Seminar Connected and Mobile Systems: Internet Protocols (Master)

In this seminar topic, the current state of TLS 1.3, the successor of SSL, TLS 1.0, 1.1, and 1.2, should be presented. Not only the current state of the Internet Draft proposed by the TLS working group is of interest, also the papers related to TLS 1.3 published by the research community should be described.

• Current draft of TLS 1.3
• A cryptographic analysis of the TLS 1.3 handshake protocol candidates
• Augmented secure channels and the goal of the TLS 1.3 record layer

• On the impact of congestion control for Concurrent Multipath Transfer on the transport layer
• RFC6356: Coupled Congestion Control for Multipath Transport Protocols
• Load Sharing for the Stream Control Transmission Protocol (SCTP)

• The Opportunistic Linked Increase Algorithm
• Delay-based Congestion Control for MPTCP
• The Balanced Linked Increase Algorithm

When people are ask about the advantages of IPv6 against IPv4 they answer: more/longer/ugly addresses. But isn't there more?

Find the advantages that are most interesting for you and describe them in detail. The following list is far from complete:

• IPv6 Multihoming without Network Address Translation
• Security Architecture for the Internet Protocol
• Mobility Support in IPv6

The intention of uIP was to allow even small and tiny devices to use the host-to-host interoperability of the TCP/IP Stack. To make uIP ready for the upcoming IoT, there is also an extension for uIPv6 with much higher adress space.

• Full TCP/IP for 8-bit architectures
• Making sensor networks IPv6 ready

Bitcoin is a decentralized currency that can be used to pay a lot of different goods and services. The system works in a peer-to-peer manner and all participants maintain Bitcoin together. The peer-to-peer communication works via the Bitcoin protocol. The task is to give an overview about the Bitcoin protocol and to describe how it works internally. Recently, changes to the Bitcoin protocol were proposed but their implementation was complicated due to the peer-to-peer system. The task is further to describe why changes are complicated and what might happen if bugs appear in the protocol. Will the currency's value crash in that case?

4G (LTE) has been available for some years now and is widely used. Recently, a very hot topic in research and standardization communities is it's successor - 5G. It is estimated to go live by 2020. But what will it be capable off? Like all the former advancements to the respective newer versions, an important point is the maximum connection speed. But there is much more. What are other important novelties in your opinion? Describe the use cases and how these ideas are planned to be implemented technically.

• What Will 5G Be?
