Abstract:

A circuit for implementing a plurality of circuits on a programmable logic device, the circuit comprising a first circuit implemented on a first portion of the programmable logic device; a second circuit implemented on a second portion of the programmable logic device; and a control circuit coupled to the first circuit and the second circuit, the control circuit providing isolation between the first circuit and the second circuit. While the first circuit and the second circuit may comprise redundant circuits implementing a common function, the circuits may also comprise circuits which must be isolated, such as an encryption circuit and a decryption circuit implementing a cryptographic function. A method for implementing a plurality of circuits on a programmable logic device is also disclosed.

US Classification:

716111, 716116

Abstract:

A computer-implemented method of verifying isolation between a plurality of modules of a circuit design to be implemented within an integrated circuit can include identifying a first module and at least a second module of the circuit design for the integrated circuit. One or more circuit attributes indicative of isolation between the first module and the second module can be identified and compared with at least one isolation criterion. An indication of whether the first module is isolated from the second module can be output according to results of the comparison.

Abstract:

In one embodiment of the invention, a method is provided for protecting against attacks on security of a programmable integrated circuit (IC). At least a portion of an encrypted bitstream input to the programmable IC is decrypted with a cryptographic key stored in the programmable IC. A number of failures to decrypt the encrypted bitstream is tracked. The tracked number is stored in a memory of the programmable IC that retains the number across on-off power cycles of the programmable IC. In response to the number of failures exceeding a threshold, data that prevents the decryption key from being used for a subsequent decryption of a bitstream is stored in the programmable IC.
