Há 11 horas · In fact, to tie back to Bill Casselman's column, experts at agencies like NIST recommend using elliptic curves instead of “mod-p” Diffie-Hellman. But there’s another possible implementation that you can do with semigroups. The revised key exchange protocol with semigroups looks something like this: Example 2.

Há 3 dias · DiffieHellman(k, B): A function that performs the Diffie-Hellman operation between the private input k and public input B. The output of this function is a unique, fixed-length byte string.¶ It is RECOMMENDED to use Elliptic Curve Diffie-Hellman for this key exchange protocol.
Há 4 dias · In this work, we make significant progress on both questions. We obtain two main results: A 4-party non-interactive key exchange protocol with quadratic security gap, assuming the existence of exponentially secure injective pseudorandom generators, and the subexponential hardness of the computational Diffie-Hellman assumption.
Há 3 dias · Several key figures have made significant contributions to the development of modern cryptography: Whitfield Diffie and Martin Hellman. They are credited with inventing public-key cryptography and the Diffie-Hellman key exchange protocol in 1976. This breakthrough allowed secure communication over insecure channels without the need ...
Há 2 dias · Although RSA is the focus of the batch GCD attacks, due to the inherent necessity of generating unique prime numbers, there exist other cryptosystems that require the creation and usage of large prime numbers as part of the algorithm. Namely, ElGamal (uses 1 prime), Diffie-Hellman (uses 1 prime number), and DSA (which uses 2 prime numbers).
Há 1 dia · A 4-party non-interactive key exchange protocol with quadratic security gap, assuming the existence of exponentially secure injective pseudorandom generators, and the subexponential hardness of the computational Diffie-Hellman assumption. In addition, our scheme is conceptually simpler, and can be generalized to other settings (with more ...
