| Abstract: |
We analyze a recently published lightweight encryption scheme for fingerprint images and discuss several shortcomings. A low-cost attack on this scheme is proposed, which allows access to the full plaintext for most given ciphertexts. We give some recommendations for improvements of the encryption scheme, but conclude that the analyzed scheme remains insecure. |
