On Constructing Certificateless Cryptosystems from Identity Based Encryption [chapter]

Benoît Libert, Jean-Jacques Quisquater
2006 Lecture Notes in Computer Science  
Certificateless cryptography (CL-PKC) is a concept that aims at enjoying the advantages of identity based cryptography without suffering from its inherent key escrow.  ...  Several methods were recently suggested to generically construct a certificateless encryption (CLE) scheme by combining identity based schemes with ordinary public key cryptosystems.  ...  A subsequent work of Yum and Lee considered the relations between identity-based (IBE), certificate based (CBE) and certificateless encryption schemes (CLE) and established a result of essential equivalence  ...
