A Ciphertext-Policy Attribute-Based Encryption Scheme with Constant Ciphertext Length [PDF]
, 2009 An Attribute-Based Encryption (ABE) is an encryption scheme, where users with some attributes can decrypt ciphertexts associated with these attributes. However, the length of the ciphertext depends on the number of attributes in previous ABE schemes.
