Certificateless Public Key Cryptography [PDF]
, 2003 This paper introduces and makes concrete the concept of certificateless public key cryptography (CL-PKC), a model for the use of public key cryptography which avoids the inherent escrow of identity-based cryptography and yet which does not require certificates to guarantee the authenticity of public keys. The lack of certificates and the presence of an

IET Information Security, Volume 2025, Issue 1, 2025.Public‐key authenticated encryption with keyword search (PAEKS) is a novel cryptographic primitive to resist against keyword‐guessing attacks (KGAs) and preserve the privacy of keywords in both ciphertexts and trapdoors. Recently, a designated‐server PAEKS (dPAEKS) scheme was proposed to withstand KGAs.
