In spite of previous common assumptions about the incompatibility of public key cryptography (PKC) schemes with wireless sensor networks (WSNs), recent works have shown that they can be utilized for such networks in some manner. The major challenge of employing a PKC-based scheme in a wireless sensor network is posed by the resource limitations of the tiny(More)
 Recent emergence of electronic culture uplifts healthcare facilities to a new era with the aid of wireless sensor network (WSN) technology. Due to the sensitiveness of medical data, austere privacy and security are inevitable for all parts of healthcare systems. However, the constantly evolving nature and constrained resources of sensors in WSN inflict(More)
In spite of previous widely held belief of the incompatibility of public key cryptography (PKC) schemes for wireless sensor networks (WSNs), some recent works have shown that, PKC based schemes could be implemented for such networks in some ways. The major challenge of employing a PKC scheme in wireless sensor network is posed by the limitations of(More)
In this paper, we propose a public key based security architecture for Wireless Sensor Networks (WSNs). The basic architecture comprises of two schemes; a key handshaking scheme based on simple linear operations for fast computation and an identity based cryptosystem which does not require any certificate authority. Our analysis shows that, the combined(More)
Data security is now an important part of our modern day IT security. To protect data/information from unauthorized access, we need to hide the data/information. As a result, only authorized people can read/manipulate the protected data/information. Cryptography is a study of information hiding. Based on the key used for encryption/decryption, cryptography(More)
This paper proposes a public key based management scheme for secure sensor network operation namely S-PkSec (Public Key Based Security for Sensor Networks) and emphasizes detailed comparison with some similar type of schemes. Although there was a wide held belief of the incompatibility of public key cryptographic (PKC) schemes for wireless sensor networks(More)
Steganography is the science of hiding information in digital media that seemingly harmless. LSB replacement technique is commonly used in hiding information. Exploiting modification direction (EMD) method is a high capacity technique. EMD method uses the relationship of η adjacent pixels to embed the secret data. This method can hide (2n +(More)
