“…In the last paper of the second theme entitled ''Separable Reversible Data Hiding and Encryption for HEVC Video'' by Long et al [15], one can encrypt the signs and amplitudes of motion vector differences (MVD) and the signs of residual coefficients with an encryption key by using RC4, while another can hide data into nonzero AC residual coefficients with a hiding key. For the decoding phase, one can decrypt the HEVC video and obtain a HEVC video similar to the original one if he only has the encryption key; he can extract the hiding data without knowing the HEVC video content if he only has the hiding key; he can extract the hiding data and recover the original HEVC video if he has both the encryption key and hiding key.…”

“…Therefore, compared with images, videos have much more research room to develop the techniques of RDH and DH. Recently, as the development of video compression standard, such as H.264/advanced video coding (AVC) 9 and high-efficiency video coding (HEVC), 10 some video DH methods 2,[11][12][13][14][15][16] and video RDH methods [17][18][19][20][21][22][23] are reported. For these DH methods, they are proposed for improving embedding capacity, 12,14 stopping intra-frame drift, 11,13,16 and reducing bit-rate increase.…”

Developing the technology of reversible data hiding based on video compression standard, such as H.264/advanced video coding, has attracted increasing attention from researchers. Because it can be applied in some applications, such as error concealment and privacy protection. This has motivated us to propose a novel two-dimensional reversible data hiding method with high embedding capacity in this article. In this method, all selected quantized discrete cosine transform coefficients are first paired two by two. And then, each zero coefficient-pair can embed 3 information bits and the coefficient-pairs only containing one zero coefficient can embed 1 information bit. In addition, only one coefficient of each one of the rest coefficient-pairs needs to be changed for reversibility. Therefore, the proposed two-dimensional reversible data hiding method can obtain high embedding capacity when compared with the related work. Moreover, the proposed method leads to less degradation in terms of peak-signal-to-noise ratio, structural similarity index, and less impact on bit-rate increase.

“…In recent years, various technologies have been broadly used for data privacy protection, such as private information retrieval [6][7][8][9][10][11], searchable encryption [12][13][14][15][16][17], and secure multi-party computation [18][19][20][21][22][23], but these technologies can only provide limited functions, such as keyword search, order search, range query, and subset search. However, for many application scenarios in the cloud environment, it requires various types operations of ciphertext data.…”

Cyber physical system (CPS) is facing enormous security challenges because of open and interconnected network and the interaction between cyber components and physical components, the development of cyber physical systems is constrained by security and privacy threats. A feasible solution is to combine the fully homomorphic encryption (FHE) technique to realize the efficient operation of ciphertext without decryption. However, most current homomorphic encryption algorithms only support limited data types, making it difficult to be widely applied in actual environment. To address this limitation, we propose a parallel fully homomorphic encryption algorithm that supports floating-point numbers. The proposed algorithm not only expands the data types supported by the existing fully homomorphic encryption algorithms, but also utilizes the characteristics of multi-nodes in cloud environment to conduct parallel encryption through simultaneous group-wise ciphertext computations. The experimental results show that, in a 16-core 4-node cluster with MapReduce environment, the proposed encryption algorithm achieves the maximum speed-up exceeding 5, which not only solves the limited application problem of the existing fully homomorphic encryption algorithm, but also meets the requirements for the efficient homomorphic encryption of floating-point numbers in cloud computing environment.
