Abstract
According to one embodiment, a method is disclosed. The method includes generating an RSA signature of a document at a first device, performing decryption pre-calculations on the RSA signature at the first device to generate a transformed encrypted signature, transmitting the transformed encrypted signature data to a second device for final decryption.
Claims22
A method comprising:
- generating an RSA signature of a document at a first device;
- performing decryption pre-calculations at the first device to generate a transformed encrypted signature;
- and
- transmitting the transformed encrypted signature to a second device for final decryption.
A method comprising:
- receiving pre-calculated encrypted signature data at a first device from a second device;
- and
- performing final decryption of the pre-calculated decrypted signature data.
A system comprising:
- a main memory device;
- an integrated circuit (IC);
- and
- a central processing unit (CPU) having an authenticated code module (ACM) to receive pre-calculated encrypted signature data, and to perform final decryption of the pre-calculated encrypted signature data.
An article of manufacture including one or more computer readable media that embody a program of instructions, wherein the program of instructions, when executed by a processing unit, causes the processing unit to:
- generate an RSA signature of a document at a first device;
- perform decryption pre-calculations at the first device to generate a transformed encrypted signature;
- and
- transmit the transformed encrypted signature to a second device for final decryption.
A central processing unit (CPU) comprising:
- an authenticated code module (ACM) to receive pre-calculated encrypted signature data, and to perform final decryption of the pre-calculated encrypted signature data.
