چکیده
Terahertz (THz) nondestructive testing has emerged as a promising tool for public security check due to its superior detection accuracy and sensitivity hidden objects under clothing. However, it is unknown if material composition textile structure of clothing will influence the THz spectrum objects. In this paper, time domain spectroscopy (THz-TDS) was used detect several natural artificial fabrics containing pure amino acids with characteristic absorption peaks between 0.2 1.6 THz. The results show that AAs various cloth materials have different degrees decrease redshift. addition, disappear when destroyed. Moreover, simulation also verify an obvious effect on field distribution. sense, necessary analyze detecting using signal.

توابع درهم نقش بسیار مهم در سیستم های رمزنگاری و پروتکل های امنیتی دارند. در سیستم های رمزنگاری برای دستیابی به احراز درستی و اصالت داده دو روش مورد استفاده قرار می گیرند که عبارتند از توابع رمزنگاری کلیددار و توابع درهم ساز. توابع درهم ساز، توابعی هستند که هر متن با طول دلخواه را به دنباله ای با طول ثابت تبدیل می کنند. از جمله پرکاربردترین و معروف ترین توابع درهم می توان توابع درهم ساز md4, md...
