Organizer: Christian Janson, TU Darmstadt, Cryptoplexity Group
This is the fourth talk in the seminar series „Reading the Crypto Classics“ for the summer term 2021. The idea of this seminar is to jointly read classical milestone papers in the area of cryptography, to discuss their impact and understand their relevance for current research areas. The seminar is running as an Oberseminar, but at the same time meant to be a joint reading group seminar of the CROSSING Special Interest Group on Advanced Cryptography with all interested CROSSING members being invited to participate.
This issue will cover the paper
Al-Riyami, Paterson: „Certificateless Public Key Cryptography“ (ASIACRYPT 2003); available at https://doi.org/10.1007/978-3-540-40061-5_29
with the following abstract:
„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 adversary who has access to a master key necessitates the careful development of a new security model. We focus on certificateless public key encryption (CL-PKE), showing that a concrete pairing-based CL-PKE scheme is secure provided that an underlying problem closely related to the Bilinear Diffie-Hellman Problem is hard.“
