To implement secure communication on a company's intranet using public key and private key pairs, the most appropriate solution is to use a Certificate server.
A Certificate server is a software application that issues digital certificates for public keys. The server authenticates the identity of the certificate holder and verifies that the public key in the certificate belongs to that individual or organization. The private key is securely stored by the certificate holder and is used to decrypt messages that are encrypted using the public key.
By using a Certificate server, the company can create and manage its own digital certificates, which can be used to secure communication on its intranet. Each employee would have a unique digital certificate that contains their public key, which can be used by other employees to encrypt messages that only the certificate holder can decrypt using their private key. This ensures that only authorized personnel can access sensitive information, and that the data is protected against unauthorized interception and decryption.
Microsoft Internet Information Server (IIS) is a web server software application that can be used to host websites and web applications. While it does support Secure Sockets Layer (SSL) encryption, it is not specifically designed to issue and manage digital certificates.
A Virtual Private Network ( VPN) is a secure tunnel that allows remote users to access a private network over the public Internet. While it does provide secure communication, it is not specifically designed to use public key and private key pairs.
A File Transfer Protocol (FTP) server is a software application that is used to transfer files over the Internet. While it can support secure file transfers using SSL encryption, it is not specifically designed to use public key and private key pairs.
Therefore, the most appropriate solution to implement secure communication on a company's intranet using public key and private key pairs is to use a Certificate server.
