Abstract: Embodiments may be generally directed to techniques to encrypt and decrypt data in a first fuse block array using an encryption key of a second fuse block array, the second fuse block array having the encryption key comprising a plurality of segments of bits, an inverse encryption key comprising a second plurality of segments of bits, each segment of the inverse encryption key to correspond with a particular segment of the encryption key, and a random pattern having equally distributed bit values, the random pattern to enable detection of voltage attacks on the second fuse block array.
