Towards practical key exchange from ordinary isogeny graphs
IACR Cryptology ePrint Archive, 2018We revisit the ordinary isogeny-graph based cryptosystems of Couveignes and Rostovtsev-Stolbunov, long dismissed as impractical. We give algorithmic improvements that accelerate key exchange in this framework, and explore the problem of generating ...

Bi-symmetric Key Exchange: A Novel Cryptographic Key Exchanging Algorithm
2018The most sensitive part of any crypto graphical system is ensuring the security of key exchange. Classical crypto graphical algorithms make use of one-way complex mathematical functions, to encode the key. On the other hand, Quantum crypto graphical systems make use of Q-bits or photons to encode the key.

Unilaterally-Authenticated Key Exchange
2017Key Exchange (KE), which enables two parties (e.g., a client and a server) to securely establish a common private key while communicating over an insecure channel, is one of the most fundamental cryptographic primitives. In this work, we address the setting of unilaterally-authenticated key exchange (UAKE), where an unauthenticated (unkeyed) client ...
