How does TLS 1.3 work?
TLS 1.3, the latest version of the Transport Layer Security protocol, brings forth significant advancements and improvements over its predecessors. In this discussion, we will delve into some of the key changes introduced by TLS 1.3, namely the increased encryption in the handshake process, deprecation of specific key exchange algorithms, and the introduction of new […]
Understanding TLS and the Handshake
In this one-hour webinar, we will delve into the world of Transport Layer Security (TLS) and focus on one of its fundamental components, the handshake. TLS is a cryptographic protocol widely used to secure communication over computer networks. By analyzing packet traces, we will demystify the TLS handshake process, step by step, and gain a […]
Fundamentals of Cryptography
This webinar is a part of the Cryptography webinar series.
Fundamentals of Cryptography – II
The goal for the second security session is to understand some of the terms which are crucial to cryptography. The explanation will be for those implementing security protocols rather than academics or cryptographers. We will cover: DES 3DES Asymmetric encryption / symmetric encryption Elliptic curve cryptography Certificate authorities Diffie-Hellman key exchange Diffie-Hellman groups Hashed message […]

Connections: IPv6; Loss of Security and Privacy; DNS (Day 1)
Connections is being held April 2-8, 2022, shortly after the IETF 113 meeting. It is a fully online event created jointly by IIESoc & INTC. The first day will include the following keynote presentations: IPv6 -- past, present & future by Bob HindenGoing Dark -- catastrophic security and privacy losses due to loss of visibility by managed private […]
Internationalized Domain Names: Homographic Attacks
ICANN is engaged in an effort for the Internationalization of Domain Names -- that is, making them available in languages other than English. Thıs ınvolves fıgurıng out what new symbols must be used, of course. But also figuring out which of the new symbols are easily confused with each other, or with existing symbols. Just […]
Asynchronous Group Messaging Security
Peer-to-peer group communication has long been a necessity for usability in team coordination. However, the security of such systems has not been well understood or investigated in comparison to one-to-one secure messaging options (such as Signal or even TLS). Based on an ongoing IETF standardization initiative, this presentation will introduce participants to the basic concepts […]
