“…Сравните в этой связи текст (4), написанный разборчивым, крупным почерком с ровны-ми буквами, и, например, автограф (7). Именно почерк, как считают графологи [15], может многое сказать о личности: вскрыть ее психологические особенности, отношения с социальной средой, влияние профессии и даже установить связь с национально-стью. На данном вопросе мы останавливаться не будем, так как он находится вне зоны линг-вистического исследования.…”

“…These issues are still with us and continue to require aggressive design to reduce their impacts. Smyslov [1999] describes an API to cryptographic functions, the main purpose of which is to separate cryptographic libraries from applications, thus allowing independent development. Our service API is similar at a high level, although several differences were dictated by the need to support actual hardware accelerators and allow it to be used efficiently by protocols such as IPsec and SSL as we discuss in Section 3.…”

Cryptographic transformations are a fundamental building block in many security applications and protocols. To improve performance, several vendors market hardware accelerator cards. However, until now no operating system provided a mechanism that allowed both uniform and efficient use of this new type of resource.We present the OpenBSD Cryptographic Framework (OCF), a service virtualization layer implemented inside the operating system kernel, that provides uniform access to accelerator functionality by hiding card-specific details behind a carefully designed API. We evaluate the impact of the OCF in a variety of benchmarks, measuring overall system performance, application throughput and latency, and aggregate throughput when multiple applications make use of it.We conclude that the OCF is extremely efficient in utilizing cryptographic accelerator functionality, attaining 95% of the theoretical peak device performance and over 800 Mbps aggregate throughput using 3DES. We believe that this validates our decision to opt for ease of use by applications and kernel components through a uniform API and for seamless support for new accelerators.We are grateful to Global Technologies Group, Inc. for providing us with two XL-Crypt (Hifn 7811) boards, one Hifn 6500 reference board, and one Hifn 7814 reference board. We are also grateful to Network Security Technologies, Inc. for providing us with two Hifn 7751 boards, one Broadcom 5820 board, and two Broadcom 5805 boards. In addition, Network Security Technologies funded part of the original development of the device-support software.

We identify some of these limitations through a set of measurements focusing on application-layer cryptographic protocols such as SSL. We offer several suggestions for improvements and directions for future work. We provide experimental evidence of the effectiveness of a new approach which we call operating system shortcutting. Shortcutting can improve the performance of application-layer cryptographic protocols by 27% with very small changes to the kernel.
