,Topic 1 - Introduction

Lecture 1

Tor = hides your identity (IP address) on the web

Obtaining relays
1 Publicly available list (default) (blocked)
- Download and choose randomly
- Easy to block

2 Private relays (bridges) (not all blocked)
- Set of relays not included in public list
- Changed frequently
- Can be requested (for example, by email)
- Only give out small number, not complete list

Protocols
- Algorithm for communication between two or more parties
- Defines the rules of communication
- Provides a service (function signature)

,Layers
There are layers in protocols that provide levels of abstraction, because every layer provides
a service that is only communicated to the layer above or below




Network layers are often the same layers on multiple machines, and only the lowest one
actually communicates

, Physical layer
Sends one bit via a physical medium like an ethernet cable

Data link layer
Sends a sequence of bits over a link reliably, like a phone sending data to a wifi router. Here,
reliability is needed, so there needs to be something in place to ensure that the data is sent
correctly

Network layer
Sends data from one computer in a network to another




Transport layer
Sends data in a reliable or unreliable way over an unreliable network

Application layer
Sends application-specific information over the network
