Abstract: Maintaining data confidentiality at the asymmetric-resource devices across emerging technologies needs varying cryptographic algorithms. Quantum computing makes preserving data confidentiality across asymmetric infrastructure more difficult. However, exploiting the architecture of classical cryptographic schemes to integrate the post-quantum constructs could be used to maintain post-quantum level confidentiality over the Internet. This paper presents a post-quantum secure classical ABE-IBE proxy re-encryption scheme (L ABE-IBE PRE) that utilizes the classical ABE-IBE proxy re-encryption capabilities at the end nodes in a system and raises the data confidentiality to post-quantum secure level over the Internet. The proposed L ABE-IBE PRE transforms a ciphertext of the classical ABE scheme to a post-quantum secure ciphertext and from a post-quantum secure ciphertext to a ciphertext of the classical IBE scheme. We compare our proposed L ABE-IBE PRE scheme with classical ABE-IBE proxy re -encryption schemes, including Encryption Switching ABE-IBE (ES.ABE-IBE) scheme (He et al., 2019). We discuss the security and efficiency of our proposed scheme. (More)
