We present a concrete scheme based on bilinear pairing, which enjoys the advantages of certificateless public key cryptography while providing the functionalities of proxy re-encryption. Moreover, the proposed scheme is unidirectional and compatible with current certificateless encryption deployments. Finally, we show that our scheme has chosen ciphertext security in the random oracle model. %G English %2 https://inria.hal.science/hal-01056377/document %2 https://inria.hal.science/hal-01056377/file/cms2010_submission_25.pdf %L hal-01056377 %U https://inria.hal.science/hal-01056377 %~ IFIP-LNCS %~ IFIP %~ IFIP-LNCS-6109 %~ IFIP-TC %~ IFIP-TC11 %~ IFIP-TC6 %~ IFIP-CMS %~ IFIP-2010
