hPIN/hTAN: A lightweight and low-cost e-banking solution against untrusted computers
In this paper, we propose hPIN/hTAN, a low-cost hardware token based PIN/TAN system for protecting e-banking systems against the strong threat model where the adversary has full control over the user's computer. This threat model covers various kinds of attacks related to untrusted terminal computers, such as keyloggers, screen scrapers, session hijackers, Trojan horses and transaction generators. The core of hPIN/hTAN is a secure and easy user-computer-token interface. The security is guaranteed by the user-computer-token interface and two underlying security protocols for user/server/transaction authentication. The hPIN/hTAN system is designed as an open framework so that the underlying authentication protocols can be easily reconfigured. To minimize the costs and maximize usability, we chose two security protocols dependent on simple cryptography (a cryptographic hash function). In contrast to other hardware-based solutions, hPIN/hTAN depends on neither a second trus ted channel nor a secure keypad nor external trusted center. Our prototype implementation does not involve cryptography beyond a cryptographic hash function. The minimalistic design can also help increase security because more complicated systems tend to have more security holes. As an important feature, hPIN/hTAN exploits human users' active involvement in the whole process to compensate security weaknesses caused by careless human behavior

The aim of the present study was to evaluate the changes in the survival of patients diagnosed with mPCa prior to and in the early period of the implementation of these new agents.The study population consisted of 207 men diagnosed in 1997 and 316 men diagnosed in the period 2007-2013 with de novo mPCa and managed with initial endocrine therapy. Men were followed for overall survival and PCa-specific survival.At the time of diagnosis, men diagnosed in the period 2007-2013 had less co-morbidity, lower prostrate-specific antigen levels and lower clinical tumour categories than men diagnosed in 1997. A significantly higher proportion of men diagnosed in 1997 were managed with surgical castration (57% versus 9%). Only one patient diagnosed in 1997 received second-line therapy compared with 81 men (26%) diagnosed in the period 2007-2013. The median overall survival was significantly longer for men diagnosed between 2007 and 2013 compared with men diagnosed in 1997 (39.4 months versus 24.2 months, p < 0.0001). Likewise, the cumulative incidence of PCa-specific death was higher among men diagnosed in 1997 compared with men diagnosed between 2007 and 2013, with 5-year cumulative incidences of 72% and 47%, respectively (p < 0.0001).Survival in men diagnosed with metastatic PCa has improved significantly over time. The improved survival can in part be explained by lead-time bias, but also by the introduction of new life-prolonging treatments.Aase and Ejnar Danielsens Foundatio
