"with the introduction of national laws such as the cybersecurity law and the cryptography law, our country's legal control over data security has become increasingly complete. however, there are many incidents of data leaks that can be verified in public information, indicating that the data security situation is still not optimistic." on august 29, at the "data security industry development" exchange event of the 2024 china international big data industry expo, xia luning, chief scientist and director of the research institute of beijing digital certification co., ltd., said.
"the value of data itself is released through its full circulation and sharing. if we simply focus on data security and treat it as a treasure, its value cannot be released, and the data itself has no value." xia luning said that between economic needs and the need to ensure data security, if we exclude data circulation and other factors, it is not difficult to simply achieve data security. we can build a data center that is isolated from the world and protected by layers of security, and keep it there forever, never use it, and prohibit anyone from accessing it. then the data security can be guaranteed to the vast majority.
"if this is the case, there is no point in us working on data security," xia luning said.
he believes that in the process of data fully circulating and realizing its value, risks will inevitably increase. data security must be guaranteed under the premise of data fully circulating and sharing. this squeeze from both sides has led to new challenges when we face various complex levels. one of the important things that has been continuously affected is digital trust.
"trust is the lubricant of society. a society without trust cannot function." xia luning said that trust is a prerequisite for any economic or even social behavior to function.
"a core idea of zero trust is called continuous authentication, which emphasizes continuous verification and dynamic policy adjustment." xia luning said that passwords have this basic nature.
he introduced that if traditional chinese medicine cryptography is used as identity, deep identity construction can be done through it. this is the definition of a password using a natural working fingerprint password.
"in the digital world, our identity is first of all a digital person; the digital technology of passwords, for the devices of digital life, and even the malicious purely digital system ai applications, their identities can also be authenticated by the same preposition." xia luning said that in the past we would establish a connection first and then look at the identity. before identity authentication, this service was transparent to you; now you have to indicate your identity first, then this connection and this service will be visible, and only then is it possible to take the next step.
xia luning believes that the behavior of the digital world is reflected in code, so code signing can certainly ensure that the code is in an original state, the state in which you originally allowed it to run.
