There is more than the UI at stake here, i.e. the basic functionality of
the scheme. Say you distribute shares in a 4 out of 7 scheme (ABCDEF)
and share A is published on the web. How do you recover from the
remaining 3 out of 6 scheme into a 4 out of 6 scheme without having a
key
So with about 1 000 000 USD and a full year you would get 122 bits
already now and agencies have a bit more budget than this! Furthermore,
the algorithm parallelizes extremely well and can handle a batch of 100
targets at only 10 times the cost.
No it cannot handle a bunch of a hundred
We are pleased to announce that we have set a new record for the elliptic
curve discrete logarithm problem (ECDLP) by solving it over a 112-bit
finite field. The previous record was for a 109-bit prime field and
dates back from October 2002.
First of all congratulations to the team at EPFL!
Examples of side channel analysis on real systems I however have never
seen in the field. Any rumors would be highly appreciated.
At Crypto'08 a team from Bochum demonstrated their side-channel attack on
KeeLoq. There were some theoretical attacks before but the SCA really
broke it.
