In this paper, we define and explore proofs of retrievability (PORs). A POR scheme enables an archive or back-up service (prover) to produce a concise proof that a user (verifier...
Abstract. As the number of devices connected to the internet continues to grow rapidly and software systems are being increasingly deployed on the web, security and privacy have be...
The widespread use of public networks, such as the Internet, for the exchange of sensitive data, like legally valid documents and business transactions, poses severe security cons...
