In this paper we propose a digital signature scheme using a two-layer multivariate polynomial system. This scheme works like a zero-knowledge proof scheme. The algorithm can be implemented in two modes, parallel mode and series mode. As Multivariate Polynomial Cryptography (MPC) is a viable choice in the post quantum era, various algorithms based on MPC are(More)
Automatic speech recognition (ASR) has been the focus of many researchers for several years. In speech recognition system is for a computer be able to "hear, " understand," and "act upon" spoken information. The speaker recognition system viewed as working in a Analysis , Feature extraction , Modeling , Testing/Matching techniques .speech processing is to(More)
In the near future, RFID tags will become a day-to-day affair, as they are the potential substitutes for Bar Codes. Isolating a single targeted RFID tag, from a lot containing thousands of tags, demands an efficient algorithm. Binary tree walking is a commonly used technique for this purpose. In this paper, we propose an efficient variation of the binary(More)
The contribution of Stream ciphers to cryptography is immense. For fast encryption, stream ciphers are preferred to block ciphers due to their XORing operation, which is easier and faster to implement. In this paper we present a matrix based stream cipher, in which a m x n binary matrix single handedly performs the work of m parallel LFSRs. The resistivity(More)
