123btc
Mt. gox2, the operator of the world's largest bitcoin exchange, announced on 28 February that it had applied to Tokyo District Court for bankruptcy protection because 850000 bitcoins on the trading platform had been stolen
I have always trusted btc123. In 2013, I first found the fxbtc mainland platform on btc123 to buy bitcoin, and fxbtc collapsed and lost a lot of bitcoin. At that time, I thought that the mainland platform was not very reliable. Then I found mycoin on btc123, the Hong Kong platform. Considering that the legal system in Hong Kong is more perfect and btc123 is an endorsement, it should be safer. So I bought 2 million bitcoin from huocoin.com and transferred it to the multi currency treasure in mycoin platform for storage!!! Often login multi currency account, has been able to log in, and every day there is interest payment. In February of 2015, I happened to see the news that the boss of the platform ran the road and Hong Kong's capital took 3 billion yuan away!!! Then the mainland economic investigation called the police and refused to accept it. It said that the office address was in Hong Kong and asked me to call Hong Kong to report to the police. The Hong Kong police station received a call saying that I should report to the police in the mainland, and bitcoin did not accept the call to report to the police. Finally, it said that I could report to the police online first. I called the police on the Internet, no news!!! Now call the day should not, call the ground not work!!!! I hope the media, the government or the police can help me. I can't say that I have no hard-earned money for 15 years! I wonder if we can sue btc123 together? What else can we do to rece the loss? Thank you
I believe that the law will never let a bad man go.
According to the provisions of the Supreme People's Procuratorate and the Ministry of public security on the standards for prosecution of economic crime cases, those who illegally raise funds by means of fraud for the purpose of illegal possession shall be prosecuted under one of the following circumstances: 1. Indivial fund-raising fraud, the amount of which is more than 100000 yuan; 2; 2. Unit fund-raising fraud, the amount of more than 500000 yuan
report the illegal fund-raising companies to the economic investigation departments of public security organs. There are three ways to report the case:
1. Report the case directly to the public security organ
2. Report to the main regulatory authorities of various instries, for example, those involved in the banking instry can be reported to the CBRC, those involved in the securities instry can be reported to the CSRC, those involved in insurance can be reported to the CIRC, and those involved in financing guarantee companies and non financing guarantee companies can be reported to the provincial financial office or the provincial instrial and commercial bureau
3. Report to the "publicity platform for prevention and control of economic crimes"
extended information:
illegal fund-raising (according to the provisions of the notice on banning illegal financial institutions and illegal financial business activities) refers to the fact that units or indivials raise funds from the public by issuing stocks, bonds, lotteries, investment fund securities or other creditor's rights certificates without the approval of relevant departments in accordance with legal proceres, And promise to repay the principal and interest or give return to the investor in currency, material object and other ways within a certain period of time
according to the relevant provisions of the notice on further cracking down on illegal fund-raising activities (YF [1999] No. 289), "illegal fund-raising" can be summarized as follows:
(1) absorbing funds by issuing securities, membership cards or debt certificates
the more common ones are: issuing stocks, bonds, lottery tickets, investment funds and other rights certificates in disguise or in the name of futures trading and pawn. Illegal fund-raising by claiming shares, participating in dividends, entrusted investment and entrusted financial management. Through membership card, membership card, seat card, preferential card, consumption card and other ways of illegal fund-raising
(2) divide property, real estate and other assets equally, and raise funds with high interest by selling the disposal right of their shares
the latest change is: illegal fund-raising by selling its shares and committing to after-sale and leaseback, after-sale and buyback, regular rebate, etc recent changes: using underground banks to raise funds
the common ways are: illegal fund-raising by means of commodity sales and leaseback, buy back and transfer, development of members, merchant joining and "fast integration method" (6) illegal fund-raising in the form of pyramid selling or secret series (7) illegal fund-raising in the form of orchard or manor development for example, illegal fund-raising in the name of planting, breeding, project development, manor development, ecological and environmental protection investment (8) illegal fund-raising by means of "virtual" procts constructed by modern electronic network technology, such as "e-shop", "e-department store" investment entrustment, maturity repurchase, etc (9) illegal fund-raising in the form of Internet investment fund

Development process
Cryptography (in Western European languages, from Greek krypt) ó S "hidden", and gr á Writing is a subject that studies how to transmit information in secret. In modern times, especially the mathematical study of information and its transmission, it is often regarded as a branch of mathematics and computer science, and is also closely related to information theory
Ron Rivest, a famous cryptographer, explained: "cryptography is about how to communicate in the presence of enemies". From the perspective of engineering, this is equivalent to the similarities and differences between cryptography and pure mathematics. Cryptography is the core of information security and other related issues, such as authentication and access control. The primary purpose of cryptography is the meaning of hidden information, not the existence of hidden information
Cryptography also promotes computer science, especially the technologies used in computer and network security, such as access control and information confidentiality. Cryptography has been applied in daily life, including ATM chip card, computer user access password, e-commerce and so oncipher is an important means for communication parties to transform information according to the agreed rules. According to these rules, changing plaintext into ciphertext is called encryption transformation; Changing ciphertext into plaintext is called decryption transformation. In the early stage, cipher only added or decrypted words or numbers. With the development of communication technology, voice, image and data can be added or decrypted
Cryptography is graally developed in the practice of the struggle between coding and decoding, and with the application of advanced science and technology, it has become a comprehensive cutting-edge technology. It is closely related to linguistics, mathematics, electronics, acoustics, information theory, computer science and so on. Its practical research results, especially the cryptography and decoding methods currently used by governments all over the world, are highly confidentialthe rule of crypto transformation is called cryptosystem. The parameter indicating this transformation is called the key. They are an important part of cryptography
