A Novel Range Test
Boyd, Colin, Dawson, Edward, Okamoto, Eiji, & Peng, Kun (2006) A Novel Range Test. In Batten, L & Safavi-Naini, R (Eds.) Information Security and Privacy (LNCS 4058), 3 - 5 July 2006, Australia, Victoria, Melbourne.
In a range test, one party holds a ciphertext and needs to test whether the message encrypted in the ciphertext is within a certain interval range. In this paper, a range test protocol is proposed, where the party holding the ciphertext asks another party holding the private key of the encryption algorithm to help him. These two parties run the protocol to implement the test. The test returns TRUE if and only if the encrypted message is within the certain interval range. If the two parties do not conspire, no information about the encrypted message is revealed from the test except what can be deduced from the test result. Advantages of the new protocol over the existing related techniques are that it achieves correctness, soundness, °exibility, high e±ciency and privacy simultaneously.
