This week, Lunaray will certainly even more exchange with you regarding the threats and defense strategies related to blockchain cryptography security.
Now that we have actually seen the 3 main attack techniques against cryptography protection, after that what are the major threats to cryptography security?
Blockchain cryptography safety analysis:
(1 Exclusive essential administration approach threats
The safety and security of exclusive essential management is the premise of blockchain cryptography safety. The current mainstream means is to manage it through software and equipment wallets, or to be kept by users themselves.
As soon as the exclusive key is shed, the user is not just not able to carry out any kind of procedures on the information, however likewise incapable to use and get the electronic possessions they possess, leading to permanent losses.
(2 There are backdoors and technicalities in the engineering technique of cryptographic formulas
Cryptography has actually established to a substantial maturity, and cryptographic algorithms such as ECC and RSA have themselves been mathematically verified to have a high level of security.
Nevertheless, because of the intricacy of its algorithms, there are backdoors and susceptabilities in design technique. Attackers typically use these susceptabilities to swipe the private key.
What should we do concerning these risks?
(1 Make use of a selection of storage methods to protect the private key
There are usually three sorts of protected storage space techniques for the personal trick, hardware storage space, software storage space, and split storage. Selecting the suitable storage technique can properly strengthen the security of the personal secret.
1 、 Hardware storage, the personal key is stored in an equipment security card or USBKey, the usage procedure normally consists of two kinds:
a)Store the personal type in the card, export the personal key to the blockchain client software program pocketbook when made use of, and delete the exterior personal secret after use; b)The private key continues the signature computation straight in the equipment card, the packaged purchase result, the exclusive key does not leave the hardware device during the entire use procedure.
Compared with both techniques, the cost of a is reduced, and the corresponding functions can be completed by using a USB disk.
The security of b is greater, and the price of use is higher. The exclusive essential execution environment ensures the protection of the entire operating environment in the equipment, and the exclusive trick can not be stolen by Trojan infections.
2 、 Software storage space, which is the most commonly used approach in the blockchain system currently, is to establish the password, use the password and then secure the private secret to store in the software application customer.
It is very simple to use and inexpensive, but the safety is very low compared with the equipment.
3 、 Split storage space, this method splits the original exclusive trick right into 2 to n parts, stores each exclusive essential component independently in various areas or users.
And when it is required to be made use of, it is manufactured and signed by specific mathematical methods, so regarding stay clear of the leak of the whole exclusive empire, and the leakage of part of the personal secret will certainly not impact the security of the entire asset.
This approach is much more protected, yet it is more made complex to utilize. One of the most typical example is the limit signature system, which is presently frequently used in blockchain systems to secure huge possession purchases.
(2 Use PKI digital certificate management and CA qualification
PKI (Public Key Facilities) is a standards-compliant innovation and spec that utilizes Public Trick encryption innovation to supply a safe and secure facilities for shopping.
Through a third-party relied on company– the accreditation facility CA (Certicate Authority), the individual’s public secret and the customer’s other identification info (such as name, e-mail, ID number, and so on) are packed together to validate the identity of the individual on the net. The electronic certification based upon the PKI structure to encrypt the electronic information to make certain the discretion and stability of info transmission.
