Intentional Flaw in GPRS Encryption Algorithm GEA-1

Posted on by

General Packet Radio Service (GPRS) is a mobile data standard that was widely used in the early 2000s. The first encryption algorithm for that standard was GEA-1, a stream cipher built on three linear-feedback shift registers and a non-linear combining function. Although the algorithm has a 64-bit key, the effective key length is only 40 bits, due to “an exceptional interaction of the deployed LFSRs and the key initialization, which is highly unlikely to occur by chance.”

GEA-1 was designed by the European Telecommunications Standards Institute in 1998. ETSI was — and maybe still is — under the auspices of …

Researchers have developed models that could predict mild cognitive impairment and dementia with 88 percent accuracy

A fascinating new study from a team of US researchers has used machine learning techniques to develop algorithms that can analyze naturalistic driving data and detect mild cognitive impairment and dementia in a driver. The work is still in the preliminary stages, however, the researchers claim it could be possible in the future to detect early signs of dementia using either a smartphone app or devices incorporated into car software systems.

Brexit Deal Mandates Old Insecure Crypto Algorithms

Posted on by

In what is surely an unthinking cut-and-paste issue, page 921 of the Brexit deal mandates the use of SHA-1 and 1024-bit RSA:

The open standard s/MIME as extension to de facto e-mail standard SMTP will be deployed to encrypt messages containing DNA profile information. The protocol s/MIME (V3) allows signed receipts, security labels, and secure mailing lists… The underlying certificate used by s/MIME mechanism has to be in compliance with X.509 standard…. The processing rules for s/MIME encryption operations… are as follows:

  1. the sequence of the operations is: first encryption and then signing,
    …

Taking a Crack at the Traveling Salesman Problem

Posted on by

The human mind is a path-planning wizard. Think back to pre-lockdown days when we all ran multiple errands back to back across town. There was always a mental dance in the back of your head to make sense of how you planned the day. It might go something like “first …read more

Potential for “selfies” to detect heart disease raises ethical concerns

Posted on by

A new algorithm has been developed to detect coronary artery disease solely from patient facial photos. The proof-of-concept, published in the European Heart Journal, needs more refinement before it becomes a useful clinical tool but independent expert… Continue reading Potential for “selfies” to detect heart disease raises ethical concerns→

MIT’s search and rescue algorithm could quickly find those lost at sea

Posted on by

The MIT team set out to develop an improved method for tracking lost objects at sea by focusing on what it refers to as hidden “traps

The ocean can be a ferociously wild place, which makes locating lost people and objects a tall order for first responders. Researchers at MIT have developed a new algorithm that takes stock of ocean conditions to determine in real-time where these missing items and people are likely to appear, which could give the efficiency of search and rescue operations a big boost.
