Decryption circuit, encryption circuit, logic cell, and method of performing a dual-rail logic operation in single-rail logic environment

摘要

A decryption circuit for generating a decrypted data signal and a complementary decrypted data signal from a key. In addition, a means for performing a linkage specification so as to generate the logic signal and the complementary logic signal from the decrypted data signal and the complementary decrypted data signal in accordance with the linkage specification. In addition, an encryption means for generating an encrypted logic signal from the key and from the logic signal.
