Abstract Attribute-based encryption is cryptographic techniques that provide
flexible data access control to encrypted data content in cloud storage. Each trusted
authority needs proper management and distribution of secret keys to the user’s to
only authorized user’s attributes. However existing schemes cannot be applied
multiple authority that supports only a single keywords search compare to multi
keywords search high computational burden or inefficient attribute’s revocation. In
this paper, a ciphertext policy attribute-based encryption (CP-ABE) scheme has
been proposed which focuses on multi-keyword search and attribute revocation by
new policy updating feathers under multiple authorities and central authority. The
data owner encrypts… More >
