Understanding the Threat Landscape for Public Key Infrastructure

The public key infrastructure (PKI) validates the trust between two entities for the secure exchange of data. Hackers compromise digital certificates, which are an essential part of this infrastructure, to perform malicious activities. A public key infrastructure (PKI) provides public-key encryption and digital signature services. It allows organizations to build a trustworthy networking environment by managing keys and certificates. The pair of public and private key form a critical part of PKI. In the SSL protocol, the public key is used to encrypt data and the private key is used to decrypt it.
