An Authenticated Notification refers to a digital message or alert whose origin and integrity are cryptographically verified. Within crypto systems, its purpose is to assure recipients that critical information, such as trade confirmations or price updates, genuinely originates from a trusted source. This verification also confirms that the message content has not been tampered with during transmission, essential for secure financial operations.
Mechanism
This typically involves the sender digitally signing the notification content using their private key. The recipient then utilizes the sender’s public key to verify the signature, confirming both the sender’s identity and that the message content remains unaltered since signing. Standard cryptographic algorithms, often used in blockchain transactions, facilitate this process.
Methodology
The core approach relies on established public-key cryptography principles to establish trust in data transmission. Implementation necessitates robust key management, secure storage of private keys, and a reliable public key infrastructure. System design must account for message replay protection and timely revocation of compromised keys to maintain continuous security assurances.
