This paper describes the addition law for a new form for elliptic curves over fields of characteristic 2. Specifically, it presents explicit formulae for adding two different points and for doubling points. The case of differential point addition (that is, point addition with a known difference) is also addressed. Finally, this paper presents unified point(More)
Anti-Gal is a natural Ab abundantly produced in humans. It interacts specifically with the carbohydrate epitope Gal alpha 1-3Gal beta 1-4GlcNAc-R (termed the alpha-galactosyl epitope). This epitope is expressed in large amounts on thyrocytes of nonprimate mammals, but not of humans. We have previously found that binding of anti-Gal to alpha-galactosyl(More)
A proxy re-encryption (PRE) scheme allows a designated proxy, that has beforehand received a so-called re-encryption key, to translate a ciphertext intended to one user to a ciphertext intended to another one. Traditionally, the re-encryption key is generated at the initiative of the initial receiver and ideally, no secret keys should be known to the proxy.(More)
