CCA-Secure Type-Based Proxy Re-Encryption Without Pairings
摘要
Abstract
Type-based proxy re-encryption is an effective and efficient cryptographic solution to ciphertext delegation and distribution, which also enables the ciphertext owners to carry out fine-grained delegation control. In this paper, we propose a new type-based proxy re-encryption scheme without pairings and prove it against the chosen-ciphertext attack (CCA) in the random oracle model. Compared with the existing type-based proxy re-encryption schemes constructed with pairings, our scheme owns better efficiency as well as the master key security.关键词
