We continue a study of unconditionally secure all-or-nothing transforms (AONT) begun
in\cite {St}. An AONT is a bijective mapping that constructs s outputs from s inputs. We …

For given positive integers t≤ s, what is the maximum number of t-by-t invertible submatrices
in an invertible binary matrix of order s? This purely combinatorial problem is posedrecently …

An all-or-nothing transform is an invertible function that maps s inputs to s outputs such that,
in the calculation of the inverse, the absence of only one output makes it impossible for an …

如何保护敏感数据和传感器节点的位置信息在无线传感器网络的应用过程中不被泄露,
是无线传感器网络面临的重大挑战. 文中针对现有隐私保护技术的不足, 通过引入同态加密技术 …

Network coding is a technique mainly used to maximize the throughput, minimize the delay,
or optimize the reliability in the communication networks. However, network coding presents …

The research on all-or-nothing transform in cryptography leads to the problem that, for a
given positive integer, what is the density of invertible submatrices of any invertible matrix …

To provide security for data gathering based on network coding in wireless sensor networks
(WSNs), a secure network coding-based data gathering model is proposed, and a data …
