With the emerging of new types of network forms, services and cloud computation, the situation has transformed from one party to many parties at least one of both communication ends, that is "one-to-many," "manytoone," and "many-to-many" situations. Most of the existing fully homomorphic encryption schemes only allow one party to encrypt the plaintext and another party to decrypt the ciphertext without the decryption keys. This form of cryptography loses efficiency under the demands of "one-to-many," "many-to-one," and "many-to-many" scenarios. In this paper, we combine the fully homomorphic encryption with proxy re-encryption to propose the fully homomorphic proxy re-encryption scheme which can be applied to "many-to-one" scenario, that is the fully homomorphic proxy re-encryption scheme allows one party to compute arbitrary functions over encrypted data for many parties without the decryption keys. Finally, INDCPA, KP-CPA and master secret security proof of our proposal are given. © 2019, International Journal of Network security.

This paper presents a novel super-resolution time of arrive(TOA) estimation algorithm, which utilizes the primary synchronization signal(PSS) in LTE downlink. Unlike the conventional coherent detection algorithm with sample-level estimation accuracy, the proposed algorithm fully takes advantage of phase characteristic of the sampled orthogonal frequency division multiplexing(OFDM) signal to reach subsample resolution accuracy without increasing sampling frequency. With a number of simulation experiments, the efficacy of the proposed TOA estimation algorithm is validated by numerical results. The different performance shown in additive white Gaussian noise(AWGN) channel and fading channel indicates that this algorithm can be used in open environment or indoors with high-precision positioning requirements.

It has been challenging work to identify block ciphers under CBC mode over the past few decades. But we can still conduct the identification of block ciphers under CBC mode if enough ciphertext streams are available. In this paper, we consider the identification of 5 frequently used block ciphers, AES, DES, 3DES, RC5 and Blowfish. For multi-class identification, the identification rate of 5 block ciphers can reach above 90% as long as the size of ciphertext file is larger than 100 KB when same key and same IV for training and testing ciphertext files. For one to one identification, we identify AES from other 4 block ciphers on condition of different keys or different IVs for training and testing ciphertext files. We can obtain an identification rate of above 97% when the size of ciphertext file is equal to 100 KB. Besides, even if the size of ciphertext file is only 4 KB, the average identification rate is still higher than 80%. © 2018 The Authors. Published by Elsevier Ltd.

Multipath TCP (MPTCP) enables terminals utilizing multiple interfaces for data transmission simultaneously, which provides better performance and brings many benefits. However, using multiple paths brings some new challenges. The asymmetric parameters among different subflows may cause the out-of-order problem and load imbalance problem, especially in wireless network which has more packet loss. Thus it will significantly degrade the performance of MPTCP. In this paper, we propose a Receive Buffer Pre-division based flow control mechanism (RBP) for MPTCP. RBP divides receive buffer according to the prediction of receive buffer occupancy of each subflow, and controls the data transmission on each subflow using the divided buffer and the number of out-of-order packets, which can significantly improve the performance of MPTCP. We use the NS-3 simulations to verify the performance of our scheme, and the simulation results show that RBP algorithm can significantly increase the global throughput of MPTCP. © Springer Nature Singapore Pte Ltd. 2018.

Age of information (AoI) is an important metric in real-time status update communication system to assess the freshness of information. Different from previous works, this paper focuses on the average AoI over additive white Gaussian noise (AWGN) channels. A fixed redundancy (FR) coding scheme is considered, which encodes each k-bits update as an n-bits packet by a low-density parity-check (LDPC) code. By using the renewal-reward theory, a closed-form expression of the average AoI under the FR scheme is derived. Simulation results show that the average AoI relies on E_b/N_0, especially in the low E_b/N_0 region. For different E_b/N_0, an optimal code length always exists to minimize the average AoI. In addition, the same average AoI can be achieved with different code lengths in the high E_b/N_0 region. Hence, in the high E_b/N_0 region, short codes are preferred especially when the transmission delay is taken into account.

Secure communications in a unified non-orthogonal multiple access framework

arXiv 2019年

作者： Yue, Xinwei Liu, Yuanwei Yao, Yuanyuan Li, Xuehua Liu, Rongke Nallanathan, Arumugam School of Information and Communication Engineering Key Laboratory of Modern Measurement & Control Technology Ministry of Education Beijing Information Science and Technology University Beijing100101 China School of Electronic Engineering and Computer Science Queen Mary University of London LondonE1 4NS United Kingdom School of Electronic and Information Engineering Beihang University Beijing100191 China

This paper investigates the impact of physical layer secrecy on the performance of a unified non-orthogonal multiple access (NOMA) framework, where both external and internal eavesdropping scenarios are examined. The spatial locations of legitimate users (LUs) and eavesdroppers are modeled by invoking stochastic geometry. To characterize the security performance, new exact and asymptotic expressions of secrecy outage probability (SOP) are derived for both code-domain NOMA (CD-NOMA) and power-domain NOMA (PD-NOMA), in which imperfect successive interference cancellation (ipSIC) and perfect SIC (pSIC) are taken into account. For the external eavesdropping scenario, the secrecy diversity orders by a pair of LUs (the n-th user and m-th user) for CD/PD-NOMA are obtained. Analytical results make known that the diversity orders of the n-th user with ipSIC/pSIC for CD-NOMA and PD-NOMA are equal to zero/ K and zero/one, respectively. The diversity orders of the m-th user are equal to K/one for CD/PD-NOMA. For the internal eavesdropping scenario, we examine the analysis of secrecy diversity order and observe that the m-th user to wiretap the n-th user with ipSIC/pSIC for CD-NOMA and PDNOMA provide the diversity orders of zero/K and zero/one, respectively, which is consistent with external eavesdropping scenario. Numerical results are present to confirm the accuracy of the analytical results developed and show that: i) The secrecy outage behavior of the n-th user is superior to that of the m-th user;ii) By increasing the number of subcarriers, CD-NOMA is capable of achieving a larger secrecy diversity gain compared to PD-NOMA.
