Let's say I have a plaintext, the corresponding ciphertext encrypted using AES-XTS, and the initialization vectors. Is there any way - not brute force, of course - to compute the key?

Even if there's no known way, feel free to share articles on the subject

    There is no known efficient key-recovery attack against AES, no matter the mode of operation. – CodesInChaos Apr 12 '15 at 12:32

    All known ways to obtain the key require more input; like, the power consumption over time of the device that performed the computation. – fgrieu Apr 12 '15 at 12:34
