cloud computing promises a cost effective enabling technology to outsource storage and massively parallel computations. However, existing approaches for provably secure outsourcing of data and arbitrary computations are either based on tamper-proof hardware or fully homomorphic encryption. The former approaches are not scaleable, while the latter ones are currently not efficient enough to be used in practice. We propose an architecture and protocols that accumulate slow secure computations over time and provide the possibility to query them in parallel on demand by leveraging the benefits of cloud computing. In our approach, the user communicates with a resource-constrained Trusted cloud (either a private cloud or built from multiple secure hardware modules) which encrypts algorithms and data to be stored and later on queried in the powerful but untrusted Commodity cloud. We split our protocols such that the Trusted cloud performs security-critical precomputations in the setup phase, while the Commodity cloud computes the time-critical query in parallel under encryption in the query phase.

Problems related to privacy and cyber-attacks have increased in recent years as a result of the rapid development of cloud computing. This work concerns secure cloud computing services on a blockchain platform, called cloud@blockchain, which benefit from the anonymity and immutability of blockchain. Two functions- anonymous file sharing and inspections to find illegally uploaded files- on cloud@blockchain are designed. On cloud@blockchain, cloud users can access data through smart contracts, and recognize all users within the application layer. The performance of three architectures- a pure blockchain, a hybrid blockchain with cache and a traditional database in accessing data is analyzed. The results reveal the superiority of the hybrid blockchain with the cache over the pure blockchain and the traditional database, which it outperforms by 500% and 53.19% respectively.

In the field of Legal Metrology, it shall be assured that all measurements are carried out by a trusted computer system. Securing Computer Systems, especially in a distributed environment can be a challenging task to comply, since, in such an environment, a measurement instrument cannot be simply disconnected to guarantee its security. Following the approach of continuous monitoring to derive a normal system behavior can ensure continuous anomaly detection to satisfy the needed demands of Legal Metrology. The proposed Anomaly Detection approach measures the severity of the detected incident and places it into three different categories: green, yellow and red. The presented module can detect attacks against distributed applications in a cloud computing environment, using pattern recognition techniques for clustering, as well as statistical approaches. Both, inexperienced and experienced attacks have been tested and results are presented.

cloud computing systems, in which clients rent and share computing resources of third party platforms, have gained widespread use in recent years. Furthermore, cloud computing for mobile systems (i.e., systems in which the clients are mobile devices) have too been receiving considerable attention in technical literature. We propose a new method of delegating computations of resource-constrained mobile clients, in which multiple servers interact to construct an encrypted program known as garbled circuit. Next, using garbled inputs from a mobile client, another server executes this garbled circuit and returns the resulting garbled outputs. Our system assures privacy of the mobile client's data, even if the executing server chooses to collude with all but one of the other servers. We adapt the garbled circuit design of Beaver et al. and the secure multiparty computation protocol of Goldreich et al. for the purpose of building a secure cloud computing for mobile systems. Our method incorporates the novel use of the cryptographically secure pseudo random number generator of Blum et al. that enables the mobile client to efficiently retrieve the result of the computation, as well as to verify that the evaluator actually performed the computation. We analyze the server-side and client-side complexity of our system. Using real-world data, we evaluate our system for a privacy preserving search application that locates the nearest bank/ATM from the mobile client. We also measure the time taken to construct and evaluate the garbled circuit for varying number of servers, demonstrating the feasibility of our secure and verifiable cloud computing for mobile systems.

Efficient and secure MPC Through Integration of FHE and Proxy Re-encryption

secure multi-party computation (MPC) protocols play a crucial role in facilitating collaboration among distrustful parties while safeguarding individual privacy. Traditional MPC protocols rely on private communication channels and secret sharing schemes, which may not be feasible in scenarios with limited computational resources or intermittent connectivity. Fully Homomorphic Encryption (FHE) offers a promising solution, but its practical implementation for multi-party scenarios poses challenges such as huge storage complexity, interactive key generation, and decryption. In this work, we introduce the FHE-Pro scheme, which combines FHE with Proxy Re-encryption to address these challenges. Proxy re-encryption allows for secure delegation of decryption rights, enabling non-interactive key generation and decryption processes in MPC protocols. Our scheme offers a practical and efficient solution for secure multi-party computations, considering the specific requirements and constraints of diverse scenarios. © The Author(s), under exclusive licence to Springer Nature Singapore Pte Ltd. 2025.

A new scheme for securing users' data and applications in public clouds and data centers using Field Programmable Gate Arrays (FPGAs) has been developed. This scheme incorporates all necessary protocols, hardware, and software components to provide protection against many known potential attacks including internal attacks. It achieves perfect forward secrecy, provides FPGA authentication and integrity checks, and securely establishes a symmetric session key between the user and the FPGA. A complete prototype has been implemented to show the feasibility of the proposed scheme with current FPGAs. Experimental results showed that an FPGA-based compute node can be set up in a cloud in 3.36s;12.6 times faster than booting a medium-size conventional Virtual Machine (VM) on the same cloud. Based on the average global Internet speed, the time it takes to set up the FPGA-based machine from anywhere in the world was estimated to be 15s. Also, running an experimental secure image processing application on the FPGA took 50 percent less time than running the same application on a conventional state-of-the art processor (without a secure container).

Runtime Randomized Relocation of Crypto Libraries for Mitigating Cache Attacks

引用

IEEE ACCESS 2021年 9卷 108851-108860页

Crypto libraries such as OpenSSL and Libgcrypt are essential building blocks for implementing secure cloud services. Unfortunately, these libraries are subject to cache side-channel attacks, which are more devastating in cloud environments where inevitable cache contention among different tenants occurs. Previous approaches for mitigating cache side-channel attacks have limitations in terms of the deployability and security;these hinder utilization in cloud services. In this paper, we propose an R2-relocator, a novel library protection technique based on moving target defence. When injected into a running process, the R2-relocator performs randomized relocation of the library during runtime. By doing this, it transforms a vulnerable crypto library into one that randomly changes its memory (cache) location, thereby preventing the delivery of cache side-channel attacks against the library. The proposed technique achieves robust protection against cache side-channel attacks for all crypto libraries, even those containing unpatched critical vulnerabilities, without the need for reconfiguration of the library. Extensive evaluations of security, performance, and deployability of the R2-relocator demonstrate its effectiveness for secure cloud services.
