We present a system for sound modeling and synthesis that preserves the elegance and malleability of a sinusoidal model, while accommodating sounds with noisy (non-sinusoidal) components. We use an enhanced McAulay-Quatieri (MQ) style analysis that extracts bandwidth information in addition to the sinusoidal parameters for each partial. To produce noisy components, we synthesize with sine wave ...

We study ballot independence for election schemes: – We formally define ballot independence as a cryptographic game and prove that ballot secrecy implies ballot independence. – We introduce a notion of controlled malleability and show that it is sufficient for ballot independence. We also show that non-malleable ballots are sufficient, but not necessary, for ballot independence. – We prove that...

A malleable parallel task is one that can be executed on any number of processors, with its execution time being a function of the number of processors allotted to it. A nonmalleable parallel task is one that requires a speciic number of processors. Given n independent parallel tasks and m identical processors, we consider the problem of scheduling these tasks to minimize average completion tim...

It is tempting to think that if we encrypt a sequence of messages {xi} using a semantically secure encryption scheme, such that each xi is encrypted with its own independently generated public key pki, then even if the scheme is malleable (or homomorphic) then malleability is limited to acting on each xi independently. However, it is known that this is not the case, and in fact even non-local m...

With continuous growth in information aggregation and dissemination, studies on privacy preferences are important to understand what makes people reveal information about them. Previous studies have demonstrated that short-term gains and possible monetary rewards make people risk disclosing information. Given the malleability of privacy preferences and the ubiquitous monetary cues in daily live...

Identity-based encryption is a very convenient tool to avoid key management. Recipient-privacy is also a major concern nowadays. To combine both, anonymous identity-based encryption has been proposed. This paper extends this notion to stronger adversaries (the authority itself). We discuss this new notion, together with a new kind of non-malleability with respect to the identity, for several ex...

We consider the situation for public-key encryption that the adversary knows the randomness which was used to compute the ciphertext. In some practical scenarios, there is a possibility that the randomness is revealed. For example, the randomness used to make a ciphertext may be stored in insecure memory, or the pseudorandom generator may be corrupted. We first formalize the security notion on ...

We study ballot independence for election schemes. First, we formally define ballot independence as a cryptographic game and prove that ballot secrecy implies ballot independence. Secondly, we introduce a notion of controlled malleability and prove that it is sufficient for ballot independence. We also prove that non-malleable ballots are sufficient for ballot independence. Thirdly, we prove th...
