Web(IBS) scheme to resist ephemeral secret leakage (ESL) attacks, called leakage-free identity- based signature (leakage-free IBS), and devised the rst secure leakage-free IBS scheme. WebFeb 19, 2014 · ABSTRACT In 2011, Zhao et al. presented a new security model of group key agreement (GKA) by considering ephemeral secret leakage (ESL) attacks. Meanwhile, they proposed a strongly secure GKA protocol under the new model.

WebOct 11, 2013 · Ephemeral secrets could be compromised if they are pre-computed and stored in insecure memory. In such a case, one can reveal the private key of the signer from the corresponding signature, termed ephemeral secret leakage (ESL) attacks. In this article, we define a novel security notion for IBS schemes to capture ESL attacks.

WebEphemeral Secret Leakage (ESL) Attack According to Section 3.2 , we assume that M A can compromise the session states and secret credentials under the CK adversary model. If the short-term secrets { r 1 , r 2 } are revealed, an S K is protected since M A cannot obtain the sensitive information, such as the random nonces { n i , b j } and the ... WebIf the ephemeral secret keys are compromised, an adversary can reveal the private key of the signer from the corresponding signature, termed ephemeral secret leakage (ESL) attacks[11].This attack is possible and widely studied recently in [11-14].
