Title: High-radix Modular Exponentiator for RSA using CRT
Inventor: JUNG YONG JIN
IPC: G06F7/52
Filed: 2001-03-06
Abstract: PURPOSE: A high radix RSA modular exponentiation operation device is provided to horizontally map a data dependency graph of the Montgomery algorithm when a modular multiplier, a core operator of the RSA, is implemented so that it can make it easy controlling a data flow. CONSTITUTION: The device comprises a control block, 512 bit registers, and an RSA core. The control block generates a signal for controlling the 512 bit registers, the RSA core and an exponentiation operation process according to an encoding or decoding signal. The control block generates a control signal for enabling the 512 bit registers and the RSA core to perform a 1024 bit encoding operation at an encoding process, and enabling the 512 bit registers and the RSA core to perform a simultaneous parallel decoding operation at a decoding process. The device employs the Montgomery algorithm and a CRT(Chinese Remainder Theorem) in implementing a hardware in order to enhance an operation speed rather than a conventional binary operation method. The registers and the RSA core are flexibly arranged for being switched by one control signal. When data is decoded, the registers, allocated to P and Q, private keys of a data sender and a data receiver, offer key digits necessary for an operation while performing an independent shift operation, and the RSA also independently performs a modular exponentiation operation on 512 data. The operation results are stored at result registers allocated to the P and the Q. When data is encoded, the register allocated to the P plays a role of the lower 512 bit, and the register allocated to the Q plays a role of the upper 512 bit. The two registers are serially connected and perform a shift operation as a 1024 bit register. Then the RSA core performs a 1024 modular exponentiation operation.

Abstract: PURPOSE: A reserving resources for anticipated work items via simulated work items is provided to enable the realization of high service levels and high resource utilization simultaneously, without undue constraints on the organization of the work and the organization of the resources. CONSTITUTION: A workflow-manager(150) reserves a resource for processing an anticipated real work item by sending a simulated, artificial, work item to the resource before the real work item becomes available. Any shortfall is cured by generating tokens representing that many simulated communications of that type and enqueuing, dequeuing, and assigning the tokens to agents like any other arriving communications. Any excess is cured by canceling that many outstanding, pending, tokens of that type. When a real communication of that type arrives, it is substituted for the oldest token of that type, either in queue or at an assigned agent. To be fair to all agents, an assigned token is periodically reassigned from one agent to an available another agent.
