Data Encryption at the Intersection of Mathematics and Physics: Comparing Physical Methods of Cryptography English | 2026 | ISBN: 3032247632 | 181 Pages | PDF EPUB (True) | 8 MB Data is becoming increasingly important, and so is data security. This book is aimed at anyone interested in high data security in telecommunications and data storage, especially IT security experts, procurers, decision-makers, consultants, and computer scientists. Anyone involved in procurement in this field makes decisions about algorithms, technologies, and providers, and thus also about infrastructure and security. The generation and distribution of keys for data encryption play a central role in this. Because security assessments for mathematical methods are based on assumptions, physical methods are becoming interesting in the high-security sector. They promise to link security more closely to the laws of nature. This raises the key question: Which technology is suitable for which application scenario, and what assumptions, costs, and operational risks are involved?  Data Analytics Toolkit: From Excel to Python, R, and Tableau English | 2026 | ISBN: 9780135397947 | 389 Pages | EPUB | 72 MB In today's data-driven business landscape, the ability to extract insights from information is no longer optional-it's essential. Yet many professionals find themselves trapped between the familiar comfort of spreadsheets and the untapped potential of more powerful analytics platforms.
