Public Key Cryptography, also known as asymmetric cryptography, involves the use of two numerically related keys, a public key for encryption and a private key for decryption. It is the backbone of many forms of secure online communication and transactions including digital signatures, SSL/TLS, and cryptocurrency transactions.
To provide an example, one of the concrete use cases of this method is in HTTPS-enabled websites; the padlock before the website address in a browser’s address bar is proof that Public Key Cryptography is at work, ensuring secure communication between the user and the website.Background and History
The concept of Public Key Cryptography was first introduced in a 1976 paper by Whitfield Diffie and Martin Hellman. However, the first practical implementation was RSA (Rivest-Shamir-Adleman) algorithm developed in 1977. Since then, many other algorithms based on asymmetric encryption have been developed with greater performance and security features.
Functions and Use Cases
Public Key Cryptography serves several important functions in today’s digital world:
- Online Security: It allows secure exchange of data over insecure networks.
- Authentication: It can verify the sender’s identity and ensure data integrity.
- Digital signatures: It ensures the authenticity of digital documents.
- Cryptocurrency Transactions: It forms the underlying encryption mechanism in blockchains and cryptocurrencies.
