Secure communications between mobile subscribers and their associated operator networks require mutual authentication and key derivation protocols. The 3GPP standard provides the AKA protocol for just this purpose. Its structure is generic, to be instantiated with a set of seven cryptographic algorithms. The currently-used proposal instantiates these by means of a set of AES-based algorithms ca...

Background: Through knee amputation (TKA) may offer benefits over above (AKA) in patients unsuitable for below amputation. This retrospective analysis compared surgical and rehabilitation outcomes post TKA AKA. Methods: All AKA procedures recorded the Scottish Physiotherapy Amputee Research Group dataset from January 2007 to December 2017 were included analysis. aetiologies, re-amputations bila...

After analyzing the long-term evolution (LTE) authentication and key agreement process (EPS-AKA), its existing security vulnerabilities are pointed out. Based on elliptic curve cryptography (ECC) self-certified public keys, this paper proposes an ECC scheme (ESC-AKA). This includes addition of a trusted center (TC), which generates keys for home subscriber server (HSS), mobility management enti...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014204204 DESCRIPTION Introduction Congenital rubella syndrome (CRS) is a spectrum of clinical findings in a patient that results from primary maternal infection with rubella virus. Diagnosis is usually made clinically but imaging findings can prompt the diagno...

Post-mortem biochemistry, including the analysis of beta-hydroxybutyrate (BHB), is increasingly employed in forensic medicine, especially conditions such as diabetes and chronic alcoholism. However, not much known about associations between age, body mass index (BMI), sex BHB concentrations ketoacidotic conditions. To retrospectively study association BMI several conditions, diabetic ketoacidos...
