Efficient Certificateless Online/Offline Signature
Public key cryptography usually is computationally more expensive than symmetric key systems. Due to this low power or resource constrained devices cannot make use of public key cryptosystems easily. There is a need for high security in these devices since many of these devices perform complex tasks which includes interaction with third party cloud infrastructures. These cloud infrastructures a...
متن کاملA Revocable Online-Offline Certificateless Signature Scheme without Pairing
Certificateless Public key Cryptography is a widely studied paradigm due to its advantages of not having the key-escrow problem and the lack of use of certificates. Online-Offline signature schemes are extremely relevant today because of their great practical applications. In an online-offline signature scheme all the heavy computation is done on powerful processors and stored securely in the o...
متن کاملAn Efficient Certificateless Signature Scheme
Certificateless public key cryptography (CLPKC) is a paradigm to solve the inherent key escrow problem suffered by identity-based cryptography (IBC). While certificateless signature is one of the most important security primitives in CLPKC, there are relatively few proposed schemes in the literature. In this paper, we manage to construct an efficient certificateless signature scheme based on th...
متن کاملAn Improved Online/Offline Identity-Based Signature Scheme for WSNs
Online/offline signature schemes allow the signer to generate an online signature in real-time from a precomputed offline signature when presented with a document. Such schemes are particularly useful in resource-constrained wireless sensor network applications. In this paper, we describe an identity-based online/offline signature scheme based on bilinear maps, and prove the security of the sch...
متن کاملEfficient Certificateless Online/Offline Signature with tight security
Since public key cryptography is usually build using computationally expensive operation, it has been out of reach for resource constrained and low power devices. Today there are a large number of low power devices in use and they perform complex tasks. There is need for light weight cryptography having high security and low communication overhead. Online/Offline schemes are well suited for thi...
