Certificateless Authenticated Key Agreement Sample Clauses

Certificateless Authenticated Key Agreement. ‌ Certificateless public key cryptography shares many properties with identity-based cryp- tography. Both assume the existance of a trusted third party which holds a master key and do not use certificates as in traditional PKI. Moreover, CL-PKC, as ID-PKC, can use pairings to devise very efficient schemes with desirable properties. However, in the cer- tificateless setting, the KGC does not know the users’ private keys. Thus, certificateless cryptography offers better security over ID-PKC in many situations.
