“…In our experiments we intend to compare RAM to other well-known methods for dealing with misalignment: Static Alignment [9], SW-DPA [6] and Elastic Alignment [10]. We compare first-order success rates of CPA after performing the different alignment techniques applied to measurements taken from a software DES implementation.…”

“…Elastic Alignment [10] attempts to match each sample in a target trace to samples in the reference trace. It can match sequences of samples in the target trace to a single sample in the reference trace, and vice versa.…”

“…The two main parameters of this method are the number of cycles to average (the window size) and the number of samples per one clock cycle. In [10] it was shown that SW-DPA performs fairly well. However when an unstable clock is used the performance drops drastically.…”

Abstract. Several countermeasures against side-channel analysis result in misalignment of power traces, in order to make DPA more difficult. In this paper we propose a new algorithm to align the measurements after this desynchronizing through the variations of the internal clock, random delays, etc. The algorithm is based on the ideas of SIFT and U-SURF algorithm that were originally proposed for image recognition. The comparison with other known methods favors our solution in terms of efficiency and computational complexity.

This paper describes practical differential power analysis attacks. There are presented successful and unsuccessful attack attempts with the description of the attack methodology. It provides relevant information about oscilloscope settings, optimization possibilities and fundamental attack principles, which are important when realizing this type of attack.The attack was conducted on the PIC18F2420 microcontroller, using the AES cryptographic algorithm in the ECB mode with the 128-bit key length. We used two implementations of this algorithm -in the C programming language and in the assembler.

Failure of deterministic encryption algorithms against various attacks mostly occurs due to the use of fixed and deterministic methods for encrypting, decrypting, and key production. Because the key production in these algorithms is performed functionally and deterministically, there is a relation between the keys and their length that makes the differential analysis of the keys possible. Moreover, the fixed length and values of the keys make these algorithms unsafe against exhaustive key searches. In this study, a block cipher algorithm called indefinite block ciphering based on variable and great length key which belongs to probabilistic (nondeterministic) family is presented. In this algorithm, the key depends on the plain text and is produced indecisively by a random number and the connectivity of the different parameters. On the other hand, the plain text is divided into blocks with size of random number. The proposed algorithm was evaluated, and the results were compared with those of the deterministic and other nondeterministic algorithms. This comparison was indicative of the high performance and security of the new algorithm with respect to the other approaches.
