Cryptographically Generated Addresses (CGAs) were mainly designed to prove address ownership and to prevent the theft of existing IPv6 addresses by binding the owner's public key to the generated address. The address owner uses a corresponding private key to prove its ownership by using signed messages that are originated from that address. Though the CGA approach is quite useful in providing a means...
Cryptographically Generated Addresses (CGA) are employed as an authentication mechanism in IPv6 network to realize the proof of address ownership without relying on any trust authority. The security parameter (Sec) indicates the security level of the CGA address. For Sec value greater than zero, there is no guarantee to stop the brute-force search after certain time. The address generator tries different...
Spam has posed a serious problem for users of email since its infancy. Today, automated strategies are required to deal with the massive amount of spam traffic. IPv4 networks offer a variety of solutions to reduce spam, but IPv6 networks' large address space and use of temporary addresses — both of which are particularly vulnerable to spam attacks — makes dealing with...
Neighbor Discovery Protocol (NDP) is one of the main protocols in IPv6 suite. However, it has no security mechanisms and is vulnerable to various attacks. Using an RSA key pair, cryptographically generated addresses, a digital signature, and X.509 certificates, Secure Neighbor Discovery (SEND) is designed to countermeasure NDP threats. Unfortunately, SEND deployment is still a challenge for several...
Cryptographically Generated Address (CGA) is one of the most novel security features introduced in IPv6 suite. CGA is designed to prevent addresses theft without relying on trust authority or additional security infrastructures. However, CGA is relatively computationally intensive, and bandwidth consuming. Besides, it has some security limitations. This paper defines a Compact and more Secure CGA...
