Two sh is a new block cipher with a 128 bit block, and a key length of 128, 192, or 256 bits, which has been submitted as an AES candidate. In this paper, we brie y review the structure of Two sh, and then discuss the key schedule of Two sh, and its resistance to attack. We close with some open questions on the security of Two sh's key schedule.

BACKGROUND Determination of drug safety and tolerability is usually based on the frequency of certain key adverse events (AEs) rather than the frequency of all-grade toxicities. We assessed the reporting of key AEs in oncology randomized, controlled trials (RCTs) and compared that with the expectations of the European Organization for Research and Treatment of Cancer (EORTC) membership. MATER...

There are various methods to collect adverse events (AEs) in clinical trials. The methods how AEs are collected in vaccine trials is of special interest: solicited reporting can lead to over-reporting events that have little or no biological relationship to the vaccine. We assessed the rate of AEs listed in the package insert for the virosomal hepatitis A vaccine Epaxal(®), comparing data colle...

In this paper an efficient hardware architecture design and implementation of all candidates of AES encryption standards AES-128, AES-192 and AES-256 on the same hardware is proposed. AES algorithm proposed by NIST has been widely accepted as best cryptosystem for wireless communication security. The hardware implementation is useful in wireless security like military and mobile phones. This co...

OBJECTIVES Acetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDs) are antipyretic analgesics with established adverse effects (AEs); however, only a few studies have compared their AEs simultaneously. We aimed to compare the AEs of these medications to confirm the respective frequencies of both rare and major AEs. METHODS We used a high-quality database for spontaneous adverse drug e...
