“…We then use the remote DMA to inject the fault (Figure 3-III). For this purpose we extended the Inception framework [37] to be able to read and write memory via a FireWire cable (limitations to this approach and countermeasures are discussed in Section 9.3) 5 . After the fault has been injected, we resume the execution of GnuPG.…”

Adversaries with physical access to a target platform can perform cold boot or DMA attacks to extract sensitive data from the RAM. In response, several main-memory encryption schemes have been proposed to prevent such attacks. Also hardware vendors have acknowledged the threat and already announced respective hardware extensions. Intel's SGX and AMD's SME will provide means to encrypt parts of the RAM to protect security-relevant assets that reside there.Encrypting the RAM will protect the user's content against passive eavesdropping. However, the level of protection it provides in scenarios that involve an adversary who is not only able to read from RAM but can also change content in RAM is less clear. Obviously, encryption offers some protection against such an "active" adversary: from the ciphertext the adversary cannot see what value is changed in the plaintext, nor predict the system behaviour based on the changes. But is this enough to prevent an active adversary from performing malicious tasks?This paper addresses the open research question whether encryption alone is a dependable protection mechanism in practice when considering an active adversary. To this end, we first build a software based memory encryption solution on a desktop system which mimics AMD's SME. Subsequently, we demonstrate a proof-of-concept fault attack on this system, by which we are able to extract the private RSA key of a GnuPG user. Our work suggests that transparent memory encryption is not enough to prevent active attacks.

The steady improvement in the quantity of information which can be delivered to a remote computer terminal and in the sophistication with which it can be manipulated, together with the continued drop in cost of information technology, may have dramatic effects on the way business is conducted in the travel and tourism industries (including hospitality). Today, direct purchase of travel by electronic means is a practical possibility. The research reported here explores the prospects for direct retailing by electronic means, and the implications for the industry of this. It includes the results of a survey of senior people in the UK travel and tourism industry and its suppliers, carried out in 1995. The paper concludes that the most rapid changes will be in the business travel market, followed by the market for single components of travel (e.g. an airfare or a hotel booking). Changes in other markets will be slower. These changes represent both threats and opportunities for the industry. The number of high‐street travel agents can be expected to fall, but there will remain an important role for those who can provide a high‐quality service to business and leisure consumers. © 1998 John Wiley & Sons, Ltd.
