User authentication in case of wireless sensor network is a very critical task, as sensor nodes are deployed in unattached environment and are prone to possible hostile network attacks. Any authentication protocol in WSN must be designed keeping the fact that sensor nodes have limited computing power, memory, energy and communication capabilities. In this paper,animproved user authentication protocol based on Elliptic Curve Cryptography (ECC) has been introduced for hierarchical wireless sensor networks (HWSN). This paper shows that the ECC based protocol is suitable for wireless sensor networks where higher security is demanded. Besides thisthe proposed scheme provides mutual authentication and a secret session key for communication between the user and the cluster head. It also providesan option for addition or replacement of cluster head in the network whenever there is a need. General TermsWireless sensor networks, Security.

“…Typically, elliptic curves are defined over either the integers modulo a prime number (GF(p)) or over binary polynomials (GF (2m)). An elliptic curve is a cubic equation of the form: Generally, the security of ECC relies on the difficulties of the following problems [10]. Definition 1 Given two points P and Q over Ep(a, b), the elliptic curve discrete logarithm problem (ECDLP) is to find an integer s ε Fp * such that Q = s.P.…”

Public Key Cryptography (PKC) is recently playing an essential role in electronic banking and financial transactions. Elliptic Curve Cryptography (ECC) is one of the best public key techniques for its small key size and high security and is suitable for secure access of smart cards because implementation on smart cards is challenging due to memory, bandwidth, and computation constraints. In this paper, we proposed a passwordauthenticated key agreement scheme based on ECC. Our scheme provides more guarantees in security as follows: 1) the computation and communication cost is very low; 2) a user can freely choose and change his own password; 3) the privacy of users can be protected; 4) it generates a session key agreed upon by the user and the server; 5) it provides both implicit key and explicit key confirmation; and 6) it can prevent the offline dictionary attack even if the secret information stored in a smart card is compromised. And yet, our scheme is simpler and more efficient for smart card authentication.

“…In [4], Zheng introduced the notion of signcryption in 1997, which is a cryptographic primitive that supplies both authentication and confidentiality in a reasonable logic step, at a lower price than that of the traditional signature-then-encryption approach. Many practical and novel signcryption schemes along with their applications have been proposed in the past years (such as [3,[5][6][7][8][9][10][11][12]). …”

“…For example, in 2006, Duan and Cao [8] proposed a multi-receiver ID-based signcryption for more than one receiver scenario. In 2008, Li et al [7] presented an ID-based broadcast signcryption for the application of broadcasting a message to multiple users in a secure and authenticated manner. In 2010, Liu et al [18] proposed certificateless signcryption as an extension of ID-based signcryption.…”

Identity-based signcryption is a useful cryptographic primitive that provides both authentication and confidentiality for identity-based crypto systems. It is challenging to build a secure identity-based signcryption scheme that can be proven secure in a standard model. In this paper, we address the issue and propose a novel construction of identity-based signcryption which enjoys IND-CCA security and existential unforgeability without resorting to the random oracle model. Comparisons demonstrate that the new scheme achieves stronger security, better performance efficiency and shorter system parameters.
