Suppose a | b ‚ so that b = at for some t ‚ and b | c‚ so that c = bs for some s. Then substituting the first equation into the second‚ we obtain c = (at)s = a(ts). This means that a | c‚ as desired. 6. Under the hypotheses‚ we have c = as and d = bt for some s and t . Multiplying

Message-Locked Encryption and Secure Deduplication Mihir Bellare1 Sriram Keelveedhi2 Thomas Ristenpart3 March 2013 Abstract We formalize a new cryptographic primitive‚ Message-Locked Encryption (MLE)‚ where the key under which encryption and decryption are performed is itself derived from the message. MLE provides a way to achieve secure deduplication (space-efficient secure outsourced
