With the rapid development of cloud technology and the huge amount of big data generation, outsourcing data storage to a cloud service provider is an efficient solution. The challenges on the trustworthiness of cloud providers are urgent to be solved due to many security and privacy violation incidents in recent years. Some enhanced data protection methods such as All-Or-Nothing Transformation (AONT) are proposed to provide additional protection on data security. However, the key management and access revocation operations will become a difficult task and the key manager will be vulnerable. In this paper, we propose to use the scalable consortium blockchain system to solve the key management for the AON-based data protection and outsourcing in the multi-clouds scenario. We propose a model that can provide secure data sharing through untrusted clouds with the key management provided by the consortium blockchain system as a service. We also provide practical case studies for using the novel AON data approaches to protect data security and tamper-proofing on key management.

Recently, Decentralized Digital-Asset Exchanges (DDAE) have received significant attention. This paper proposes six criteria to evaluate DDAE based on the Principles of Financial Market Infrastructure (PFMI), evaluate current DDAE systems with respect to two main protocols: inter-chain and exchange protocols. This paper introduces four inter-chain protocols and six exchange protocols, summarizes these protocols into several technical models and analyzes their characteristics. These analyses provide technical reference for the DDAE design in the future.

With the development of cloud computing, a large amount of sensitive data information is often stored on cloud servers in the form of ciphertext, thereby alleviating local storage pressure while ensuring data privacy. Although encryption helps protect the confidentiality of the data, a secure and efficient search of ciphertext data is a challenging issue. Aiming at the problems of searchable encryption schemes in the existing cloud environment, such as low search efficiency and accuracy, and poor security, this paper proposes a traceable, keyword searchable encryption scheme based on blockchain technology. This solution makes use of the advantages of the non-tampering and non-repudiation of the blockchain to store query records on the blockchain, thereby achieving traceability of user queries and preventing illegal users from leaking sensitive data. Finally, under the random oracle model, the scheme is proved to be adaptive and indistinguishable. Through comparative analysis, it is shown that the scheme has high search accuracy and security.

Blockchain is a shared database. The data or information stored in it has the characteristics of “unforgeable”, “full trace”, “traceable”, “open and transparent”, and “collective maintenance”. Based on these characteristics, blockchain technology has laid a solid foundation of “trust”, created a reliable “cooperation” mechanism, and has broad application prospects. This paper assesses opportunities and summarizes the related technologies of blockchain and its contribution to network security.

RSA encryption algorithm is widely used in information and communication systems to protect the security of information. But the protocol failure would bring a lot of risks to RSA encryption systems. In this paper, the security of RSA encryption system and detailed risks brought by protocol failure which is result of improper choices of parameters discussed. Furthermore, an at-tack scheme of these risks and corresponding pseudo-code are proposed in this paper. This attack scheme would provide warnings for designers and users of RSA encryption systems.

Product traceability is an effective technical solution to control and address product quality and safety issues, enabling consumers to fully know the full range of aspects of product flow. At present, the mainstream product traceability platform has the risk of system centralization, data being maliciously altered or destroyed. Blockchain can be effectively used in the supply chains to solve the above problems. The platform suitable for traceability system application based on Hyperledger Fabric was selected, designed a product traceability technical solution and a product traceability system solution prototype. The program content includes product traceability business requirements, architecture of traceability system, blockchain data storage scheme, transaction method and consensus mechanism, inquiry of traceability result etc. The platform of the product traceability blockchain based system in experimental environment is built and the query and verification process of the traceability on the blockchain traceability system is realized and tested, which proves the feasibility of the system.

In this paper, aiming at the shortcomings of the Artificial Bee Colony (ABC) algorithm in guiding bees and observing bees in the search mechanism, the author integrated the idea of self-regulation of antibody concentration in the immune algorithm, regarded the optimal solution as antigen, and the search bee as antibody for target search. In this paper, the differences between the optimal solution and the initial solution are compared by setting parameters when initializing the nectar source, so as to enhance the memory of antibodies, avoid falling into the local optimal when maintaining the diversity of the population, accelerate the convergence speed, and increase the global search ability of the algorithm. Simulation results of six classical test functions show that the proposed algorithm has obvious advantages over ABC algorithm in terms of optimization accuracy, convergence, accuracy and stability. We will combine the proposed algorithm with Blockchain techniques in our future work.

With the development of education informati-zation in China, the student profiles are becoming digitized. However, currently different digital profiles of a student are still stored dispersedly in multiple databases, which results in information silos and vulnerability to security and privacy threats. Aiming at these deficiencies, this paper proposes a secure storage and sharing scheme of student digital profile based on blockchain technology. With the characteristics of decentralization, security, credibility, and tamper-resistance of the blockchain, the consensus of network nodes is achieved through the Delegated Byzantine Fault Tolerance (DBFT) protocol, and the sharing of student digital profile information is achieved through the access control mechanism. The public information of educational digital information is preserved on the blockchain, and the student profiles are encrypted and stored in a database or cloud, which facilitates the effective storage of personal digital profiles and information sharing among various systems. The proposed scheme utilizes blockchain technology for decentralized and tamper-proof management, and provides a solution to information silos and security issues of student digital profiles.
