With the rapid development of Internet of Things technology, security has become increasingly important since it collects a lot of personal information. IoT devices have resource constraints, which makes traditional cryptographic algorithms ineffective for IoT security. Lightweight cryptographic algorithms are needed to overcome the limitations of IoT devices. Due to its popularity and wide use in IoT applications, Raspberry Pi security plays an important role in Raspberry Pi applications. Analyzing existing works and understanding leading countries, keywords, authors, journals, and citations is crucial to identifying research trends and patterns in Raspberry Pi security. For the purpose of finding the information needed, bibliometric analysis was conducted using performance mapping, science mapping, and enrichment techniques. Our analysis included 979 Scopus articles, 214 WOS articles, and 144 IEEE Xplorer articles which were published during 2015-2023, and all of which were result of integrated and cleansed using the methods described in the methods section. By using R, VOS viewer, and the bibliometrix library, we analyzed and visualized bibliometric data. We discovered India is the leading research country, Archarya.B, and Bansod. G. are the most relevant authors, the Internet of Things, light-weight cryptography, and cryptography are the most relevant sets of words, and IEEE Access is the most significant journal. It was identified that developing a lightweight cryptographic algorithm for Raspberry Pi boards would be a significant future research focus.
