Description

[Technical Field]

[0001] This invention relates to a real-time evacuation and restoration type digital asset guard service provision system that protects digital assets (focusing on protecting not only from information leakage but also from information destruction) consisting of small amounts of data linked to important information such as personal information in real time from risks such as high-level cyber attacks that exceed normal levels, severe natural disasters, or physical attacks that are expected in the future. In this specification, "system" refers to a computer system that is configured by combining elements such as computers, other electronic devices, software, communication networks, and data, and that specifically realizes software-based information processing using hardware resources. [Background technology]

[0002] Conventionally, distributed encryption technology such as blockchain has been used as an example of a measure to protect data from common cyber attacks. However, in the future, we can expect to see more sophisticated cyberattacks (by state actors or actors combining state and non-state actors) that exceed the usual level, such as quantum computer-based cryptography and EMP attacks, which will be discussed later. These sophisticated cyberattacks aim to leak, alter, erase, or destroy digital assets (confidential information such as personal information and national security-related information, control modules for important functions, currencies such as stablecoins, digital currencies, and digital securities, and rights such as contracts). This makes it important to protect digital assets from high-level cyber attacks.

[0003] Digital assets subject to high levels of cyberattacks Digital assets that are subject to high-level cyber attacks are thought to cover a wide range of areas, including personal information (account information) and personal asset information held by financial institutions, confidential information such as personal information and national security-related information held by large corporations and government agencies, confidential internal information, important contracts and designs, control modules and data, and information related to lifelines.To date, there have been no services (especially for private use) that can provide a high degree of protection against high-level cyber attacks, and in fact, no services with quantum computer cryptanalysis resistance (such as PQC (Post-Quantum Cryptography)) have been put into practical use.

[0004] High-level cyber attacks High-level cyber attacks mainly include cryptographic analysis using quantum computers (often expressed as Y2Q (Years To Quantum)) and EMP attacks.

[0005] Quantum Cryptanalysis Cryptanalysis using quantum computers is a cyber attack that breaks through cryptographic guards, steals important information, and destroys systems by using SSL (Secure Sockets Layer) or blockchain public keys to decipher private keys and RSA cryptography. If quantum computers are misused, even if digital assets are protected by storing private keys in cold wallets separated from the system, there is a high risk that the private key will be decrypted using cryptanalysis performed on the public key. Cryptanalysis using quantum computers is a cyberattack that breaks through current basic security measures known as encryption. It is expected that combining various other attacks will lead to unexpected attacks with far-reaching impacts. Quantum computers are expected to be put into practical use around 2025, and with their improved performance, current general encryption methods are expected to be analyzed by around 2030. Furthermore, even if current cryptanalysis is difficult if important information is leaked, it is likely that such information will be analyzed by quantum computers in the near future. Therefore, it is important to make the information more resistant to quantum computer cryptanalysis than it is currently.

[0006] EMP attack An EMP attack is a cyberattack that uses strong electromagnetic waves generated by a nuclear explosion at high altitude (stratosphere) to destroy electronic devices, systems, and magnetically recorded digital assets. An EMP attack could destroy evacuated digital assets or the system modules that evacuate digital assets. Also, while not an EMP attack, large solar flares occur periodically. The strong magnetic field caused by these flares can cause physical destruction equal to or greater than that of an EMP attack. In recent years, analyses have been reported that if a large flare were to occur on the far side of the sun and be directed towards Earth, the damage that would result from a direct hit would be considerable. Furthermore, the risk of a Nankai Trough earthquake occurring by 2030 is becoming a concern in Japan. Data centers are concentrated in the Tokyo-Osaka area, which is within the expected damage range of such an earthquake, and so similar system destruction damage as described above is expected. Summary of the Invention [Problem to be solved by the invention]

[0007] Measures currently being considered against high-level cyber attacks Quantum cryptography is being researched as a countermeasure against cryptanalysis using quantum computers. However, considering the timing when quantum cryptography can be introduced to the general public and the cost of introducing quantum cryptography, it has not yet reached a practical level. Similarly, research is being conducted into the practical application of quantum computer cryptanalysis resistance (PQC (Post-Quantum Cryptography)), but it has not yet been put into practical use. Additionally, as a countermeasure against EMP attacks, data centers (including cloud computing) that meet US EMP resistance standards have implemented measures such as installing anti-magnetic mesh. However, only a portion of data centers in Japan have installed anti-magnetic mesh, or the measures do not meet sufficient standards. In terms of equipment destruction, there is a risk of the Nankai Trough earthquake in Japan, but the fact that approximately 90% of data centers are located in areas expected to be affected also poses a major risk.

