“…Blockchain is a new type of decentralized protocol that can securely store Bitcoin transactions or other data. The information cannot be forged or tampered with, and smart contracts can be automatically executed without the audit of any centralized organization [44,45]. Transactions can be digital currencies such as Bitcoin or digital assets such as debt, equity, copyright, etc.…”

The mushroom growth of IoT has been accompanied by the generation of massive amounts of data. Subject to the limited storage and computing capabilities of most IoT devices, a growing number of institutions and organizations outsource their data computing tasks to cloud servers to obtain efficient and accurate computation while avoiding the cost of local data computing. One of the most important challenges facing outsourcing computing is how to ensure the correctness of computation results. Linearly homomorphic proxy signature (LHPS) is a desirable solution to ensure the reliability of outsourcing computing in the case of authorized signing right. Blockchain has the characteristics of tamper-proof and traceability, and is a new technology to solve data security. However, as far as we know, constructions of LHPS have been few and far between. In addition, the existing LHPS scheme does not focus on homomorphic unforgeability and does not use blockchain technology. Herein, we improve the security model of the LHPS scheme, and the usual existential forgery and homomorphic existential forgery of two types of adversaries are considered. Under the new model, we present a blockchain-based LHPS scheme. The security analysis shows that under the adaptive chosen message attack, the unforgeability of the proposed scheme can be reduced to the CDH hard assumption, while achieving the usual and homomorphic existential unforgeability. Moreover, compared with the previous LHPS scheme, the performance analysis shows that our scheme has the same key size and comparable computational overhead, but has higher security.

“…As the underlying technology of the Bitcoin cryptocurrency system [38,39], blockchain is actually a distributed digital ledger. Each node in the blockchain system maintains the same backup of the entire ledger, and in subsequent developments, some nodes have emerged to keep only partial ledger blockchains, such as Stefano's scheme [40].…”

With the advantages of lightweight and high resource utilization, cloud-native technology with containers as the core is gradually becoming the mainstream technical architecture for information infrastructure. However, malware attacks such as Doki and Symbiote threaten the container runtime's security. Malware initiates various types of runtime anomalies based on process form (e.g., modifying the process of a container, and opening the external ports). Fortunately, dynamic monitoring mechanisms have proven to be a feasible solution for verifying the trusted state of containers at runtime. Nevertheless, the current routine dynamic monitoring mechanisms for baseline data protection are still based on strong security assumptions. As a result, the existing dynamic monitoring mechanism is still not practical enough. To ensure the trustworthiness of the baseline value data and, simultaneously, to achieve the integrity verification of the monitored process, we combine blockchain and trusted computing to propose a process integrity monitoring system named IPMS. Firstly, the hardware TPM 2.0 module is applied to construct a trusted security foundation for the integrity of the process code segment due to its tamper-proof feature. Then, design a new format for storing measurement logs, easily distinguishing files with the same name in different containers from log information. Meanwhile, the baseline value data is stored on the blockchain to avoid malicious damage. Finally, trusted computing technology is used to perform fine-grained integrity measurement and remote attestation of processes in a container, detect abnormal containers in time and control them. We have implemented a prototype system and performed extensive simulation experiments to test and analyze the functionality and performance of the PIMS. Experimental results show that PIMS can accurately and efficiently detect tampered processes with only 3.57% performance loss to the container.

Recent studies have shown that compared with traditional social networks, networks in which users socialize through interest recommendation have obvious homogeneity characteristics. Recommending topics of interest to users has become one of the main objectives of recommendation systems in such social networks, and the widespread data sparsity in such social networks has become the main problem faced by such recommendation systems. Particularly, in the oracle interest network, this problem is more difficult to solve because there are very few people who read and understand the Oracle. To address this problem, we propose an ant colony algorithm based recognition algorithm that can greatly expand the data in the oracle interest network and thus improve the efficiency of oracle interest network recommendation in this paper. Using the one-to-one correspondence between characters and translation in Oracle rubbings, the Oracle recognition problem is transformed into character matching problem, which can skip manual feature engineering experts, so as to realize efficient Oracle recognition. First, the coordinates of each character in the oracle bones are extracted. Then, the matching degree value of each oracle character corresponding to the translation of the oracle rubbings is assigned according to the coordinates. Finally, the maximum matching degree value of each character is searched using the improved ant colony algorithm, and the search result is the Chinese character corresponding to the oracle rubbings. In this paper, through experimental simulation, it is proved that this method is very effective when applied to the field of oracle recognition, and the recognition rate can approach 100% in some special oracle rubbings.
