Manoj Kumar
In 2002, Chien–Jan–Tseng introduced an efficient remote user authentication scheme using smart cards. Further, in 2004, W. C. Ku and S. M. Chen proposed an efficient re…
An Improved Remote User Authentication Scheme Using Smart Cards
Manoj Kumar
In 2000, Hwang and Li proposed a new remote user authentication scheme using smart cards. In the same year, Chan and Cheng pointed out that Hwang and Li’s scheme is not secur…
Faults and Improvements of an Enhanced Remote User Authentication Scheme Using Smart Cards
Manoj Kumar
In 2000, Hwang and Li proposed a remote user authentication scheme using smart cards to solve the problems of Lamport scheme. Later, Chan- Chang, Shen- Lin- Hwang and then Chang-Hw…
A Cryptographic Study of Some Digital Signature Schemes
Manoj Kumar
In this thesis, we propose some directed signature schemes. In addition, we have discussed their applications in different situations. In this thesis, we would like to discuss the…
A Directed Threshold - Signature Scheme
Sunder Lal, Manoj Kumar
Directed signature is the solution of such problems when the signed message contains information sensitive to the signature receiver. Generally, in many application of directed sig…
A Directed -Threshold Multi-Signature Scheme
Sunder lal, Manoj Kumar
In this paper, we propose a Directed Threshold Multi-Signature Scheme. In this threshold signature scheme, any malicious set of signers cannot impersonate any other set of signers…
