Universally composable oblivious transfer protocol based on VSPH by LI Feng-hua1, FENG Tao1, MA Jian-feng1

“…A new oblivious transfer protocol was proposed within the framework of universally composable security（UC-DT）.The protocol based on the verifiably smooth projective hashing（VSPH） is against adaptive adversaries in a common reference string（CRS） model.The UC-OT protocol improves computational efficiency with non-committing encryptions（NCE）which is based on decisional compounding residuosity,achieves UC-OT,and it saves O（n）-1 rounds in communication efficiency than bit-OT protocols.Compared with Canetti’s scheme in non-erase model,the message reduced once.Compared with Fischlin’s scheme,the message transfers were reduced twice,and the scheme does not rely on the auxiliary party,therefore it is more practical.…”

Complexity control method of random forest based HEVC by Peng WEN, Zongju PENG, Fen CHEN, Gangyi JIANG, Mei YU

“…High efficiency video coding (HEVC) has high computational complexity,and fast algorithm cannot perform video coding under restricted coding time.Therefore,a complexity control method of HEVC based on random forest was proposed.Firstly,three random forest classifiers with different prediction accuracy were trained to provide various coding configurations for coding tree unit (CTU).Then,an average depth-complexity model was built to allocate CTU complexity.Finally,the CTU coding configuration,determined by the smoothness,average depth,bit,and CTU-level accumulated coding error,was used to complete complexity control.The experimental results show that the proposed method has better complexity control precision,and outperforms the state-of-the-art method in terms of video quality.…”

Privacy matching-based service proxy discovery scheme by Kui GENG, Sheng WAN, Feng-hua LI, Yuan-yuan HE, Han-yi WANG

“…According to user's requirements on the proxy performance,cost and safety in proxy discovery,and the pri-vacy-preserving issue during the process of the demand private matching,a new private matching algorithm was pre-sented based on Paillier homomorphic encryption,comprehensively considered the attributes of user and agents and their priority.It included four steps:building the similarity function based on Euclidean distance,carrying on the private matching by encryption algorithm,calculating the similarity and screening the proxy chain.Proposed scheme introduced semi trusted primary proxy from the global level,which is to manage all the sub proxy's business type and the connection status,and do the main computational overhead.At the same time,Euclidean distance and Paillier homomorphic encryp-tion algorithm were combined to support the multivariate attributes with priority to match,which can effectively protect the privacy of user and sub proxy.Finally,security analysis and evaluation results show the effectiveness and safety of proposed scheme.…”

TPCM-based trusted PXE boot method for servers by Guojie LIU, Jianbiao ZHANG

“…The PXE startup mechanism downloads operating system files through the network and starts the operating system,which is widely used in server network startup.It is widely used in server network startup.The PXE boot process is secured and trusted through trusted computing technology to prevent the PXE boot file from being tampered with maliciously,ensuring the safe and reliable operation of the server.The cyber security classified protection standard requires that the system boot program and system program of the server device be trusted and verified based on the trusted root.A TPCM-based server trusted PXE boot method based on the requirements of classified protection standard was proposed to ensure the security and trust of the server's BIOS firmware,PXE bootfiles,and Linux system files.When the server performs PXE boot,TPCM measured BIOS firmware,BIOS boot environment measured PXE boot files,and PXE boot environment measured Linux system files.Taking TPCM as the root of trust,one level of measurement,one level of trust,and a chain of trust were established to achieve a trusted server operating environment.The proposed method was tested on a domestically-controlled,self-controllable Shenwei server.The experimental results show that the proposed method is feasible.…”

DMA-based key generation method for IoT scenario by Yinuo HAO, Zhou ZHONG, Xiaoli SUN, Liang JIN

“…Aiming at the problems of slow update frequency of channel key, low generation rate and limited node resources in the IoT scenario, a DMA-based physical layer key generation method was proposed, by using the agility and reconfigurability of DMA to improve the time variability and randomness of received signal.Firstly, DMA was used by the transmitter to randomly weight the signal and send it to the receiver, which could enhance the randomness of signals on the premise of ensuring the transparent reception of the signal.Then, the key from the received signal was extracted by the sender and receiver.By combining the rapid changeability and randomness of DMA, the randomness of signal source and the randomness of natural channel, a composite channel was constructed to improve the randomness of the key source.In addition, the channel estimation was transfered overhead from the terminal to the base station, which effectively reduced the overhead and delay of the communication system, and was suitable for IoT scenarios with asymmetric resources and lightweight equipment.Simulation results show that the proposed method can effectively improve the key generation rate in quasi-static scenarios, and the generated physical layer key has passed the NIST test.…”
