The concept of secrecy calls to mind a dyadic interaction: one person hiding a secret from another during a conversation or social interaction. The current work, however, demonstrates that this aspect of secrecy is rather rare. Taking a broader view of secrecy as the intent to conceal information, which only sometimes necessitates concealment, yields a new psychology of secrecy. Ten studies dem...

Motivated by typo correction in password authentication, we investigate cryptographic error-correction of secrets in settings where the distribution of secrets is a priori (approximately) known. We refer to this as the distribution-sensitive setting. We design a new secure sketch called the layer-hiding hash (LHH) that offers the best security to date. Roughly speaking, we show that LHH saves a...

We explicitly evaluate the generating functions for joint distributions of pairs of the permutation statistics inv, maj and ch over the symmetric group when both variables are set to −1. We give a combinatorial proof by means of a sign-reversing involution that specializing the variables to −1 in these bimahonian generating functions gives the number of two-colored permutations up to sign.

In light of these trends, this article offers an in-depth exploration of racial and ethnic achievement gap trends and a preliminary examination of different factors that may interact to influence the trends. It offers a comprehensive review of available data on the Black-White and Hispanic-White achievement gaps in reading and mathematics over the last three decades. The achievement gap is meas...

A multi-secret sharing scheme (MSS) allows a dealer to share multiple secrets among a set of participants. in such a way a multi-secret sharing scheme (MSS) allows a dealer to share multiple secrets among a set of participants, such that any authorized subset of participants can reconstruct the secrets. Up to now, existing MSSs either require too long shares for participants to be perfect secur...

competition law as a manifestation of economic public order has also extended its controlling shadow on the commercial interactions around intellectual properties. know-how as a specific and little-known example of such assets -at least in iranian law-, isn't apart from the rules of competition law. this research in comparative attitude and regarding the specifics of innovative confidentia...

In this paper, we focus our attention on the problem of assigning initial secrets to users in ad-hoc network (respectively, sensors in a sensor network) so that they can use those secrets to ensure authentication and privacy during their communication. The goal of this assignment is to ensure that any two users can communicate securely with each other even though each user maintains only a smal...
