Secrecy News (Nov 26) - "Autonomy in Weapon Systems":
http://www.fas.org/blog/secrecy/2012/11/weapons_autonomy.html

One note.  Mention is made in this document about the importance of  
"verification and validation" (V&V) of systems.  Earlier this month,  
DARPA's High-Assurance Cyber Military Systems (HACMS) program awarded a  
4.5 year $18M contract to an international consortium "to develop a  
complete, formally proven architecture to protect the control and  
communication systems of an aerial vehicle from compromise by faults and  
targeted attacks."

Part of that award went to National ICT Australia [ @NICTA ] which toots  
its own horn for formally verifying 7,500 lines of C code. That tells you 
something about the challenge of "formal verification" which  
mathematically proves a system will behave as specified - a much higher  
bar than "rigorous" testing.
http://en.wikipedia.org/wiki/Formal_verification

That also tells you something about the complexity of systems which have  
thus far achieved formal verification.  For comparison, the Linux  
kernel---which sits at the heart of many of the workstations used by the  
US military's remote pilots---surpassed 15 million lines of code in  
January, leading the creator of Linux, Linus Torvalds, to lament that he  
is "afraid of the day" when there will be an error that "cannot be  
evaluated anymore."
http://www.tomshardware.com/news/Linux-Linus-Torvalds-kernel-too-complex-code,14495.html

Considering DARPA knows the path to formal verification of larger systems 
must be cleared - demand it.  The challenge of formal verification presents 
a strong argument for delaying deployment of lethal autonomous systems.
