We know that in a general password system, the private key is randomly generated, and the public key is generated by the private key. In identity-based encryption, the user's private key is required to be generated if the user's public key (mailbox, etc.) is determined. To address this seemingly impossible requirement, identity-based encryption introduces a trusted third party, or institution called a key generation center, that owns a master key of the system that derives the private key corresponding to the public key (mailbox, etc.) based on the master key and the user's public key (mailbox, etc.) and distributes the private key to the user.

Johnwick.io found that hackers launched a denial-of-service (DoS) attack on a well-known wallet, Electrum server. Hackers used a botnet of more than 140,000 computers to attack Electrum's nodes and simultaneously deployed malicious nodes. When a user connects to these malicious nodes and sends a transaction using an older version of Electrum, the user is prompted to update the Backdoor Client. If the user installs the client as prompted, the private key is stolen and all digital assets are lost. Millions of dollars of digital currency have been stolen, according to Electrum officials. Devi Security Labs recommends that users of Electrum Wallet update to the latest version of the client via the official website and never use the link in the prompt message.

The root seed is entered into the HMAC-SHA512 algorithm to get a hash that can be used to create the master private key (m) and the master chain code. The primary private key (m) can then be born to correspond to the master public key (M) by using the normal elliptic curve m G process that we saw earlier in this chapter. Chain code is used to introduce entropy from the function that creates the child key in the master key. As shown in the following section.
