Quantum-secure message authentication via blind-unforgeability
quantum quantum access model unforgeability
2018/12/3
Formulating and designing unforgeable authentication of classical messages in the presence of quantum adversaries has been a challenge, as the familiar classical notions of unforgeability do not direc...
On the One-Per-Message Unforgeability of (EC)DSA and its Variants
signature schemes DSA ECDSA
2017/9/18
The American signature standards DSA and ECDSA, as well as their Russian and Chinese counterparts GOST 34.10 and SM2, are of utmost importance in the current security landscape. The mentioned schemes ...
A Proxy Re-Encryption Scheme with the Unforgeability of Re-Encryption Keys against Collusion Attacks
proxy re-encryption non-transferability unforgeability of re-encryption keys against collusion attacks
2016/1/6
Proxy re-encryption (PRE) schemes are cryptosystems which allow a proxy who has a reencryption
key to convert a ciphertext originally encrypted for one party into a ciphertext which
can be decrypted...
Breaking Existential Unforgeability of a Signature Scheme from Asiacrypt 2014
digital signatures forgery
2016/1/6
We show how to compute an existential forgery after querying 4 signatures on chosen messages
for a signature scheme presented at Asiacrypt 2014.
Attribute-Based Signcryption : Signer Privacy, Strong Unforgeability and IND-CCA2 Security in Adaptive-Predicates Attack
Attribute-based encryption Attribute-based signature Attribute-based signcryption
2015/12/29
An Attribute-Based Signcryption (ABSC) is a natural extension of Attribute-Based Encryption
(ABE) and Attribute-Based Signature (ABS), where we have the message confidentiality and authenticity
toge...
Existing work on data collection and analysis for aggregation is mainly
focused on confidentiality issues. That is, the untrusted Aggregator learns only
the aggregation result without divulging indi...
