Contact Tracing in Post-Covid World: A Cryptologic Approach
暫譯: 後疫情時代的接觸追蹤：密碼學方法

本書是有關接觸追蹤應用領域的最新技術的及時文獻。這一主題在醫學科學領域中廣為人知，最近因為 COVID-19 疫情而受到政府、產業和學術界的關注。本書提供了與接觸追蹤應用相關的新提案與主要從密碼學觀點出發的文獻回顧之間的連結。由於這些應用涉及個人的安全與隱私，從密碼學的角度分析它們至關重要。因此，本書討論了來自全球各地（包括新加坡、歐洲、美國、澳洲和印度）大多數提案的密碼學方面的最新發展。對每個協議的設計原則進行深入研究，本書對研究人員、學生和專業人士都具有價值。
