Generating Searchable Public-Key Ciphertexts with Hidden Structures for Fast Keyword Search
P. Xu, Q. Wu, W. Wang +3
Existing semantically secure public-key searchable encryption schemes take search time linear with the total number of the ciphertexts. This makes retrieval from large-scale databa…
Locally Adaptive Translation for Knowledge Graph Embedding
Yantao Jia, Yuanzhuo Wang, Hailun Lin +2
Knowledge graph embedding aims to represent entities and relations in a large-scale knowledge graph as elements in a continuous vector space. Existing methods, e.g., TransE and Tra…
Quantum differential cryptanalysis to the block ciphers
Hong-Wei Li, Li Yang
Differential cryptanalysis is one of the most popular methods in attacking block ciphers. However, there still some limitations in traditional differential cryptanalysis. On the ot…
On the Integral Representation of Binary Quadratic Forms and the Artin Condition
Chang Lv, Junchao Shentu, Yingpu Deng
For diophantine equations of the form ax^2+bxy+cy^2+g=0 over Z whose coefficients satisfy some assumptions, we show that a condition with respect to Artin reciprocity map, which we…
A class of three-weight and five-weight linear codes
Fei Li, Qiuyan Wang, Dongdai Lin
Recently, linear codes with few weights have been widely studied, since they have applications in data storage systems, communication systems and consumer electronics. In this pape…
A complete Classification of Quantum Public-key Encryption Protocols
Chenmiao Wu, Li Yang
We present a classification of quantum public-key encryption protocols. There are six elements in quantum public-key encryption: plaintext, ciphertext, public-key, private-key, enc…
