A phishing email begins the common form of on-line deception, then sends targets to a phishing website where the attacker tries goals to share their credentials. General emails from the phishing targets and the defender are relatively easy to understand. Usually they come from odd addresses, the content is very general and they occur in big quantities. Online deception, however, usually leads to a spear phishing which has significant consequences. Spear-phishing e-mails are sent in a very small volume, target small audiences, sometimes impersonate a trustworthy entity, and redirect targets to a phishing website where an attacker tricks targets to share their identity. Attackers mostly use domain spoof techniques to convince the phishing site even more. The whole process we evaluate. Beginning with phishing mail, we discuss anti-spleen protocols, evaluate the policy and alert of email service...

This paper is based on the key generation and distribution problem in a two-way relay channel, in which there is no direct channel between the key generating terminals. We propose an effective key generation scheme that achieves a substantially larger key rate than that of a direct channel mimic approach. Secure key distribution schemes for group communications allow establishing a secure multi cast communication between a group manager and group members through an insecure broadcast channel. The improved efficiency for key management is realized by periodically refreshing all public private key pairs as well as any multicast keys in all the nodes using only one newly generated function broadcasted by the key generator entity. The article classifies, analyzes and compares the most significant key distribution schemes, by looking at the selective key distribution algorithms, at the pre-distributed secret data management, and at the self-healing mechanisms. It reviews polynomial-based algorithms, exponential arithmetic based algorithms, hash-based techniques, and others. Propose classification of schemes based on the applied cryptographic primitives.
