PKF is an acronym that stands for Public Key Framework. It refers to a cryptographic system that employs public key cryptography for securing communications and ensuring the authenticity and integrity of digital information.
Public Key Framework utilizes two different keys - a public key and a private key. The public key, as the name suggests, is openly distributed and can be accessed by anyone. It is used for encrypting messages and verifying digital signatures. Conversely, the private key is known only to the owner and is kept confidential. It is employed for decrypting messages and creating digital signatures.
In the PKF, the public and private keys are mathematically related, but it is computationally infeasible to derive the private key from the public key. This property ensures the security of the system and allows for secure communication over insecure channels, such as the internet.
The PKF has numerous applications, including secure email communication, digital signatures, and secure online transactions. It provides a robust and trusted mechanism for ensuring confidentiality, authentication, and non-repudiation in various digital communication scenarios.
Overall, the Public Key Framework (PKF) is a cryptographic system based on public key cryptography, offering a secure way to protect digital information and ensure the integrity and authenticity of data exchanged in electronic communications.
