Abstract: An encryption system and method using a set of reversible functions that iteratively reduce the message to be encrypted. In an exemplary embodiment, an encryption module can first receive a data set, or a message, to be encrypted. In a single iterative step, the message can be reduced to a smaller message through the use of a tailored first function, a reduction process. A second function can generate an extra data set based on the message, which can be essential to decrypting the message later. The iterations continue until the reduction process can no longer reduce the message. When the iterations cease, the resulting encrypted message can comprise the extra data sets output during the iterations. Because the utilized functions can be reversible, a decryption module can effect decryption by simply reversing the steps of encryption.

Abstract: A confidential datum, such as a private key used in public key signature systems, is secured in a digital wallet using a “generation camouflaging” technique. With this technique, the private key is not necessarily stored in the digital wallet, not even in an encrypted form. Instead, the wallet contains a private key generation function that reproduces the correct private key when the user inputs his or her pre-selected PIN. If the user inputs an incorrect PIN, an incorrect private key is outputted. Such private key can be configured so that it cannot be readily distinguished from the correct private key through the use of private key formatting, and/or the use of pseudo-public keys corresponding to the private key. The techniques described herein are also applicable to other forms of regeneratable confidential data besides private keys.
