Ciphertext-policy attribute-based encryption supporting access policy update and its extension with preserved attributes
Sign Up to like & getrecommendations! Published in 2017 at "International Journal of Information Security"
DOI: 10.1007/s10207-017-0388-7
Abstract: Attribute-based encryption (ABE) allows one-to-many encryption with static access control. In many occasions, the access control policy must be updated, but the original encryptor might be unavailable to re-encrypt the message, which makes it impractical.… read more here.
