Abstract Classical machine learning modeling demands considerable computing power for internal calculations and training with big data in a reasonable amount of time. In recent years, clouds provide services to facilitate this process, but it introduces new security threats breaches. Modern encryption techniques ensure are considered as the best option protect stored transit from an unauthorized third-party. However, decryption process is necessary when must be processed or analyzed, falling...

Internet-of-Things (IoT) environment has a dynamic nature with high risks of confidentiality, integrity, and availability violations. The loss information, denial access, information leakage, collusion, technical failures, data security breaches are difficult to predict anticipate in advance. These types nonstationarity one the main issues design reliable IoT infrastructure capable mitigating their consequences. It is not sufficient propose solutions for given scenario, but mechanisms adapt...

The residue number system (RNS) is an unconventional which can lead to parallel and fault-tolerant arithmetic operations.

Today, cloud technology continues to evolve. Using services allows you get financial benefitsio Still, many companies and users are in no hurry transfer their infrastructure the due incompletely resolved problems related security of data storage processing. Since case storing processing open data, a provider gets access an attacker can also gain by hacking account. In encrypted transmission cloud, confidentiality will be preserved only tasks, since require decryption task. The use...

Cloud technologies are widely used for storage services. However, the single cloud cannot ensure reliability of data. To solve security issue, we present a multi-cloud based architecture called WA-RRNS that combines weighted access scheme and threshold secret sharing redundant residue number system with multiple failure detection/recovery mechanisms homomorphic ciphers.
