Efficient Identity Based Public Verifiable Signcryption Scheme
Prashant Kushwah, Sunder Lal
Signcryption is a cryptographic primitive which performs encryption and signature in a single logical step. In conventional signcryption only receiver of the signcrypted text can v…
An Efficient and Publicly Verifiable Id-Based Multi-Signcryption Scheme
Munendra Agrawal, Prashant Kushwah, Sunder Lal
Multi-signcryption is used when different senders wants to authenticate a single message without revealing it. This paper proposes a multi signcryption scheme in which no pairing i…
Some Proxy Signature and Designated verifier Signature Schemes over Braid Groups
Sunder Lal, Vandani Verma
Braids groups provide an alternative to number theoretic public cryptography and can be implemented quite efficiently. The paper proposes five signature schemes: Proxy Signature, D…
Identity Based Strong Designated Verifier Parallel Multi-Proxy Signature Scheme
Sunder Lal, Vandani Verma
This paper presents a new identity based strong designated verifier parallel multi-proxy signature scheme. Multi-Proxy signatures allow the original signer to delegate his signing…
An Identity Based Strong Bi-Designated Verifier (t, n) Threshold Proxy Signature Scheme
Sunder Lal, Vandani Verma
Proxy signature schemes have been invented to delegate signing rights. The paper proposes a new concept of Identify Based Strong Bi-Designated Verifier threshold proxy signature (I…
New ID Based Multi-Proxy Multi-Signcryption Scheme from Pairings
Sunder Lal, Tej Singh
This paper presents an identity based multi-proxy multi-signcryption scheme from pairings. In this scheme a proxy signcrypter group could authorized as a proxy agent by the cooprat…
