A Review of Elliptic Curve based Signcryption Schemes
نویسندگان
چکیده
Signcryption is a new cryptographic approach which provides authentication and encryption simultaneously in a single logical step. The aim is to reduce the cost of signature-then-encryption approach. This cost includes computational cost and communication cost. Furthermore some signcryption schemes are based on RSA while some are based on elliptic curve. This paper provides a critical review of the signcryption schemes based on elliptic curves, since signcryption schemes based on elliptic curve cryptography saves more computational time and communication cost. Also, the elliptic curve based signcryption schemes are suitable for resource constrained applications. This work explores the advantages and limitations of the different signcryption schemes based on elliptic curves.

متن کاملA Signcryption Scheme based on Elliptic Curve Cryptography
In Public key cryptography a message is sent after applying the digital signature and encryption techniques by the sender. These techniques are used so that the message properties such as confidentiality, integrity and unforgeability are maintained and the non-repudiation can be ensured at the receiving end. The digital signatures and encryption mechanisms can be combined to form a single logic...
متن کاملIdentity Based Public Verifiable Signcryption Scheme
Signcryption as a single cryptographic primitive offers both confidentiality and authentication simultaneously. Generally in signcryption schemes, the message is hidden and thus the validity of the ciphertext can be verified only after unsigncrypting the ciphertext. Thus, a third party will not be able to verify whether the ciphertext is valid or not. Signcryption schemes that allow any user to...
