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...

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...

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...
