Abstract:
<p>Communication is and has always been important for the human as we aredesigned by evolution to communicate as a way to survive and reproduce. Whatmany people do not think about is that music and communication are very closelyrelated due to the fact that music is a type of communication. In this thesis wehave focused on the field of music and communication to discuss the possibilityof combining these to areas to provide better information technology services.More specifically we have focused on discussing the advantages of combining thecommunication technology of instant messaging with music

Facebook Messenger, ChatSecure, Line, QQ and WhatsApp represent examples of Mobile Messaging Applications (MMAs) that collectively facilitate instant and global communications, in which billions of audio, image, text and video messages are exchanged on a daily basis.

Abstract:
The SMS gateway EMG uses separate threads for each connection. This requires a large number of locks to avoid data corruption, and causes problems when scaling to thousands of connections. The CPU load goes very high, and the amount of addressable memory per thread becomes low. This report examines an alternative implementation, where each thread instead handles a separate part of the processing. The two architectures are compared based on throughput, resource utilisation, code complexity and more. The results show what while throughput is about the same, the alternative implementation is bett

Abstract:
What formal guarantees should a secure messaging application provide? Do the most widely-used protocols provide them? Can we do better? In this thesis we answer these questions and with them give a formal study of modern secure messaging protocols, which encrypt the personal messages of billions of users. We give definitions and analyses of two protocols: one existing (Signal) and one new (ART). For Signal, we begin by extending and generalising classic computational models, in order to apply them to its complex ratcheting key derivations. With a threat model in mind we also define a security

In today’s society, people are more aware of the need for encryption to keep their private information safe. Therefore chat apps like WhatsApp and Signal are popular since they allow people to talk encrypted over instant messaging. However, normal encryption might not always be enough to keep the data safe. An adversary who can record and keep a transcript of everything a person sends over the Internet, could force the person to reveal the key used for encryption and therefore know what they sent.
