Why Information-Theoretic Security Sample Clauses

Why Information-Theoretic Security. Most of the currently used private key systems or public key schemes base their security on computational security. A cryptographic system is said to be computa- tionally secure if the amount of work to break such a system significantly exceeds the computational resources available to an adversary. For instance, if with the best known attacking method, the adversary still has to spend many years to break a system, even when assuming a constantly increasing computer speed, then we consider that system to be computationally secure. However, the current compu- tationally secure systems are not guaranteed to be secure in the future, since new, better attacking techniques may be developed to reduce the security level of the system. Contrary to computational security, information-theoretic security assumes no limit on the adversary’s computing resources. An information-theoretically se- cure system can be safe even if the adversary has unlimited computing power. Information-theoretic security is also called unconditional security. It is the stronger type of security model. In this thesis, we will study secret key agreement based on information-theoretic security. Secret key agreement is an important subject in cryptography. It deals with the problem how a secret key is generated and agreed to by two legitimate users. The traditional way to implement a secret key agreement is that a user encrypts a secret key with a public key cryptosystem, and then transmits it to the other user over a public channel. However, public key schemes are usually based on the assumption of intractability of some computational problem, for example factoring larger integers or taking discrete logarithms in some field. Hence, they are only computationally secure. On the other hand, it is shown in [71] that the two “intractable” problems mentioned above can be solved efficiently if quantum computers would come into being. That is why we are motivated to study secret key agreement based on information-theoretic security. On the other hand, we point out that systems based on information-theoretic security are less practical than those systems based on computational security like public key cryptosystems. For instance, no digital signature scheme is feasible with information-theoretic security. In the context of a large open network, public key infrastructure facilitates the key administration. However, the need to share secret keys between any two parties in the network implies that informa...

  • Product Information EPIZYME recognizes that by reason of, inter alia, EISAI’s status as an exclusive licensee in the EISAI Territory under this Agreement, EISAI has an interest in EPIZYME’s retention in confidence of certain information of EPIZYME. Accordingly, until the end of all Royalty Term(s) in the EISAI Territory, EPIZYME shall keep confidential, and not publish or otherwise disclose, and not use for any purpose other than to fulfill EPIZYME’s obligations, or exercise EPIZYME’s rights, hereunder any EPIZYME Know-How Controlled by EPIZYME or EPIZYME Collaboration Know-How, in each case that are primarily applicable to EZH2 or EZH2 Compounds (the “Product Information”), except to the extent (a) the Product Information is in the public domain through no fault of EPIZYME, (b) such disclosure or use is expressly permitted under Section 9.3, or (c) such disclosure or use is otherwise expressly permitted by the terms and conditions of this Agreement. For purposes of Section 9.3, each Party shall be deemed to be both the Disclosing Party and the Receiving Party with respect to Product Information. For clarification, the disclosure by EPIZYME to EISAI of Product Information shall not cause such Product Information to cease to be subject to the provisions of this Section 9.2 with respect to the use and disclosure of such Confidential Information by EPIZYME. In the event this Agreement is terminated pursuant to Article 12, this Section 9.2 shall have no continuing force or effect, but the Product Information, to the extent disclosed by EPIZYME to EISAI hereunder, shall continue to be Confidential Information of EPIZYME, subject to the terms of Sections 9.1 and 9.3 for purposes of the surviving provisions of this Agreement.
