Signcryption [35] is a public key primitive that achieves the functionality of both an encryption scheme and a signature scheme simultaneously. It does this more efficiently than a...
Public key cryptography has been invented to overcome some key management problems in open networks. Although nearly all aspects of public key cryptography rely on the existence of...
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...
Public key encryption with keyword search (PEKS) enables user Alice to send a secret key TW to a server that will enable the server to locate all encrypted messages containing the...
In this work, we design a method for creating public key broadcast encryption systems. Our main technical innovation is based on a new “two equation” technique for revoking us...
