Lightweight handover authentication with location privacy-preserving in mobile wireless networks

Enhanced pairing‐free identity‐based broadcast authentication protocol in WSN using ElGamal ECC

“…• Security analysis: Most of the existing ciphering protocols [26][27][28] presented previously are susceptible to various security perils as seen after informal security analysis. To eliminate all the possibilities of considering any existing security breaches, we have proposed the ElGamal ciphering ID shifting for secure data communication during conversation with third party.…”

“…Here, the auditor who knows the ID of cloud end‐user is said to as the third party key auditor. End‐users who use a public key need to verify the authenticity of that public key 26 . As a result, the data transmission and computational overhead of cloud end‐user are extremely high.…”

“…This paper aims to formulate a ciphering protocol for authentication during broadcasting in WSN with non‐breakable security and efficacy. The proposed ciphering protocol is highly secure, user‐friendly and appropriate for mobile client environment because of the following features: Authentication during broadcasting: The proposed ciphering protocol implements ID‐based cryptosystem in order to shield the privacy of end‐user and to preserve end‐user anonymity. Bilinear pairing‐free realization: The proposed scheme establishes a bilinear pairing‐free ciphering protocol for reduced computational tariff. Security analysis: Most of the existing ciphering protocols 26‐28 presented previously are susceptible to various security perils as seen after informal security analysis. To eliminate all the possibilities of considering any existing security breaches, we have proposed the ElGamal ciphering ID shifting for secure data communication during conversation with third party. …”

“…End-users who use a public key need to verify the authenticity of that public key. 26 As a result, the data transmission and computational overhead of cloud end-user are extremely high. If the amplified computational overhead is considerably lowered, then the issue of PKC integrated authentication will easily be resolved.…”

Attribute-Based Anonymous Handover Authentication Protocol for Wireless Networks

“…At the same time, He et al [14] did some improvement to enhance He et al 's protocol [9]. Note that He et al [15] and Liu et al [16] independently presented two efficient handover authentication protocols without involving bilinear paring and map-to-point operation.…”
