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 either key exchange or for ciphering, assume that the curve E, the field Fsubq/sub...
Recently, three key exchange protocols were proposed that integrated the Diffie-Hellman key exchange into the digital signature algorithm (DSA). It was cla... Phan,R C.-W. - 《IEEE Communications Letters》 被引量: 0发表: 2005年 Enhancement of Security of Diffie-Hellman Key Exchange Protocol ...

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...
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...

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 ...
For 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 protocol to provide the computation and communication ef...
These last two schemes are the first provably-secure one-round protocols for authenticated 2-party key exchange which provide forward secrecy... IR Jeong,J Katz,HL Dong - Applied Cryptography & Network Security, Second International Conference, Acns, Yellow Mountain, China, June 被引量: 232发表...
On the other hand, through this work, we also highlight that the existence of insider attacks needs to be taken into consideration in the three-party setting. 展开 关键词: elliptic curve cryptography unknown key-share attack three-party authenticated key exchange ...
