Abstract:Wireless Sensor Network has various security issues like authentication of sensor nodes and its power consumption. Therefore, we are focusing on evaluation and optimization of power consumption in wireless sensor networks using light weight cryptographic techniques. This research paper studies the certificateless cryptographic algorithms and hence develops an optimal algorithm for the same. The proposed algorithm is more efficient and secured by eliminating the concept of digital signature to make the light weight cryptographic algorithm using PKC and IBE. The simulation result shows that the proposed algorithm can achieve approximately 5-20% reduction of energy consumption with same level of security.

“…In 2014, Tsai et al [11] proposed an improved scheme. Unfortunately, the improved scheme by Tsai et al is actually secure just against normal adversary [12], and then a new CLS scheme [12] was put forward against super adversary. In addition, some other excellent CLS schemes based on the random oracle model [13][14][15] were presented to improve the performance.…”

SUMMARYCertificateless cryptography not only enjoys many advantages of identity-based cryptography (IBC) but also eliminates the fatal drawback, which is called the key escrow in IBC. Most of the early certificateless signature schemes are secure based on the random oracle model, and nowadays, more and more researchers put emphasis on the scheme based on the standard model. In 2010, Xia et al. demonstrated that the previous schemes in the standard model cannot resist the public-key-replace attack. In 2012, for the purpose of overcoming the common drawback, Yu et al. presented a new certificateless signature scheme. However, under the public-key-replace attack and malicious-but-passive key generation center attack, this scheme is proven to be vulnerable. Moreover, there are too many bilinear pairings used in this scheme, which lead to its low computation efficiency. Aiming at the weakness of the scheme byYu et al., we propose a new certificateless signature scheme, which provides stronger security and higher computational efficiency than the existing schemes. In addition, according to the concept of Girault's trust level, the new scheme can reach trust level 3.

“…'Despite the computation power of bilinear pairing is approximately bigger than the scalar multiplication over the elliptic curve group, it's considered as a primitive for most of certificateless based cryptography (e.g. [7][8][9][10][11]) including the signature schemes'. In [12], the authors proposed a certificateless signature (CLS) scheme without bilinear pairings to overcome the 'computation cost of the pairing based schemes'.…”

SUMMARY'Organization signature is a new variant of digital signature in organization transactions. It allows the employee in the organization to generate the message signature through his affiliation rather than his personal description. Certificateless public key cryptography solved the key escrow problem in identity-based cryptography, and the certificate distribution in the traditional public key infrastructure. In this paper, we present a provable secure pairing-free certificateless organizational signature scheme. Our scheme is more computationally efficient because it does not depend on pairings. The new scheme is provably secure in the random oracle model, assuming the hardness of elliptic curves discrete logarithm problem.'
