Collusion-free protocols are impossible to achieve (in general) when all parties are connected by point-to-point channels, but

Soil Organic Matter Characterization,h does not get any information on the secret. Similar to secret-sharing schemes for general access structures, there are gaps between the known lower bounds and upper bounds on the share size for graphs. Motivated by the question of what makes a graph “hard” for secret-sharing schemes, we study very

Soil Organic Matter Characterization, credentials may change and ciphertexts may be stored by a third party. Our main result is obtained by pairing two contributions:.We then combine these two results for a new approach for revocation on stored data. Our scheme allows a storage server to update stored ciphertexts to disqualify revoked

Organic Matter and Soil Quality, the input of the sender. Hiding the size of the input of a player is a critical requirement in some applications, and relatively few works have considered it. Notable exceptions are the work on zero-knowledge sets introduced in [.], and recent work on size-hiding private set intersection [.]. Howev

Global Change - The IGBP Serieschannel from sender to adversary is “noisier” than the channel from sender to receiver. It has developed in the Information and Coding (I&C) community over the last 30 years largely divorced from the parallel development of modern cryptography. This paper aims to bridge the gap with a cryptographic
