/15
Anonymous communication, that is secure end-to-end and unlinkable, plays a critical role in protecting user privacy by preventing service providers from using message metadata to discover communicatio...
RISC-V is a promising free and open-source instruction set architecture. Most of the instruction set has been standardized and several hardware implementations are commercially available. In this pape...
