• If a Private Key Generator (PKG) is compromised, all messages protected over the entire lifetime of the public–private key pair used by that server are also compromised. This makes the PKG a high-value target to adversaries. To limit the exposure due to a compromised server, the master private-public key pair could be updated with a new independent key pair. However, this introduces a key-management problem where all users must have the most recent public key fo… Identity-based cryptography is a type of public-key cryptography in which a publicly known string representing an individual or organization is used as a public key.
