End-to-end encryption (E2EE) is the encryption of transmitted data across all transmission stations. Only the communication partners (the respective endpoints of the communication) can decrypt the message. When using symmetric encryption, the key to ensure end-to-end encryption must only be known to the end communication partners. When using asymmetric encryption, it must be ensured that the … [Read more...]

Technical Countermeasures of Browser Fingerprinting (Tracking Technique)
In our earlier article, we have explained that fingerprinting is a user tracking technique. It is used to uniquely identify and track end devices and thus users. The method does not require physical access to the device. In particular, the data generated by web browsers is used for fingerprinting, this is known as browser fingerprinting. The aim of the countermeasures is to increase privacy … [Read more...]
What Are DNS Spoofing and Cache Poisoning
DNS spoofing and cache poisoning are IT security attacks on the Domain Name System to forge the mapping between a domain name and its IP address. The purpose is to steer traffic to another computer unnoticed, for example, to carry out a phishing or pharming attack. If traffic is directed to an unreachable destination, it can be used to carry out a denial-of-service attack. The terms DNS … [Read more...]

HTTP/3: Comparison With HTTP/1.1 and HTTP/2
HTTP up to version 2 relies on the Transmission Control Protocol (TCP) as the transport protocol. TCP acknowledges receipt of each data packet. As a result, in the event of packet loss, all other packets have to wait for the lost one to be retransmitted (head-of-line blocking). Google has been working on an alternative since 2012 under the name QUIC, which was adopted by the IETF and … [Read more...]
