Information sharing and transmit has been increased exponentially in today's world of Information and Communication Technology. Cryptography is a lasting solution to save the sensitive data from unauthorized access. Finding proper cryptographic structure for wireless sensor networks (WSNs) is extremely challenging as there are some limitations on energy and memory resources of WSNs. Hence, this paper presents an efficient secret key based security architecture which aims to contribute robust security to the topic with ideas to man-in-the-middle attacks and many other hacker situations. In this scheme, singular value decomposition (SVD) of a pseudo-inverse matrix has been used for the key generation. This scheme does not require key handshaking for data transmission and reception between the nodes. The analytical results demonstrate that the proposed scheme shows a significant gain in the rank of security, and is suitable for WSNs of the modern age.
