The evening breeze blew across the river, the microwave sparkled, and the night gradually deepened. At this time, the young child was already asleep, and it was time for a mother, Dai Yue, to wear a star under the shining starlight. The bright starlight lit up the night, and she awakened the American government.
First, there are accidents and inevitability.
1966, a baby was quietly born in Zhucheng, which is known as "the capital of Shun Di". No one knows that a legend is about to be born. She is the Wang Xiaoyun who once brought down the American government. Her name is simple and easy to write, but her brain is not simple at all!
Wang Xiaoyun's father graduated from Zhucheng Normal School majoring in mathematics and chemistry. Her interest in mathematics originated from her father, and she likes to think and study problems since she was a child, so her grades in science are better than those in liberal arts. In the senior high school entrance examination, she only studied for 40 days and was successfully admitted to Zhucheng No.1 Middle School. This made her realize her learning potential, so she began to work hard and started the road of self-exploration. This is a long road, and I will go up and down.
His mother's words and deeds still affect Wang Xiaoyun. In order to let the children concentrate on their studies, and because the father often teaches outside and doesn't come back often, Wang Xiaoyun's mother undertakes all farm work and housework alone, and also takes care of education to accompany the children. When the children were in trouble, the mother said that the Prime Minister could have a boat in his stomach and told the children to avoid extravagance and recklessness. If they are poor, they will be immune to it. If they are rich, they will help the world. Doing science requires not only brain power, but also temperament and quality.
Turing Prize winner Yao Qizhi commented on her, "She has an intuition that she can pick out the best path from thousands of possibilities." This is not only admiration and admiration for her talent and inspiration, but also high recognition and appreciation for her achievements, as if it was destined to be her, and it must be her, to solve the most difficult secret.
Einstein, a famous physicist, said: There is no such thing as luck, even the most accidental accidents are inevitable. Choosing cryptography is an accident for Wang Xiaoyun, but her solid professional foundation, ten years' interest and unremitting efforts are the inevitability of her success.
Second, "Workaholic" Wang Xiaoyun
In the first issue of Everybody Talk, Wang Xiaoyun told a little joke of her own as a guest. He has a younger brother who studies mathematics. He asked Wang Xiaoyun, why do you girls do such a good job in password analysis? Is it because you girls are naturally interested in personal privacy? This "self-deprecating" joke made me laugh, and she was embarrassed to laugh herself. I can't help thinking that she is really a modern Mulan, cheerful and informal.
In her spare time, she will leave her time for her own interests. One of her "interests" is to mop the floor, the wooden floor at home, two or three times a day. I think she just changed her posture and kept thinking about solving the problem, otherwise she wouldn't like mopping the floor so much. There are also flowers and stamp collecting markets. From the interest, we can know that Wang Xiaoyun turned a deaf ear to what happened outside the window and only decrypted it. She is an enduring person who has been accompanied by difficult passwords for decades.
There is a legend that Wang Xiaoyun had the idea of cracking the White House code when he gave birth to a child and was confined to the moon. Later, after her personal confirmation, it turned out to be true. It can be seen that breaking the secret is something that she has never stopped as a newborn mother. It must be a wonderful thing to have a career dream with you all your life.
Three or ten years to decipher the White House code.
Wang Xiaoyun came into contact with hash function when he was a doctor, and applied to the national administrative department for a project to study hash function. Unexpectedly, this hopeless project received strong support, so she began a long road to crack the White House password.
The research conditions at that time were hard and crude. In order to devote more time to research, she spent all the money at home, bought a computer, a laser printer and a scanner at her own expense, and started her daily life of looking after children and typing codes. Of course, the premise of all this is the husband's full support.
Because it was recognized as the safest cryptographic algorithm in the world at that time, she said that she didn't want to crack it at first, so she only analyzed its security at that time. I didn't expect a crack plan. Ten years later, she finally ushered in the successful cracking of MD5 and SHA- 1 in 2005.
There is persistence and persistence behind every legend. Every time her description of deciphering is fleeting, but scientific inquiry is never easy. When she was cracking the White House password, she met a problem that almost broke her down. However, her unyielding personality did not make her give up. She is the most secure password in the world, and it will only be more "stubborn".
Fourth, the joy of breaking the secret.
Once someone asked Wang Xiaoyun, what was your mood after you cracked MD5? She said I was happy every time I finished cracking it. I have a best friend who tells her every time I crack it. She will be happy with me, and I will tell my lover.
Sharing is her way of celebrating, celebrating great miracles in an ordinary way. Madame Curie said: scientific discussion and research itself contains the ultimate beauty, and its own happiness is the reward. Yes, her achievement is a reward from heaven, a reward from the heart, which is enough and does not need a shiny vanity label.
In 2004, Wang Xiaoyun went to the American Secret Society and tested the method of cracking the MD5 algorithm on the spot. As the host of the conference at that time, Biham said: Congratulations, you cracked MD5! The audience gave thunderous applause. A cryptographer was injured in the arm, and he even slapped his thigh with his other hand to show his applause. It can be seen that the cracking of MD5 is sensational!
Later, the National Institute of Standards and Technology (NIST) publicly vowed: "Although MD5 has been cracked, SHA- 1 has not found any security risks." In order to win a sigh of relief, Wang Xiaoyun began to crack the password SHA- 1, which is widely used in the world, and cracked the password that the United States thinks is the safest.
Five, for the past and the future, for eternal peace.
Someone asked: What's the difference between a cryptographer and a hacker? Sa Beining, the host, quipped that it was like asking historians why they didn't rob tombs. Wang Xiaoyun replied that the purpose of hackers is different. The purpose of hackers is to break the ring and make everyone unsafe. Our task is to make hackers have no choice, ensure everyone's information security, including the national information security, and build a secure information system.
Science is for the people. Intellectuals in society must be people with conscience, so that knowledge is meaningful and so is science. She also participated in the design of China's Hash function SM3, which is widely used in finance, transportation, state grid and other industries, emphasizing the need to establish an overall national security concept and improve national security defense capabilities. At the same time, she undertook and completed a number of key projects in China, making great contributions to protecting people's network information security.
Not only "open peace for the world", but also "a lesson from the past." Wang Xiaoyun is both a professor and a teacher. In order to stick to the front-line work, she came to Beijing and worked in Tsinghua, and her focus gradually shifted to personnel training. She tells her students not to do anything or do their best, and she often cares about greeting her students every day.
In front of students, she is not only a strict teacher, but also a loving mother. It not only mastered the unique skills of developing to the highest level, but also passed them on to the next generation of young people, training cryptographers for the country. Hard-working gardeners always cultivate the most brilliant flowers in the motherland.
It was another dark night, and silver was sprinkled on the window. It's just that everything is silent. The breeze and the frivolity of the sky make people yearn for the darkest and brightest sky. There is a deep desire, a thirst for knowledge and a thirst for exploration, which is the consistent mission of Academician Wang Xiaoyun's life.
