The goalkeeper was a crucial member of the Serie A-winning Juve team under Antonio Conte and helped Italy reach the final of Euro 2012, though Spain beat them comfortably.
The 34-year-old wrote on his official Facebook page: "2012 gave me a lot of joy.
"Juventus bounced back to win the Scudetto, I had a beautiful European adventure with the national team, I lifted my first trophy as captain and then [Juve had] a really superb beginning to this season.
"This group aims higher in every competition. In 2013 I hope to convey all my determination and confidence so that the team keep being able to fight on every front."
The Bianconeri currently sit top of Serie A on 44 points after 18 matches, seven points clear of second-placed Lazio.
In Europe, Conte's team have been drawn against Celtic in the last 16 after knocking Champions League title holders Chelsea out at the group stage.