The basic types of cryptosystem can be divided into four types: disorderly according to the prescribed graphics and lines, changing the position of plaintext letters or numbers into ciphertext; Substitution -- one or more substitution tables are used to substitute plaintext letters or numbers for ciphertext; Cipher text: to change plaintext into ciphertext by using a pre-determined alphabetic or numeric cipher group instead of a certain phrase, word, etcscrambling-a series of sequences composed of finite elements are used as scrambling numbers, which are combined with plaintext sequences to form ciphertext according to the specified algorithm. The above four cryptosystems can be used alone or in combination to proce practical cryptosystems with high complexity
Since the 1970s, some scholars have proposed the public key system, which uses the mathematical principle of one-way function to realize the separation of encryption and decryption keys. The encryption key is public and the decryption key is confidential. This new cryptosystem has attracted the attention and discussion of cryptologyaccording to the rules of text and password, under certain conditions, various technical means are adopted to analyze the intercepted ciphertext, so as to obtain the plaintext and restore the cipher system, that is, to decipher the password. The requirements for decoding codes of different strength are different, even very different
In fact, secret letters were used in wars before BC. Herodotus, the father of western historiography, recorded some of the earliest secret letter stories in his history. In the 5th century BC, Greek city states had many conflicts and wars with Persia in order to fight against slavery and aggressionin 480 BC, Persia secretly assembled a powerful army to launch a surprise attack on Athens and Sparta
Demaratus, the Greek, saw the assembly in the city of Susa in Persia, covered the words on the board with a layer of wax, and sent it to the Greek to inform them of the plan of Persia. Finally, the Persian navy was lost in the Salamis Bay near Athenssince most people were illiterate in ancient times, the earliest form of secret writing only used paper and pen or equivalent items. With the improvement of literacy rate, real cryptography was needed. The two most classical encryption techniques are:
transposition cipher: rearrange the alphabetic order, such as' help me 'to' ehpl em '
substitution cipher: systematically changing a group of letters into other letters or symbols, such as' fly at once 'to' GMZ Bu podf '(each letter is replaced by the next letter)

research
as the main discipline of information security, cryptography of Xi'an University of electronic science and technology ranks first in China
In 1959, under the instruction of Qian Xuesen, Xi'an University of Electronic Science and technology took the lead in carrying out cryptography research in China. In 1988, Xidian was the first to set up a master's program in cryptography, and in 1993, it was approved to set up a doctor's program in cryptography. It is one of the first two doctor's programs in cryptography in China and the only doctor's program outside the military, And become the national 211 key construction disciplinein 2001, information security specialty was established on the basis of cryptography, which is the first batch of universities in China to set up this specialty
the information security major of Xi'an University of Electronic Science and technology relies on the first-class national key discipline "information and Communication Engineering" (the second in China) and the second-class national key discipline "cryptography" (the first in China), which is the innovation platform of 985 project advantage discipline and the key construction discipline of 211 project
State Key Laboratory of integrated service network theory and key technology, National Engineering Laboratory of wireless network security technology, modern switching and network coding research center (Chinese University of Hong Kong - Xi'an University of Electronic Science and Technology), Key Laboratory of computer network and information security, Ministry of ecation The Key Laboratory of the Ministry of ecation and other national, provincial and ministerial scientific research platforms
among the 34 directors of the Chinese society of cryptography, 12 are from Xidian, and the two vice directors are graates of Xidian. The only member of China in the international society of cryptography is also from Xidian. It is no exaggeration to say that Xidian has become the core base for training cryptography and information security talents in China
the following is a brief list of Xi'an Xin'an graates: Lai Xuejia, member of international cryptographic society, designer of idea block cipher algorithm; Chen Lidong, research fellow of American Bureau of standards; Ding Cunsheng, Professor, Hong Kong University of science and technology; Xing Chaoping, NTU Professor, Singapore; Feng Dengguo, director of the National Laboratory of information security, Chinese Academy of Sciences, and vice president of the Chinese cryptographic society
Zhang Huanguo, executive director of China cryptographic society, Professor of Wuhan University and leader of Xin'an; He Dake, vice president of China cryptographic society, Professor of Southwest Jiaotong University and leader of Xin'an; He Liangsheng, chief cryptographer of PLA General Staff; Ye Jiqing, director of key management center of PLA
Xi'an University of Electronic Science and technology has three Chinese leaders in the field of information security: Xiao Guozhen, Wang Yumin and Wang Xinmei. Among them, Professor Xiao Guozhen is one of the main pioneers of modern cryptography in China. His concept of statistical independence of combinatorial functions and his spectral characterization theorem of correlation immunity of combinatorial functions are internationally known as Xiao Massey theorem
has become one of the basic tools of cryptography research, and opened up a new field of stream cryptography research. He is a member of the Executive Committee of the Asian cryptographic society, vice chairman of the Chinese cryptographic society, and a consultant to the editorial board of the International Journal of information security (ijis)
in 2001, WAPI, the mandatory standard for wireless network security formulated by Xi'an University of Electronic Science and technology, shocked the world. China owns the completely independent intellectual property rights of the technology, breaking the monopoly of IEEE in the world. The Wall Street Journal reported at that time that "China's Encryption Standard for wireless technology caused confusion in the instry."
this technology is also one of the few significant scientific and technological advances that China has made in the IT field with world influence
the information security major of Xi'an University of Electronic Science and technology ranked first in China for many years, which is the best reflection of its leading position in the national information security field
