Cleanup date March 2011 In cryptography , a system has provablesecurity if its security requirements can be stated formally in an adversary cryptography adversarial model, as opposed to heuristically, with clear assumptions that the adversary has access to the system as well as enough computational resources. The proof of security called a reduction is that these security requirements are met provided the assumptions about the adversary s access to the system are satisfied and some clearly stated assumptions about the computational hardness assumption hardness of certain computational tasks hold. An early example of such requirements and proof was given by Shafi Goldwasser Goldwasser and Silvio Micali Micali for semantic security and the construction based on the quadratic residuosity problem . There are several lines of research in provablesecurity. One is to establish the correct definition of security for a given, intuitively understood task. Another is to suggest constructions and proofs based on general assumptions as much as possible, for instance the existence of a one way function . A major open problem is to establish such proofs based on P NP, since the existence of one way functions is not known to follow from the P NP conjecture. Some proofs of the security are in given ... by an idealization. Exact security or concrete security is the name given to provablesecurity reductions where one quantifies security by computing precise bounds on computational effort, rather than an asymptotic bound which is guaranteed to hold for sufficiently large values of the security parameter .

In cryptography , concrete security or exact security is a practice oriented approach that aims to give more precise estimates of the computational complexities of Adversary cryptography adversarial tasks than Polynomial time reduction polynomial equivalence would allow. Traditionally, provablesecurity is asymptotic it classifies the hardness of computational problems using polynomial time reducibility. Secure schemes are defined to be those in which the advantage of any computational boundedness computationally bounded adversary is negligible function cryptography negligible . While such a theoretical guarantee is important, in practice one needs to know exactly how efficient a reduction is because of the need to instantiate the security parameter it is not enough to know that sufficiently large security parameters will do. An inefficient reduction results either in the success probability for the adversary or the resource requirement of the scheme being greater than desired. Concrete security parametrizes all the resources available to the adversary, such as running time and memory, and other resources specific to the system in question, such as the number of plaintexts it can obtain or the number of queries it can make to any oracle cryptography oracles available. Then the advantage of the adversary is upper bounded as a function of these resources and of the problem size. It is often possible to give a lower bound i.e, an adversarial strategy matching the upper bound, hence the name exact security. References Mihir Bellare M. Bellare , A. Desai, E.

are considered provablesecurity provably secure , as their semantic security can be reduced ...Semantic security is a widely used definition for security in an asymmetric key encryption algorithm . For a cryptosystem to be semantically secure, it must be infeasible for a computational complexity computationally bounded Adversary cryptography adversary to derive significant information about a message plaintext when given only its ciphertext and the corresponding public encryption key. Semantic security considers only the case of a passive attacker, i.e., one who generates and observes ciphertexts using the public key and plaintexts of her choice. Unlike other security definitions, semantic security does not consider the case of chosen ciphertext attack CCA , where an attacker is able to request the decryption of chosen ciphertexts, and many semantically secure encryption schemes are demonstrably insecure against chosen ciphertext attack. Consequently, semantic security is now considered an insufficient condition for securing a general purpose encryption scheme. The notion of semantic security was first put forward by Shafi Goldwasser Goldwasser and Silvio Micali Micali in 1982. ref name goldwasser micali 1982 Shafi Goldwasser S.

Goldwasser Micali subsequently demonstrated that semantic security is equivalent to the another definition of security called ciphertext indistinguishability . ref name goldwasser micali ...

orphan date May 2010 Presumed security is a principle in security engineering that a system is safe from attack due to an attacker assuming, on the basis of probability, that it is secure. Presumed security is the opposite of security through obscurity . A system relying on security through obscurity may have actual security vulnerabilities, but its owners or designers deliberately make the system more complex in the hope that attackers are unable to find a flaw. Conversely a system relying on presumed security makes no attempt to address its security flaws, which may be publicly known, but instead relies upon potential attackers simply assuming that the target is not worth attacking. The reasons for an attacker to make this assumption may range from personal risk the attacker believes the system ... believes the system owners have sufficient knowledge of security techniques to ensure no flaws exist, rendering an attack moot . Although this approach to security is implicitly understood by security professionals, it is rarely discussed or documented. The phrase presumed security appears to have been first coined by the security commentary website Zero Flaws ref http www.zeroflaws.net presumedsecurity Zero Flaws Presumed Security ref . The article uses the Royal Military Academy Sandhurst as an example, focusing on the apparent lack of entry security and contrasting it against the presumed security a military installation will have. The article also details the flaws inherent in a trust seal such as the Verisign Secure Site seal, and explains why this presumed security approach is actually detrimental to an overall security posture.

orphan date May 2010 nofootnotes date June 2009 Security convergence refers to the convergence of two historically distinct security functions &ndash physical security and information security &ndash within enterprises both are integral parts of any coherent risk management program. Security convergence is motivated by the recognition that corporate assets are increasingly information based. Whereas in the past physical assets demanded the bulk of protection efforts, today information assets demand equal if not far more attention. Convergence is endorsed by the three leading international organizations for security professionals &ndash American Society for Information Science and Technology ASIS , Information Systems Audit and Control Association ISACA and ISSA professional organization ISSA &ndash which together co founded the Alliance for Enterprise Security Risk Management to, in part, promote it.
