Comparison of the Diagnostic Utility of 4D-DSA with Conventional 2D- and 3D-DSA in the Diagnosis of Cerebrovascular Abnormalities.
BACKGROUND AND PURPOSE 4D-DSA is a time-resolved technique that allows viewing of a contrast bolus at any time and from any desired viewing angle. Our hypothesis was that the information content in a 4D-DSA reconstruction was essentially equivalent to that in a combination of 2D acquisitions and a 3D-DSA reconstruction. MATERIALS AND METHODS Twenty-six consecutive patients who had both 2D- an...
متن کاملElliptic Curve DSA (ECDSA): An Enhanced DSA
The Elliptic Curve Digital Signature Algorithm (ECDSA) is the elliptic curve analogue of the Digital Signature Algorithm (DSA), and is under consideration for standardization by the ANSI X9 committee. Unlike the normal discrete logarithm problem and the integer factorization problem, the elliptic curve discrete logarithm problem has no subexponentialtime algorithm. For this reason, the strength...
متن کاملOn the Big Gap Between |p| and |q| in DSA
We introduce a message attack against DSA and show that the security of DSA is indeed reduced to the following problem, i.e., find θ ∈ Z∗q such that z = (ĝθ mod p)mod q where Ordp(ĝ) = q and z ∈ Z∗q is randomly chosen by the adversary. Compared with the common key-only attack, i.e., find x ∈ Z∗q such that y = gx mod p the message attack is more effective because of the big gap between |p| (1024...
