Important notice about SecAppDev 2020

Due to the current situation with COVID-19 (Corona), with deep regret, we feel bound to postpone SecAppDev 2020 indefinitely. While there have been no official instructions to postpone events such as ours or reduce travel, both attendees and speakers have informed us that they are unable to attend SecAppDev.

We hope everyone in SecAppDev stays healthy, and wish everyone the best for the coming months.

The never-ending crypto wars

Bart Preneel
Monday March 9, 14:00 - 15:30
Short description

Law enforcement agencies complain that encryption impedes their work, hence they keep asking for bans, backdoors or access to keys. Many others argue that weakening encryption would undermine legitimate security interests of citizens and society. Is there a right decision and will this debate ever end?

Abstract

The 1993 Clipper Chip has sparked the debate on law enforcement access to encrypted communications. As the proposal was withdrawn, civil society believed that they won the first crypto war. However, law enforcement and intelligence services have since developed many techniques to bypass cryptographic solutions. In spite of this, the crypto wars have returned. The debate is now much more complex as it moves from encrypted communications to meta data, data stored in the cloud, data stored on confiscated devices, and malware to get real-time access to devices. Several countries have enacted laws to compel system providers to develop backdoors in encryption.

This session will analyze the state of affairs and explore future options.

Key takeaway

The crypto war is ongoing, but the focus on encryption may well be a diversion tactic.
