A New Public Key Cryptosystem Based on Edwards Curves
Elliptic curves Twisted Edwards curves RSA cryptosystem
2019/9/19
The elliptic curve cryptography plays a central role in various cryptographic schemes and protocols. For efficiency reasons, Edwards curves and twisted Edwards curves have been introduced. In this pap...
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...
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.
Towards a Hybrid Public Key Infrastructure (PKI): A Review
Certificate-based PKI Identity-based public key cryptography (ID-PKC) Hybrid PKI
2019/7/15
Traditional Certificate-based public key infrastructure (PKI) suffers from the problem of certificate overhead like its storage, verification, revocation etc. To overcome these problems, the idea of c...
DDH-based Multisignatures with Public Key Aggregation
Multisignatures Decisional Diffie-Hellman assumption Blockchain
2019/7/8
A multisignature scheme allows a group of signers to produce a joint signature on a common message, which is more compact than a collection of distinct signatures from all signers. Given this signatur...
Public-Key Function-Private Hidden Vector Encryption (and More)
function privacy obfuscation conjunctions
2019/6/26
Conjunctions. If the predicate computes a conjunction, our construction is a public-key function-private hidden vector encryption scheme. This addresses an open problem posed by Boneh, Raghunathan, an...
Public Ledger for Sensitive Data
Privacy-Preserving Ledger Blockchain End to End Encryption
2019/6/19
In this work an original protocol is presented that allows sensitive data to be stored on a ledger where its integrity may be publicly verified, but its privacy is preserved and owners can tightly man...
Homomorphism learning problems and its applications to public-key cryptography
Learning With Errors isogenies non-commutative cryptography
2019/6/19
We present a framework for the study of a learning problem over abstract groups, and introduce a new technique which allows for public-key encryption using generic groups. We proved, however, that in ...
Public-Key Cryptography in the Fine-Grained Setting
Fine-grained Public-Key One-Way-Function
2019/6/4
Cryptography is largely based on unproven assumptions, which, while believable, might fail. Notably if P=NPP=NP, or if we live in Pessiland, then all current cryptographic assumptions will be broken. ...
A software watermarking scheme enables users to embed a message or mark within a program while preserving its functionality. Moreover, it is difficult for an adversary to remove a watermark from a mar...
Pseudorandom functions are traditionally built upon block ciphers, but with the trend of permutation based cryptography, it is a natural question to investigate the design of pseudorandom functions fr...
Non-malleability for quantum public-key encryption
public-key cryptography non-malleability quantum cryptography
2019/5/21
Non-malleability is an important security property for public-key encryption (PKE). Its significance is due to the fundamental unachievability of integrity and authenticity guarantees in this setting,...
Dual Isogenies and Their Application to Public-key Compression for Isogeny-based Cryptography
Post-quantum cryptography public-key compression supersingular elliptic curves
2019/5/21
The isogeny-based protocols SIDH and SIKE have received much attention for being post-quantum key agreement candidates that retain relatively small keys. A recent line of work has proposed and further...
