This makes the elliptic curve cryptography to gain wide acceptance as an alternative to conventional cryptosystems (DSA, RSA, AES, etc.). All existing protocols for elliptic curve cryptosystems that are used for
In cryptography, key exchange refers to the process through which encryption keys are exchanged between two or more parties. The key enables each party to encrypt messages they wish to send and decrypt messages they have received. Encryption provides a layer of security between your data and poten...
1 Introduction to Key Exchange What Are Key Exchange Protocols? One of the main goals of cryptography is to provide secure communication channels between different parties. Security here means various flavors of data secrecy, message integrity, and communicant authenticity. One way to construct secure...
Elliptic curve cryptographyMobile-commerce environmentsFor secure communications in public network environments, various three-party authenticated key exchange (3PAKE) protocols are proposed to provide the transaction confidentiality and efficiency. In 2008, Chen et al. proposed a round-efficient 3PAKE ...
That's because these two protocols allowed clients and servers, as well as servers and servers, to exchange cryptographic keys over an insecure medium (the Internet) and, in turn, enable them to transact electronically securely. Elliptic curve cryptography has recently introduced new exchange protocol...
become widely used for encryption, key exchange continues to be a challenging part of securing data exchanges over the internet. Data traversing the internet is exposed to a variety of intermediary systems, so it became necessary to implement encryption protocols for the secure exchange of private ...
We develop a compositional method for proving cryptograph- ically sound security properties of key exchange protocols, based on a symbolic logic that is interpreted over conventional runs of a protocol against a probabilistic polynomial-time attacker. Since reasoning about an unbounded number of runs ...
