Hash Algorithm) and convert to a new and more advanced computer data
encryption, according to the article “Security Cracked!” from New Scientist
. The reason for this change is that 41-years old associate professor
Wang Xiaoyun of Beijing's Tsinghua University and Shandong University
of Technology has already cracked SHA-1.
According to a Beijing digest, this SHA-1 encryption includes
the world's gold standard Message-Digest algorithm 5 (MD5). Before
Professor Wang cracked it, the MD5 could only be deciphered by today's
fastest supercomputer running codes for more than a million years.
However, professor Wang Xiaoyun, a graduate of Shandong
University of Technology's mathematics department, and her research
team obtained results by using ordinary personal computers.
In early 2005, Wang and her research team announced that they
had succeeded in cracking SHA-1. In addition to the U.S. government,
well known companies like Microsoft, Sun, Atmel, and others have also
announced that they will no longer be using SHA-1.
Two years ago, Wang convened an international data encryption
conference to announce that her team had successfully cracked the four
world-class standards of data encryption algorithms of MD5, HAVAL-1 28,
MD4 and RIPEMD within 10 years.
A few months later, she then cracked the even more advanced and difficult SHA-1.
