GenFedRL: a general federated reinforcement learning framework for deep reinforcement learning agents by Biao JIN, Yikang LI, Zhiqiang YAO, Yulin CHEN, Jinbo XIONG

“…To solve the problem that intelligent devices equipped with deep reinforcement learning agents lack effective security data sharing mechanisms in the intelligent Internet of things, a general federated reinforcement learning (GenFedRL) framework was proposed for deep reinforcement learning agents.The joint training through model-sharing technology was realized by GenFedRL without the need to share the local private data of deep reinforcement learning agents.Each agent device’s data and computing resources could be effectively used without disclosing the privacy of its private data.To cope with the complexity of the real communication environment and meet the need to accelerate the training speed, a model-sharing mechanism based on synchronization and parallel was designed for GenFedRL.Combined with the model structure characteristics of common deep reinforcement learning algorithms, general federated reinforcement learning algorithm suitable for single network structure and multi-network structure was designed based on the FedAvg algorithm, respectively.Then, the model sharing mechanism among agents with the same network structure was implemented to protect the private data of various agents better.Simulation experiments show that common deep reinforcement learning algorithms still perform well in GenFedRL even in the harsh communication environment where most data nodes cannot participate in training.…”

On Student Access and Equity in a Reforming University: by Kwesiga, Joy Constance

“…We argue that key to the reform programme was a reduction in the state's financial commitment in higher education and the implementation of alternative financial strategies especially relating to the introduction of the private sponsorship programme in 1992. Private sponsorship greatly expanded the intake of fee-paying students, and the total number of students in higher education in Uganda has ex panded enormously. …”

Provably secure secret sharing scheme based on bilinear maps by LI Hui-xian1, PANG Liao-jun2

“…A method to construct provable secure secret sharing scheme using bilinear pairing was recommended.Firstly,the semantic security definition for secret sharing scheme is given,which is developed from the standard definition of semantic security for the public key cryptosystems.Then,a new secret sharing scheme based on the bilinear maps is pro-posed,with its correctness,security and performance analyzed and proven subsequently.Compared with the existing schemes,the proposed scheme is provably secure.At the same time,the proposed scheme departs the private key compu-tation of participants from the secret distribution process and the dealer does not have to securely save each participant’s private key,which makes this scheme more secure and more efficient.Therefore,the proposed scheme is more applicable than the existing ones.…”