[0008] In addition, using the cloud, it is possible to consider evacuating data to overseas regions (independent regions where data centers exist). However, the cloud poses risks, such as the risk of the cloud itself, the risk of the cloud backup itself being damaged, and the risk of insufficient user management, which has led financial institutions (especially large financial institutions) to refrain from using it. Specifically, most domestic cloud services are currently operated by overseas service providers, which means that if a problem occurs in Japan, they may be easily withdrawn, and contracts stipulate that lawsuits in the event of a problem will be held overseas. Furthermore, incorrect cloud configuration can create security holes that expose important information, or the system could be destroyed by a simple attack. Furthermore, even if you use a domestic cloud, if you only use one company's cloud to back up your digital assets, there is a risk that the backed up data will become unusable if a system failure occurs in the cloud.

[0009] In particular, measures to deal with cyber-attacks that simultaneously use quantum computer-based cryptanalysis, EMP attacks, and more advanced artificial intelligence are currently complex and costly, and have not yet reached a level at which they can be put to general practical use. In fact, even in light of current cases of cyber-attacks, there are limitations to how much can be done to counter cyber-attacks on the front end, and since in many cases attacks are actually initiated via human users, it is recognized that there are limitations to how much can be done to defend against cyber-attacks on the front end.

[0010] Other challenges Furthermore, when it comes to personal information, confidential corporate information, or state-level confidential information, the system is subject to very strict restrictions on the evacuation of digital assets. For example, if a business entity other than the individual manages digital assets, the individual's consent is required. However, in reality, it is difficult to obtain consent from the individual for all digital assets that may be subject to management. This makes digital asset management limited and complicated. Furthermore, when using cryptographic decentralization technology to evacuate digital assets, public and other blockchains cannot cut the chain that connects the blocks. Therefore, even if unnecessary data becomes junk and needs to be deleted or digital data needs to be erased for customer convenience, the digital data cannot be erased. Furthermore, because the block size is relatively small, it is not possible to record digital data exceeding the block size. Therefore, there is a limit to the amount of information that can be stored on a blockchain. Furthermore, it is impossible to manage personal information on a public chain. Furthermore, even if it were possible to create a function similar to the evacuation of digital assets using distributed ledger technology by combining public chains and freeware, the responsibility for public chains and freeware is unclear. It is undesirable to handle important or personal information with digital asset evacuation services that are fundamentally unguaranteed, given their reliability. While current attacks on blockchains involve the theft of private keys, in the future, cryptographic analysis of addresses will become the primary method. Therefore, even if technology is developed to defend against attacks that steal private keys on current blockchains, it is not reassuring.

[0011] Therefore, the inventors of the present invention have considered and examined measures to strongly and efficiently protect important information such as secret / classified information and personal information from high-level cyber attacks and physical destruction, and to restore important information without it being stolen by third parties even if it is subjected to cryptographic analysis by a quantum computer or an EMP attack, or measures to make it impossible for third parties to analyze the management information even if it is stolen by a third party.First, the inventors have considered and examined the preservation processing of backup data for internal systems, etc., which is carried out periodically in batches.

[0012] However, among the data that constitutes digital assets that need to be preserved, there is a huge amount of small-volume data linked to personal information. Unlike backup data held by corporate systems, small-volume data linked to personal information often requires real-time data preservation from the perspective of convenience (in the event of system destruction, in order to quickly restore the system, even a backup structure that allows for database-like processing is desirable, in other words, a function that realizes storage-like processing with data preservation functionality is desirable).

[0013] Furthermore, personal information is subject to strict legal regulations from the perspective of protection, and there is a strong need to further strengthen defenses against external cyber attacks in order to preserve small amounts of data linked to personal information.

[0014] Furthermore, there is a wide variety of data linked to personal information, and it is desirable to preserve the data in a variety of forms. Data linked to personal information in small units that do not exceed the block size can be saved to a blockchain, but as mentioned above, blockchains such as public chains cannot cut the chain that connects the blocks. When saving data to a blockchain, even if the data itself is subjected to a cyber attack, or as an application of this, information that exceeds the blockchain's block size is recorded in a distributed file function, with only the management information recorded on the block side, but even if this data itself is subjected to a cyber attack, it must be managed as meaningless data that is not recognized as personal information (including important information), and it must be made impossible to restore the original personal information as is.

[0015] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a real-time evacuation and restoration type digital asset guard service provision system that can preserve digital assets consisting of (basically) small amounts of data linked to personal information in real time, strongly and efficiently protect important information such as confidential information and personal information from high-level cyber attacks and physical destruction, and can restore important information without it being stolen by third parties even if it is subjected to cryptographic analysis using a quantum computer or an EMP attack, or can make it impossible for a third party to restore the management information even if it is stolen by a third party.
