In this paper, we propose a novel privacy-preserving authentication scheme for EEG-based BCI systems, utilizing elliptic curve cryptography (ECC). Our scheme balances robust security with computational efficiency, making it suitable for resource-constrained environments. Since we are addressing security in a resource-constrained environment, such as EEG in BCI, we have constructed a lightweight authentication algorithm to meet the stringent requirements of minimal computational resources and energy consumption. The security analysis and performance evaluation of the authentication protocol show that our scheme is resistant to various attacks, such as replay, offline password guessing, privilege insider, user impersonation, and smart card stolen attacks. It offers mutual authentication and key agreement, requiring only 1632 bits of communication cost and 15.67139 ms of computational cost for the entire login authentication and key agreement phase.

By examining the efficacy of text corpora linked to agriculture for pretraining transformer-based language (TBL) models, this research delves into agricultural natural language processing (ANLP).

In such multi-requester and multi-task scenario, each task requester wants to protect the privacy of their own aggregation results. Thus, protecting privacies of both workers and task requesters pose a significant challenge for multi-task data aggregation. Most existing privacy-preserving data aggregation methods focus on single-requester scenarios. When applied to multi-task and multi-requester aggregation, existing methods are inefficient due to completing repeatedly each task and fail to safeguard the privacy of each task requester. Additionally, existing multi-task data aggregation schemes do not support multiple types of aggregation. To tackle these challenges, we propose PP-MAD, a multi-type and privacy-preserving multi-task data aggregation scheme based on blockchain for mobile crowdsensing. PP-MAD is able to aggregate multiple concurrent tasks from multiple task requesters, and it supports many types of data aggregation, including sum, mean, variance, weighted sum, weighted mean. Moreover, PP-MAD ensures privacies of workers’ data and aggregation results of each task requester, even under collusion attacks.

Additionally, the repeated use of cloned code can exacerbate vulnerabilities, increasing system fragility and maintenance costs, especially when synchronized modifications are required for cloned fragments during software evolution. To address these challenges, this paper proposes a privacy-preserving large-scale code fingerprint extraction model—Ringer. The model decouples feature extraction from clone detection, enabling efficient clone detection without direct access to the source code. Ringer employs syntax trees for lexical and syntactic analysis to comprehensively extract code features, and generates irreversible code fingerprints through token replacement and the Metro-128 hash algorithm, ensuring the privacy of the source code while effectively detecting clones. Experimental results show that Ringer performs excellently on datasets from multiple programming languages (e.g., Java, C++, Python, etc.), maintaining consistently high accuracy based on the characteristics of each language. On the Python dataset, Ringer achieves detection accuracies of 94%, 94%, and 97% for Type-1, Type-2, and Type-3 clones, respectively, further validating its efficiency and reliability in practical applications. Compared to mainstream detection tools (e.g., Moss and NiCad), Ringer outperforms in cross-language detection, demonstrating its robust adaptability and superior accuracy.
