TcTssValidation validation = TcTssStructFactory.newValidation();
validation.setExternalData(...nonce...);

TcIPcrComposite pcrSelection = context.createPcrCompositeObject(0);
pcrSelection.selectPcrIndex(...yourfavouritePCR...);

TcTssValidation quoteResult = context.getTpm().quote(aikKey, pcrSelection, validation);

... = quoteResult.getData();            // plain data
... = quoteResult.getValidationData();  // signature
