where is the key size for public key cryptography.
The results also indicate that the minimum key size for the CGT-based scheme to gain an advantage over the original method is about 2 × 104 bits.
The key size for symmetric key encryption was chosen as bytes; even though real deployments would use larger keys for high security, we chose the key size in our implementation to be compatible with the RC5 encryption algorithm available in TinySec [16].
As reported by Carman et. al [1], a middle-ranged processor such as the Motorola MC68328 "DragonBall" consumes 42 mJ (840 mJ) for RSA encryption (digital signature) and 0.104 mJ for AES when the key size for both cases is 1024 bits.
This paper presents 12 linear approximations of a single round function that succeeds in attacking ARIA version 1.0 on 7, 9, or 9 rounds for key sizes of 128, 192, or 256 bits using any of these approximations.
In our implementation, we used the AES Galois/Counter Mode (AES-GCM) symmetric encryption algorithm described in [24] – key size of 128-bit – for the exchange of confidential messages between the producers and the aggregator.
Secret keys, which are used to generate an iris-based fuzzy commitment, are directly encoded, fused with fingerprint data at feature level, and locked in the fuzzy vault scheme, achieving a GMR of approximately 98%% at a FMR of 0.01 % on the in-house MSU-DBI fingerprint [52] and the CASIAv1 iris database [49] for a key size of 208 bit.
That is, for processing a billion measurements, nowadays recommended key sizes (at least 320 bit for elliptic curve cryptography) are more than sufficient to keep our data secure.
Table 7 shows the running times of the Paillier decryption (PD), computation of c i, and the total run-time (online phase) of both the EPPCP and the IDCP for different key sizes.
It shows that the EPPCP achieves better efficiency compared to the IDCP for the large key sizes.
