signature s hemes based on the Gap-DiÆe-Hellman-group signature s heme Alexandra Boldyreva August 12, 2002 Abstra t We propose a robust proa tive threshold signature s heme, a multisignature s heme and a blind signature s heme whi h work in any Gap DiÆe-Hellman (GDH) group (where the Computational DiÆe-Hellman problem is hard but the De isional DiÆe-Hellman problem is easy). Our onstru tions ar...

Septicemic Escherichia coli 4787 (O115: K-: H51: F165) of porcine origin possess gene clusters related to extraintestinal E. coli fimbrial adhesins. This strain produces two fimbriae: F165(1) and F165(2). F165(1) (Prs-like) belongs to the P fimbrial family, encoded by foo operon and F165(2) is a F1C-like encoded by fot operon. Data from this study suggest that these two operons are part of two ...
