Attacks Against the WAP WTLS Protocol

1999

The WAP WTLS protocol was designed to provide privacy, data integrity, and authentication for wireless terminals. The protocol is currently being fielded, and it is expected that the protocol will be contained in millions of devices in a few years.

A Note on Keys and Keystreams of Chacha20 for Multi-key Channels

2018

In this paper we analyze the keystreams generated by the Chacha20 stream cipher. We also compare these to the ones generated by its predecessor, the RC4 stream cipher. Due to the proposed multi-key channels in the upcoming TLS 1.3 standard we analyze the behavior of the keystream in the boundary case where there is a single bit difference between two keys used for the initiation of the stream cipher algorithms. The goal is to check whether a single bit change in the key has any predictable influence on the bits of the keystream output.
