I studied information technology at Oslo College of Engineering back in
1985 – 1988.
Then I supplemented this with a Computing Science degree from
This degree was then recognized by NTH,
I have worked in the industry for many years, including for Ericsson Norway,
System Sikkerhet AS, Telenor
Kompetanse and Telenor
R&D.
At Ericsson (1991 – 1993) I worked as a system tester. What we
tested was system software for ISDN and NMT
exchanges.
At System Sikkerhet AS (1993 – 1995) I
worked mainly with evaluation of UNIX based military software for an email
exchange server.
This was classical UNIX System V software and classical Orange Book
evaluation (well, we did have an extended set of criteria…).
Then I moved on to Telenor Kompetanse
(1995 – 1998), which was a Telenor internal
unit for system courses.
My primary task was to teach system signaling and system architecture.
This even included a little bit of NMT 450/900, but
the main focus was on the GSM system.
In 1998 Telenor establish a local branch office
of Telenor R&D in Grimstad,
and I was there from day one. My work now shifted from teaching GSM to technical evaluation of GPRS.
From 1999 my primary focus was on UMTS and
access security, and I was the Telenor delegate to
the (3GPP) SA3 work group (security) from 1999 to 2009.
During the last few years the main focus was of course not with UMTS anymore, but rather with the emerging LTE system (which is the 4G initiative from 3GPP*).
In 2002 I started my PhD studies while working for Telenor
R&D.
Formally, my PhD studies were conducted at Aalborg University (AAU),
The reason for this was that UiA, at the time,
wasn’t a university. But UiA did have an
agreement with AAU, and so I had one supervisor at AAU (prof.
Ramjee Prasad) and one at UiA
(prof. Vladimir Oleshchuk).
Nice arrangement for me. Anyway, I finished my PhD in April 2008 in
Now, by the time I had completed my PhD the local Telenor
R&D branch office had closed down.
I didn’t want to be relocated to
The agreement included me quitting my job voluntarily and Telenor R&D hiring me back as a (self employed)
consultant.
So from mid 2008 and until end of 2009 I have been working for Telenor R&D as a contract consultant, but this
arrangement wasn’t meant to last forever.
Therefore I applied for a Postdoc position at UiA and from Decemeber 2009 I
have been working for UiA.
(apart from doing my PhD studies here at UiA and have also had an office and a 20% assoc. prof. position here at UiA since
2008 so I’m not at all new to this place)
Now I am a postdoctor at

* LTE
isn’t formally a 4G system; it’s more like
a 3.9G system. It will become a 4G system with LTE-Advanced.
However, the security architecture isn’t really
affected by this and so plain vanilla LTE already has
the “4G” security architecture in place.
