Batch Authentication Method of Elliptic Curve Digital Signature Algorithm under Implicit Certificate

Abstract

The invention discloses a batch authentication method of an elliptic curve digital signature algorithm under an implicit certificate. The result of the sum of the product of the inverse of the second parameter of the signature of the data and the digest value of the data to be authenticated and the product of the corresponding base point on the elliptic curve" plus "the second parameter of the signature of each data to be authenticated The sum of the inverse of the product of the x-coordinate value of the first parameter of the signature, the digest value of the part to be signed of the implicit certificate, and the reconstruction factor of the public key of the data sender" plus "the signature of each data to be authenticated" The result obtained by the product of the inverse of the second parameter of the signature and the x-coordinate value of the first parameter of the signature and the product of the public key of the certificate center", if so, the data packets in this batch are legal and pass the authentication, otherwise Not certified. The batch authentication method proposed by the present invention can obviously improve the system throughput rate.

Description

technical field [0001] The invention relates to the field of information security, in particular to a batch authentication method of an elliptic curve digital signature algorithm under an implicit certificate. Background technique [0002] Data in computers and the Internet are easily intercepted and tampered by malicious users. In order to protect data, the field of information security puts forward the requirements of data confidentiality, data integrity, data authentication and data accountability. [0003] There are two keys in the digital signature algorithm: the private key and the public key. The private key is used to generate a signature for the data and needs to be kept private, and the public key is used to verify the signature and be disclosed to anyone in the system. Data authentication usually includes two processes, one is that the sender uses his private key to generate a signature for the data, and the other is that the receiver uses the sender's public key ...
