Adaptive Modular Exponentiation Methods v.s. Python's Power Function
Shiyu Ji, Kun Wan
In this paper we use Python to implement two efficient modular exponentiation methods: the adaptive m-ary method and the adaptive sliding-window method of window size k, where both…
An Asymptotically Tighter Bound on Sampling for Frequent Itemsets Mining
Shiyu Ji, Kun Wan
In this paper we present a new error bound on sampling algorithms for frequent itemsets mining. We show that the new bound is asymptotically tighter than the state-of-art bounds, i…
k-Anonymously Private Search over Encrypted Data
Shiyu Ji, Kun Wan
In this paper we compare the performance of various homomorphic encryption methods on a private search scheme that can achieve -anonymity privacy. To make our benchmarking fair,…
On the Correctness of Inverted Index Based Public-Key Searchable Encryption Scheme for Multi-time Search
Shiyu Ji
In this short note we argue that the state-of-art inverted index based public key searchable encryption scheme proposed by Wang et al may not be completely correct by giving a coun…
On Credit-based Incentive Mechanisms of Voluntary User Comment Reviewing in Social Networks
Shiyu Ji
With the recent advance of micro-blogs and social networks, people can view and post comments on the websites in a very convenient way. However, it is also a big concern that the m…
Refining Approximating Betweenness Centrality Based on Samplings
Shiyu Ji, Zenghui Yan
Betweenness Centrality (BC) is an important measure used widely in complex network analysis, such as social network, web page search, etc. Computing the exact BC values is highly t…
Image encryption schemes for JPEG and GIF formats based on 3D baker with compound chaotic sequence generator
Shiyu Ji, Xiaojun Tong, Miao Zhang
This paper proposed several methods to transplant the compound chaotic image encryption scheme with permutation based on 3D baker into image formats as Joint Photographic Experts G…
