Recently, Islam and Biswas proposed an efficient and secure ID-based remote mutual authentication with key agreement scheme. We have analyzed the security and performance of Islam and Biswas’s scheme and showed that their scheme has some pitfalls. In order to solve these problems, we have constructed an enhanced ECC remote mutual authentication with key agreement scheme and proven that the prop...

Molodtsov introduced the theory of soft sets, which can be seen as a new mathematical approach to vagueness. In this paper, we first point out that several assertions (Proposition 2.3 (iv)–(vi), Proposition 2.4 and Proposition 2.6 (iii), (iv)) in a previous paper by Maji et al. [P.K. Maji, R. Biswas, A.R. Roy, Soft set theory, Comput. Math. Appl. 45 (2003) 555–562] are not true in general, by c...

SFSDP is a Matlab package for solving sensor network localization problems. The package contains four functions, SFSDP.m, SFSDPplus.m, generateProblem.m, test SFSDP.m, and some numerical examples. The function SFSDP.m is an Matlab implementation of the semidefinite programming (SDP) relaxation proposed in the recent paper by Kim, Kojima and Waki for sensor network localization problems, as a sp...

The tumor cell-derived collagenase-stimulatory factor (TCSF) was pre viously purified from human lung carcinoma cells (S. M. Ellis, K. Nabeshima, and C. Biswas, Cancer Res., 49: 3385-3391, 1989). This protein is present on the surface of several types of human tumor cells in vitro and in vivo and stimulates production of interstitial collagenase in human fibroblasts. In this study it is shown t...

Assessment Framework Tool Sets " program as a project called " Behavioral Dependency Modeling " (BDM). Their support is acknowledged. I would like to specifically thank Sanjiv Sharma and Christopher Dean for their instructions and comments during the series of teleconferences. I would like to say thanks to my advisor, Professor Gautam Biswas for all his support, the instructions and advice he p...

In 2008, based on the two-party Diffie–Hellman technique, Biswas proposed a contributory group key exchange protocol called the Group-DH protocol. This contributory property is an important one of group key agreement. Unfortunately, in this paper we show that the proposed Group-DH protocol is not a contributory group key exchange protocol. Therefore, we propose an improved group key exchange pr...

SFSDP is a Matlab package for solving a sensor network localization problem. These types of problems arise in monitoring and controlling applications using wireless sensor networks. SFSDP implements the semidefinite programming (SDP) relaxation proposed in Kim et al. [2009] for sensor network localization problems, as a sparse version of the full semidefinite programming relaxation (FSDP) by Bi...
