Slide 1: Welcome. Today we will discuss cryptography. Let’s consider two problems. In the first problem, you have a lot of data. 歡迎(大家). 今天, 我們會討論密碼學. 第一個: kǎolǜ Huānyíng (dàjiā). Jīntiān, wǒmen huì tǎolùn mìmǎ xué. Wǒmen lái liǎng gè wèntí. Dì yī gè: Nǐ yǒu hěnduō shùjù. Slide 2: Here is an example: you study biology and medicine and have a LOT of DNA data 比如說 1 bi ru shuo): bìng 1Zhè shì yīgè lìzi: Nǐ xuéxí shēngwù hé yīxué, yǒu hǎoduō hǎoduō de DNA shùjù. Almost everyone gives you their DNA data. You want to do some important calculations. You could save lives! zhòng wǎnjiù Chàbùduō, měi gèrénlèi gěi nǎi tāmen de DNA shùjù.
