Signcryption is a new paradigm in public key cryptography that simultaneously fulfills both the functions of digital signature and public key encryption in a logically single step,...
Abstract. Wireless Sensor Networks (WSN) are becoming a key technology in the support of pervasive and ubiquitous services. The previous notion of “PKC is too expensive for WSNâ€...
Certificateless public key cryptography was introduced to overcome the key escrow limitation of the identity-based cryptography. Recently, Yum1 and Lee have proposed a generic ser...
This work presents a practical public-key encryption scheme that offers security under adaptive chosen-ciphertext attack (CCA) and has pseudo-random ciphertexts, i.e. ciphertexts ...
This paper proposes an efficient approach for managing the security in WSN. Our approach uses the notion of public key cryptography in which two different keys are used for encrypt...
