Experimente zur Entdeckung von P2P Botnetzen

Botnets, which are used to perform various malicious activities, have become a major threat in recent years. Spamming, phishing, stealing sensitive information, conducting distributed denial of service (DDoS) attacks, scanning to find more hosts to compromise using malware are the goals of many botnets, sometimes of low-profile botnets such as the Nugache botnet [1] which used a peer-to-peer (P...

Zeit-Experimente zur Faktorisierung - Ein Beitrag zur Didaktik der Kryptologie

Bei der Übertragung von vertraulichen Nachrichten mit dem RSA-Kryptosystem (siehe z.B. [Witten_Schulz_2006-2010] oder [Schulz_2003]) werden diese durch geeignetes Potenzieren und Rechnung modulo n verschlüsselt; hierbei ist n Teil des öffentlichen Schlüssels und als Produkt von zwei geheimzuhaltenden Primzahlen p und q gewählt. Die Sicherheit der Verschlüsselung steht und fällt dabei mit der Un...

Corpus Luteum function and parturition in cattle and pigs

At term pregnancy in cattle and pigs progesterone is from luteal origin. Like in other domestic animal species, parturition in the cow and pig is preceeded by a sudden drop in the matemal plasma progesterone concentration.

Neue Ansätze zur Lösung des Skalierungs- und Permutationsproblems in konvolutiver blinder Quellentrennung

Corpus luteum function following subtotal hysterectomy in the prepuberal gilt.

The effect of subtotal hysterectomyon maintenance of induced corpora lutea (CL) in prepuberal gilts, 120 to 130 days of age, was studied. Ovulation was induced with 1,000 IU Pregnant Mare Serum Gonadotropin (PMSG) followed 72 hr later with 500 IU Human Chorionic Gonadotropin (HCG). Thirteen gilts (bred controls) were inseminated on Day 0 (Day following HCG=Day 0). Fifty gilts were laparotomized...
