In this paper we show how the usage of Residue Number Systems (RNS) can easily be turned into a natural defense against many side-channel attacks (SCA). We introduce a Leak Resistant Arithmetic (LRA), and present its capacities to defeat timing, power (SPA, DPA) and electromagnetic (EMA) attacks. keywords: Side Channel Attacks, Residue Number Systems, RNS Montgomery multiplication

Early leak current, i.e. for times similar to the time to peak of the transient current was measured in Myxieola giant axons in the presence of tetrodotoxin. The leak current-voltage relation rectifies, showing more current for strong depolarizing pulses than expected from symmetry around the holding potential. A satisfactory practical approximation for most leak corrections is constant resting...

Monemdjou, Shadi, Leslie P. Kozak, and Mary-Ellen Harper. Mitochondrial proton leak in brown adipose tissue mitochondria of Ucp1-deficient mice is GDP insensitive. Am. J. Physiol. 276 (Endocrinol. Metab. 39): E1073–E1082, 1999.— Mice deficient in mitochondrial uncoupling protein (UCP) 1 are cold sensitive, despite abundant expression of the homologues, Ucp2 and Ucp3 (S. Enerbäck, A. Jacobsson, ...

Introduction: Pancreatic resections are associated with significant morbidity. While most of the complications are well documented in the literature, chyle leak gets scant attention. The aim of this article is to review the etiopathogenesis and management of chyle leak post pancreatic resection. Methods: A medline search of major articles in English literature of 2 or more cases of chyle leak a...

INTRODUCTION I-gel is a relatively new supra-glotitc airway device which is claimed to be superior to laryngeal mask airway. It can be used ingeneral anesthesia with spontaneous ventilation as well as with positive pressure ventilation.This study was designed to assess whether I-gel creates adequate laryngeal seal during positive pressure ventilation in patients undergoing laparoscopic surgery....

Background: Cerebrospinal fluid (CSF) leak is a devastating complication after transsphenoidal surgical approach to pituitary adenoma and sellar repair has been postulated as crucial step in this approach. In this study, we describe our experience regarding sellar repair in pure endoscopic endonasal approach in 240 patients with pituitary adenoma. Methods: During April 2005 to April 2011, a tot...

BACKGROUND Fibrin sealants (FSs) have been used in both open and laparoscopic bariatric surgery to decrease the anastomotic leak rate; however, conclusive evidence to recommend routine use is still lacking. We studied FS use and its effect on the clinical inflammatory response after laparoscopic Roux-en-Y gastric bypass. METHODS Of 474 consecutive patients scheduled to undergo laparoscopic Ro...

BACKGROUND Reports of esophageal anastomotic complications often involve more gastric than colonic reconstructions and are incomplete because of fragmented followup by physicians unfamiliar with the surgical procedure. STUDY DESIGN Three hundred ninety-three consecutive esophagectomy patients had prevalence and risk factors determined for graft ischemia and anastomotic leak; 363 of these pati...

BACKGROUND The aims of the study were to determine the radiological leak rate in those patients who had undergone a resection for left-sided colorectal cancer and to see if the presence of a leak can be related with the postoperative clinical period. We also aimed to identify any common factors between patients with leak. METHODS A retrospective analysis of prospectively collected data of all...

OBJECTIVES To determine the risk factors in diabetic patients that are associated with increased postcolectomy mortality and anastomotic leak. DESIGN A prospectively acquired statewide database of patients who underwent colectomy was reviewed. Primary risk factors were diabetes mellitus, hyperglycemia (glucose level ≥ 140 mg/dL), steroid use, and emergency surgery. Categorical analysis, univa...
