Cryptology for Engineers: An Application-Oriented Mathematical Introduction

Cryptology is increasingly becoming one of the most essential topics of interest in everyday life. Digital communication happens by transferring data between at least two participants -- But do we want to disclose private information while executing a sensitive bank transfer? How about allowing third-party entities to eavesdrop on private calls while performing an important secret business discussion? Do we want to allow ambient communication concerning us to be manipulated while control software is driving our autonomous car along a steep slope? Questions like these make it clear why issues of security are a great concern in our increasingly augmented world.Cryptology for Engineers is a study of digital security in communications systems. The book covers the cryptographical functionalities of ciphering, hash generation, digital signature generation, key management and random number generation, with a clear sense of the mathematical background on the one hand and engineers' requirements on the other. Numerous examples computable by hand or with a small additional cost in most cases are provided inside.

密碼學正日益成為日常生活中最重要的話題之一。數字通信是通過至少兩個參與者之間的數據傳輸來實現的 - 但在執行敏感的銀行轉帳時，我們是否想要披露私人信息呢？在進行重要的商業秘密討論時，我們是否允許第三方機構竊聽私人通話？在控制軟件駕駛我們的自動車行駛在陡峭的斜坡上時，我們是否希望允許有關我們的環境通信被操縱？這些問題清楚地表明，安全問題在我們日益增強的世界中是一個重大關注點。《工程師的密碼學》是一本關於通信系統中數字安全的研究書籍。該書涵蓋了密碼學的功能，包括加密、哈希生成、數字簽名生成、密鑰管理和隨機數生成，一方面清楚地介紹了數學背景，另一方面滿足了工程師的需求。書中提供了許多手工計算或在大多數情況下僅需少量額外成本即可計算的示例。
