Abstract

Techniques are described for performing decryption using a key-specific decryption engine. A message including an encrypted data portion is received. The encrypted data portion is formed by performing a symmetric encryption operation using a symmetric key. The encrypted data portion is decrypted using a key-specific decryption engine which does not use the symmetric key as an input. Also described are techniques for generating the key-specific decryption engine which may be implemented using boolean functions determined for the symmetric key.
