摘要： A method and device for using a partial public key in a cryptosystem. The cryptosystem may be based on a group, such as an elliptic curve over a finite field. The device includes a first memory for storing system parameters of the cryptosystem and a second memory for storing a portion of a public key of the cryptosystem. The device receives the complete public key, or the remainder of the public key, via communication with another device. The received portion of the public key is used to form a validated public key. A processor of the device uses the validated public key for encrypting messages and/or verifying signatures. The size of the second memory is reduced since only part of the public key is stored.

摘要： Communication and validation of information transfer from a transmitter to a receiver is achieved by generating a cipher (400) from a message m (410) using parameters of an elliptic curve, a generator point P (406) on the elliptic curve and a public key Q (416) of the receiver. The cipher includes a first element that is the product kP of a random number k (404) with the generator point P and a second element that is the product of m and the x-coordinate of the product kQ. The message m is generated from two mathematically independent representations of the information and, optionally, a random number. The cipher is communicated to the receiver and decoded to recover a message m′ (502). A validation token (500) is generated by the receiver and passed to the transmitter, which validates communication of the information to the receiver if the product mkQ is equal to the validation token.

摘要： A system and method for controlling access by a user to an embedded device. A protected access port, integral with the embedded device, includes an access manager and a level controller. The access manager issues a challenge phrase using a public key of the embedded device in response to a request by a user device to access the embedded device and determines the veracity of the user's response to the challenge phrase. A secure server stores a private key corresponding to the public encryption key of the embedded device and is operable to authenticate the user credentials and issues the response to the challenge phrase dependent upon the private key of the embedded device.
