Speculation started on Bond fansites after a Foreign Office worker in the Helmand province signed up to work as a consultant for the spy franchise.
The individual has reportedly signed a confidentiality agreement to prevent them discussing the follow-up to 2008's Quantum Of Solace.
Bond previously visited Afghanistan in Timothy Dalton's 1987 outing The Living Daylights, in which the secret agent was imprisoned in a Russian camp in the country.
Eon Productions has refused to comment on the rumours.
The 23rd Bond movie is expected to be released at some point in 2011. It will be Daniel Craig's third outing as the spy.
