Cross-certification is the process that allows different Certificate Authorities (CAs) to recognize and trust each other's digital certificates. This enables users from one CA to communicate securely with users from another CA, facilitating interoperability in a diverse public key infrastructure (PKI) environment. By establishing a chain of trust between CAs, cross-certification enhances the overall security and usability of digital communications.
