SB 25: Privacy Enhancement Flashcards
What is a re-mailer?
An anonymous remailer is a server that receives messages with embedded instructions on where to send them next, and that forwards them without revealing where they originally came from. There are cypherpunk anonymous remailers, mixmaster anonymous remailers, and nym servers, among others, which differ in how they work, in the policies they adopt, and in the type of attack on the anonymity of e-mail they can (or are intended to) resist.
What is onion routing?
A method for routing that ensures each node in the route knows only the two adjacent nodes in the route.
Onion routing is a technique for anonymous communication over a computer network. In an onion network, messages are encapsulated in layers of encryption, analogous to the layers of an onion. The encrypted data is transmitted through a series of network nodes called “onion routers,” each of which “peels” away a single layer, revealing the data’s next destination. When the final layer is decrypted, the message arrives at its destination. The sender remains anonymous because each intermediary knows only the location of the immediately preceding and following nodes.
What is an anonymizer?
Hides the origins of the connection. Functions like a proxy server. Primarily works for emails and HTTP.
What is a cookie?
It stores information about the users activity on the website. Puts the storage requirement on the client side instead of the server.
