Abstract :
SECURITY TECHNOLOGY is back on the agenda in the wake of the terrorist attack on the Charlie Hebdo magazine. The public worries about security on the one hand, personal liberties and privacy on the other. The Prime Minister warned against encryption technology that allows truly secret communications and promised legislation, which could mean reviving the bill that protestors dubbed the ´snooper´s charter´ and would make ISPs store all communications and the means to read them. Limiting encryption may be unworkable. Or, in time, opinion may swing back towards the civil liberties side. We shall see.
