There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.

Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

Resolving the molecular details of proteome variation in the different tissues and organs of the human body will greatly increase our knowledge of human biology and disease. Here, we present a map of the human tissue proteome based on an integrated omics approach that involves quantitative transcriptomics at the tissue and organ level, combined with tissue microarray-based immunohistochemistry, to achieve spatial localization of proteins down to the single-cell level. Our tissue-based analysis detected more than 90% of the putative protein-coding genes. We used this approach to explore the human secretome, the membrane proteome, the druggable proteome, the cancer proteome, and the metabolic functions in 32 different tissues and organs. All the data are integrated in an interactive Web-based database that allows exploration of individual proteins, as well as navigation of global expression patterns, in all major tissues and organs in the human body.

Cryptosystem designers frequently assume that secrets will be manipulated in closed, reliable computing environments. Unfortunately, actual computers and microchips leak information about the operations they process. This paper examines specific methods for analyzing power consumption measurements to find secret keys from tamper resistant devices. We also discuss approaches for building cryptosystems that can operate securely in existing hardware that leaks information.

Differential Power Analysis

This chapter examines an application that can potentially benefit from trusted computing, namely single sign-on (SSO). SSO gives the user the ability to log into systems and applications without the need to maintain separate authentication credentials for each such system and application. In other words, an SSO scheme allows the user to log into (ideally) all relevant systems and applications, using only one set of authentication credentials (e.g. only one username/password pair). In the remainder of the chapter, we use the generic term 'service provider' (SP) to refer to systems and/or applications in the context of SSO.

What does trust mean? For the purposes of this book, perhaps the simplest definition would be that trusted computing refers to a computer system for which an entity has some level of assurance that (part or all of) the computer system is behaving as expected. The entity may be any one of various things, including the human user of the PC or a program running on a remote machine. The degree of coverage of this assurance, that is, whether it covers all aspects of the system or just some part, and the nature of the entity to which assurance is provided, vary depending on the system and the environment within which it is used.

What is trusted computing

Future mobile systems are expected to exploit the flexibility of agent-based software in a variety of ways. This includes agents providing both middleware and application-level functionality. Realising the full benefits of this innovative approach requires that security issues are properly addressed. There are many security issues associated with agent-based systems; some of the most difficult to deal with arise when agents themselves can be mobile. There has been much recent interest in developing cryptographic protocols designed especially for securing mobile agents. However, this work has mainly been ad hoc in nature, i.e., it has not been developed in response to a thorough analysis of the security requirements for a particular agent application. The paper describes research intended to help rectify this gap by providing a detailed security architecture, including a security model and a specification of security services provided within the model.

Perfect binary arrays and difference sets

In a mobile ubiquitous environment, service interactions between a user device and a service provider should be secure, regardless of the type of device used to access or consume a service. We present a secure device management framework (SDMF), designed to securely deliver services to user devices, whilst also hiding (some of) the complexity of security management from users. Key to this framework is the device management entity (DME), that manages a user device's security credentials, and interacts with service providers on its behalf. This framework also provides users with assurance that a compromised device cannot consume the delivered service, and, at the same time, prevents users from illegally sharing their credentials with other users. We achieve these objectives using trusted computing functionality and certain other security mechanisms.
