Asymmetric Cryptography, also known as public-key cryptography, is a cryptographic system that employs a pair of mathematically related keys: a public key and a private key. Its primary purpose in crypto technology and institutional trading is to provide secure communication channels, digital signatures for data integrity and authentication, and key exchange mechanisms without requiring a prior shared secret. This system underpins the security models of most modern cryptographic protocols, including those supporting blockchain networks.
Mechanism
The operational logic dictates that data encrypted with a recipient’s public key can only be decrypted with their corresponding private key, ensuring confidentiality. Conversely, data signed with a sender’s private key can be verified using their public key, guaranteeing authenticity and non-repudiation of transactions or messages. These key pairs are computationally expensive to derive from one another, ensuring that knowledge of one key does not compromise the security of the other.
Methodology
The methodology relies on complex mathematical problems that are easy to compute in one direction but difficult to reverse without specific knowledge, such as integer factorization for RSA or discrete logarithms for ECC. In crypto investing and RFQ processes, this system provides a secure means for institutions to exchange sensitive information, verify the origin of trade requests, and confirm the integrity of smart contract interactions. Implementing robust key management practices, including secure storage and rotation of private keys, forms a critical component of its operational security.
