Also translated as “The whole is greater than the part,” this quote is about how much better things are together than as pieces. Mathematically, the whole is equal to the sum of its parts, neither more nor less. (ed.) 789–815. Third, the possibility to analyze the interaction between different subsystems of a metabolic network represents a promising avenue of further research in order to gain a better understanding of the intricate structure of metabolism.

This process is experimental and the keywords may be updated as the learning algorithm improves. CRYPTO 2013, Part I. LNCS, vol. If you say that something is more than the sum of its parts or greater than the sum of its parts, you mean that it is better than you would expect from the individual parts, because the way they combine adds a different quality. 2729, pp. Crypto (2016), Alkim, E., Ducas, L., Pöppelmann, T., Schwabe, P.: Post-quantum key exchange - a new hope.

When viewing a situation or a problem or challenge, it's always good to firstly step back by taking a helicopter view or a gestalt perspective of it. No, Aristotle Didn’t Write “A Whole is Greater Than the Sum of Its Parts” July 6, 2018 In: Menezes, A. The Whole is Less Than the Sum of Its Parts: Constructing More Efficient Lattice-Based AKEs. LNCS, vol. Aristotle needs revision: “The whole is (not always) greater than the sum of its parts.” Aware of this, we still itch to belong — to adhere — because we need to feel as though we are a part of something larger than our pitiable and soulless selves. 7428, pp. "The whole is greater than the sum of its parts." In: Oswald, E., Fischlin, M. LNCS, vol. Because AKE can be generically constructed by combining a digital signature scheme with public key encryption (or a KEM), most of these proposals focused on optimizing the known KEMs and left the authentication part to the generic combination with digital signatures. 6223, pp. (eds.) EUROCRYPT 2013. Psychological Gestalt theory would maintain that the whole is something else or something different than the sum of its parts. 122–140. LNCS, vol. The intuition is therefore that one can set the parameters of the scheme so as to not care about decryption errors and everything should still remain secure.

LNCS, vol. In: Public-Key Cryptography- PKC, pp. In: Boneh, D. In this mode, the signature size is doubled but this longer signature is enough to recover an even longer message – thus the signature is longer but the message does not need to be sent. The topic was academic freedom, and the impetus was the sudden “de-hiring” of Steven Salaita at the University of Illinois. 2612, pp. 7881, pp. LNCS, vol. When we pour our efforts into endeavors which make each other greater, offering our talents to benefit others, and produce things, ideas, and Springer, Heidelberg (2012), Micciancio, D., Regev, O.: Lattice-based cryptography. Our new AKE, which now remains secure in case of decryption errors, fails to create a shared key with probability around \(2^{-30}\), but adds enough security that we are able to instantiate a KEM based on the NTRU assumption with rings of smaller dimension. EUROCRYPT 2010. This service is more advanced with JavaScript available, SCN 2016: Security and Cryptography for Networks (eds.) 6110, pp. it does not depend on the structure of the message), and so it may be used in AKE constructions that use a different KEM, or even simply as a way to reduce the transmission length of a message and its digital signature.

We show that this naive solution is not quite correct, but the intuition can be made to work by a small change in the scheme. Our improvement uses particular properties of lattice-based encryption and signature schemes and consists of two parts – the first part increases security, whereas the second reduces communication complexity. PQCrypto 2014. It is also used by people looking for something somewhat cryptic to say to sound smart. In: Pointcheval, D., Johansson, T. (ed.) And a lot of people believed them, which isn't hard to understand, because if you don't have access to--or don't understand--the actual to . LNCS, vol. Not affiliated For some reason, many academics are better individually than when they aggregate: The academic whole is less than the sum of its individual parts. We first observe that parameters for lattice-based encryption schemes are always set so as to avoid decryption errors, since many observations by the adversary of such failures usually leads to him recovering the secret key. 2016 Aug 25;166(5):1078-1079. doi: 10.1016/j.cell.2016.08.011.

We show how this technique reduces the communication complexity of the generic construction of our AKE by around \(20\,\%\). Shooting whole-cell extract through a mass spectrometer only tells you the average metabolite content across all of the diverse and highly specialized cellular compartments. In this paper, we show that by simultaneously considering the secrecy and authenticity requirements of an AKE, we can construct a scheme that is more secure and with smaller communication complexity than a scheme created by a generic combination of a KEM with a signature scheme.

But since one of the requirements of an AKE is that it be forward-secure, the public key must change every time.
