Estimating local agricultural gross domestic product (AgGDP) across the world
agricultural gross domestic product across the world
2024/4/1
Economic statistics are frequently produced at an administrative level such as the subnational division. However, these measures may lack sufficient local variation for effective analysis of local eco...
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 ...
Detecting Faults in Inner Product Masking Scheme - IPM-FD: IPM with Fault Detection
Side-channel Analysis Inner Product Masking Fault Detection
2019/8/14
Side-channel analysis and fault injection attacks are two typical threats to cryptographic implementations, especially in modern embedded devices. Thus there is an insistent demand for dual side-chann...
Practical Attribute Based Inner Product Functional Encryption from Simple Assumptions
Functional Encryption Attribute Based Encryption Inner Product
2019/7/23
Functional encryption (FE) that bases on user attributes has many useful practical applications. For example, a company may only authorize department heads of other sections to query the average sale ...
Non-zero Inner Product Encryptions: Strong Security under Standard Assumptions
non-zero inner product encryptions adaptive security payload- hiding
2019/7/15
Non-zero inner product encryption (NIPE) allows a user to encrypt a message with its attribute vector and decryption is possible using a secret-key associated with a predicate vector if the inner prod...
Obfuscated Fuzzy Hamming Distance and Conjunctions from Subset Product Problems
Program Obfuscation Hamming Distance Conjunctions
2019/6/4
We consider the problem of obfuscating programs for fuzzy matching (in other words, testing whether the Hamming distance between an nn-bit input and a fixed nn-bit target vector is smaller than some p...
Discretisation and Product Distributions in Ring-LWE
Ring-LWE Discretisation Homomorphic Encryption
2019/6/3
A statistical framework applicable to Ring-LWE was outlined by Murphy and Player (IACR eprint 2019/452). Its applicability was demonstrated with an analysis of the decryption failure probability for d...
From Single-Input to Multi-Client Inner-Product Functional Encryption
Decentralized multi-client functional encryption inner products
2019/5/21
We present a new generic construction of multi-client functional encryption (MCFE) for inner products from single-input functional inner-product encryption and standard pseudorandom functions. In spit...
Tightly Secure Inner Product Functional Encryption: Multi-Input and Function-Hiding Constructions
functional encryption inner product tight security
2019/2/27
Tightly secure cryptographic schemes have been extensively studied in the fields of chosen-ciphertext secure public-key encryption (CCA-secure PKE), identity-based encryption (IBE), signature and more...
Non-Zero Inner Product Encryption Schemes from Various Assumptions: LWE, DDH and DCR
Non-zero inner product encryption lattices generic constructions functional encryption for inner products
2019/1/18
In non-zero inner product encryption (NIPE) schemes, ciphertexts and secret keys are associated with vectors and decryption is possible whenever the inner product of these vectors does not equal zero....
Decentralizing Inner-Product Functional Encryption
Decentralized multi-client functional encryption inner products
2019/1/9
Multi-client functional encryption (MCFE) is a more flexible variant of functional encryption whose functional decryption involves multiple ciphertexts from different parties. Each party holds a diffe...

2018/11/16
In this work, we propose two IPE schemes achieving both adaptive security and full attribute-hiding in the prime-order bilinear group, which improve upon the unique existing result satisfying both fea...
