Security-Performance Trade-offs in embedded systems using flexible ECC hardware

Programmable and Parallel ECC Coprocessor Architecture: Tradeoffs between Area, Speed and Security

“…No safe errors can be introduced based on our proposed scheme. In order to pass the PV, the outputs from the coordinate conversion must be correct, which means both intermediate results P 1 and P 2 must be used in order to calculate the y value at the last step of coordinate conversion. So, no safe errors can be introduced in either P 1 or P 2 .…”

“…By using the random scalar splitting scheme (K = K 1 + K 2 ) the final results have to be obtained through two steps of point operations. For the first step, we use López-Dahab projective coordinates and Montgomery Scalar Multiplication to get two results for K 1 · P and K 2 · P. If transient faults are inserted during this step, before coordinate conversion the invariant relation of intermediate point Q [0] and Q [1] (see Fig. 1) will be destroyed.…”

“…Performance, security and cost are the three important dimensions of ECC implementations. ECC accelerators should support multiple security and performance levels, allowing the system to adjust its security-performance to application-specific needs [1]. To achieve these goals, much research has been conducted targeting different aspects, and most research topics fall into two categories: efficient implementations and security analysis.…”

A security scheme for geographic information databases in location based systems

“…Next, security concerns of geographical data and required security policies are studied through the data model [8], [7]. The trade-off between security and performance in the embedded systems for cryptography implementation as a critical factor is evaluated [10]. In [9] Using geographical location as an authentication factor is studied.…”

Guest Editors’ Introduction to Security in Reconfigurable Systems Design

“…This problem has a technological dimension (how to support confidentiality with a given reconfigurable fabric) as well as a methodological, protocol-oriented dimension [Gogniat et al 2005;Drimer 2007]. -Methods are needed to quantify the trade-offs between security, performance, and power in reconfigurable circuits, in particular in the area of · 1: 3 cryptographic algorithms [Alrimeih and Rakhmatov 2007]. In addition, formally verifiable design automation techniques ensure that synthesis will maintain trust and security properties in the design [Hammarberg and Nadjm-Tehrani 2003].…”
