Chaos-Based Symmetric Key Cryptosystems
Chaos theory is the study of dynamical systems that are highly sensitive to initial conditions and exhibit seemingly random behavior. From the perspective of cryptography and information security, randomness generated from entirely deterministic systems is a very appealing property. As such, the application of chaos in modern cryptography has been a topic of much research and debate for over a ...
متن کاملComparison of two Public Key Cryptosystems
Since the time public-key cryptography was introduced by Diffie andHellman in 1976, numerous public-key algorithms have been proposed. Some of thesealgorithms are insecure and the others that seem secure, many are impractical, eitherthey have too large keys or the cipher text they produce is much longer than theplaintext. This paper focuses on efficient implementation and analysis of two mostpo...
متن کاملKey-Insulated Public Key Cryptosystems
Cryptographic computations (decryption, signature generation, etc.) are often performed on a relatively insecure device (e.g., a mobile device or an Internet-connected host) which cannot be trusted to maintain secrecy of the private key. We propose and investigate the notion of key-insulated security whose goal is to minimize the damage caused by secret-key exposures. In our model, the secret k...
متن کاملMultivariable public-key cryptosystems
Recently Landau and Diffie gave in a series of articles in the Notices of the American Mathematical Society [DL02, Lan01, Lan00a, Lan00b] and in the American Mathematical Monthly [Lan04] excellent expositions on how the theory of multivariable polynomials are used in cryptography. However they covered only half of the story. They covered only the theory of polynomials in symmetric or secret cry...
متن کاملMultivariate Public Key Cryptosystems
As the title says, this book is about Multivariate cryptography. Besides code-, latticeand hash-based cryptosystems, Multivariate cryptography is one of the main fields of cryptosystems which are believed to be secure against attacks with quantum computers. Multivariate cryptography deals with systems of nonlinear polynomial equations in several variables over a finite field which are difficult...
