Hi, try "encryting" the cipher text again. The CC2420 AES works in CTR mode, meaning encryption and decryption are the same operation.
Moreover, if you send your packets anyway, you can use the built-in functionality of the CC2420 chip to encrypt all outgoing packets on the fly. It will also decrypt incoming packets automatically. TinyOS already allows for this, simply Google for "tinyos cc2420 security tutorial". Note that the actual wiki seems to be down, but you use the Google cache. That worked for me.
