In this paper, we discuss non-interactive updating of decryption keys in identity-based encryption (IBE). IBE is a public key cryptosystem where a public key is an arbitrary strin...

In Ciphertext-Policy Attribute-Based Encryption (CP-ABE), a user secret key is associated with a set of attributes, and the ciphertext is associated with an access policy over attr...
