—Security at low cost is an important factor for cryptographic hardware implementations. Unfortunately, the security of cryptographic implementations is threatened by Side Channel Analysis (SCA). SCA attempts to discover the secret key of a device by exploiting implementation characteristics and bypassing the algorithm's mathematical security. Differential… (More)
We present a three-dimensional reconstructed image of vascular ring in a 2.5-month-old patient, which was obtained using multidetector computed tomography (MDCT). MDCT angiography made an accurate diagnosis of this life-threatening, but correctable, anomaly in an infant with a stridor, repeated respiratory infections and episodes of apnea.
