چکیده
Suppose Alice sends an encrypted message to Bob c = Ek(m), where m is the plaintext message, c is the ciphertext and E is the encryption with respect to key k. If an eavesdropper Eve intercepts the message, knowing the encryption and decryption schemes but not the key, how much can Eve learn about m? We formalize this using two measures of security: indistinguishability of encryptions and semantic security.

Investigation of Game Between Cells in Occurrence of Genetic Mutations Using Evolutionary Game Theory
In this paper, two games that play a role in creating a cancer tumor and suppression are studied using evolutionary game theory and its different modes are analyzed. The first game is the competition between a cancer cell and a healthy cell to receive food through the blood. In the second game, the interaction between the two oncogenes Ras and Myc is examined for cellular deformation
متن کاملCooperative network flow problem with pricing decisions and allocation of benefits: A game theory approach
Several real problems in telecommunication, transportation, and distribution industries can be well analyzed by network flow models. In revenue management, pricing plays a primary role which increases the profit generated from a limited supply of assets. Pricing decision directly affects the amount of service or product demand. Hence, in traditional maximum flow problem, we assume that the dema...
متن کاملMonotonic core solutions: beyond Young's theorem
We introduce two new monotonicity properties for core concepts: singlevalued solution concepts that always select a core allocation whenever the game is balanced (has a nonempty core). We present one result of impossibility for one of the properties and we pose several open questions for the second property. The open questions arise because the most important core concepts (the nucleolus and th...
متن کاملA game theory approach to the sawnwood and pulpwood markets in the north of Iran
Duopoly game theory is applied to the wood industrial markets (sawnwood and pulpwood markets) in the North of Iran. The Nash equilibrium and the dynamic properties of the system based on marginal adjustments are determined. The probability that the Nash equilibrium will be reached is almost zero. The dynamical properties of sawnwood and pulpwood prices derived via the duopoly game model are fou...
متن کاملMulti-objective Modeling Based on Competition Airlines Cooperation by Game Theory and Sustainable Development Approach
In each time period, the demand of passengers for each route are finite and airlines compete for earning more profits. The complex competition among airlines causes problems, such as complicating flight planning and increasing empty seats for some routes. These problems increase air pollution and fuel consumption. To solve these problems, this research studies the cooperation of the airlines wi...
