“…Later Zheng [3] proposed a modified signcryption technique with hash function that involves simple mathematical operations such as +,-,*,%. They have shown that their signcryption scheme reduces the computational and communication cost up to 40% compared to traditional signature then encryption [4] scheme. And also their signcryption scheme was publically verifiable but that does not provide forward secrecy.…”

“…Case 1: Consider a situation where an attacker knows p a ,p b and D which are publically available and he tries to find k, in such a case solving k from (3) is computationally infeasible by the definition of HECDLP. Case 2:Consider an equation (4) in which S, p a and R arepublically available and if an attacker wants to find K2 he needs to identify private key of the receiver d b from (5) but by the definition of HECDLP solving it is computationally infeasible. (5) Case 3: Consider an equation to find S in signcryption using HECC (6), if an attacker needs to find k he has to calculate d a but finding it is computationally infeasible both from (6) and (7).…”

The need for security is a challenging task nowadays due to the transition from wired to wireless networks, emergence of Internet of Things (IoT), Mobile Networks, Wireless Sensor Networks (WSN) and Radio Frequency Identification System (RFID). Generally wireless systems are prone to insecurity and resource (power) constraint, to deal with these challenges many solutions has been proposed in cryptography. One such important development is light weight cryptography particularly signcryption.Signcryption is a logical combination of digital signature and encryption in a single step therefore the cost of communication and computation is very less compared to the existing signature then encryption scheme. Till date many signcryption techniques were raised based on El-Gamal, RSA and Elliptic Curve Cryptography (ECC). The proposed research work highlights the limitations of existing signcryption based on ECC and it proposes the efficient light weight cryptographic scheme of signcryption based on Hyper Elliptic Curve Cryptography (HECC) and Keccak hashing. Further the proposed research work achieves all the security metrics such as confidentiality, integrity, non- repudiation, forward secrecy and public verifiability

Abstract. In the big data protecting technologies, most of the existing data protections adopt entire encryption that leads to the researches of lightweight encryption algorithms, without considering from the protected data itself. In our previous paper (FGEM), it finds that not all the parts of a data need protections, the entire data protection can be supplanted as long as the critical parts of the structured data are protected. Reducing unnecessary encryption makes great sense for raising efficiency in big data processing. In this paper, the improvement of FGEM makes it suitable to protect semi-structured and unstructured data efficiently. By storing semi-structured and unstructured datum in an improved tree structure, the improved FGEM for the datum is achieved by getting congener nodes. The experiments show the improved FGEM has short operating time and low memory consumption.

“…Authentication, integrity, and non-repudiation can be ensured through digital signature [2]- [7] and confidentiality can be assured through encryption [8]- [10] algorithms. In old mechanisms, the sender first signs the message and then encrypts them by using digital signature and encryption algorithms.…”

Abstract-It is a suitable means for multi-messages to usehybrid encryption to make a safe communication. Hybrid encryption confines encryption into two parts: one part uses public key systems to scramble a one-time symmetric key, and the other part uses the symmetric key to scramble the actual message. The quick advancement of the internet technology requires distinctive message communications over the more extensive territory to upgrade the heterogeneous system security. In this paper, we present a lightweight multi-message and multireceiver Heterogeneous hybrid signcryption scheme based on the hyper elliptic curve. We choose hyper elliptic curve for our scheme, because with 80 bits key give an equivalent level of security as contrasted and different cryptosystems like RSA and Bilinear pairing with 1024 bits key and elliptic curve with 160 bits key, respectively. Further, we validate these security requirements with our scheme, for example, confidentiality, resistance against reply attack, integrity, authenticity, nonrepudiation, public verifiability, forward secrecy and unforgeability through a well-known security validation tool called Automated Validation of Internet Security Protocols and Applications (AVISPA). In addition, our approach has low computational costs, which is attractive for low resources devices and heterogeneous environment.Keywords-Multi-receiver heterogeneous hybrid signcryption; multi-message and multi-receiver heterogeneous hybrid signcryption; hyper elliptic curve; Automated Validation of Internet Security Protocols and Applications (AVISPA)
