Cryptographic Key Agreement

Cryptographic Key Agreement

Method of Elliptic Curve Cryptographic Key Agreement Using Coefficient Splitting

This technology efficiently generates cryptographic keys between users that have not previously shared secret keys with each other using an elliptic curve. The design allows encrypted messages to be sent along unencrypted channels and decrypted by the intended recipient upon receipt. This technology does not require extra computing time as well as can be implemented in a non-authenticated key exchange method and in an authenticated key exchange method.
