Forward Secure Non-Interactive Key Exchange [PDF]
, 2014 Exposure of secret keys is a major concern when cryptographic protocols are implemented on weakly secure devices. Forward security is thus a way to mitigate damages when such an event occurs. In a forward-secure scheme, the public key is indeed fixed while the secret key is updated with a one-way process at regular time periods so that security of the ...

Forward and Backward Private Searchable Encryption for Cloud-Assisted Industrial IoT
SensorsIn the cloud-assisted industrial Internet of Things (IIoT), since the cloud server is not always trusted, the leakage of data privacy becomes a critical problem. Dynamic symmetric searchable encryption (DSSE) allows for the secure retrieval of outsourced

Cryptanalysis of AES-PRF and Its Dual
IACR Transactions on Symmetric Cryptology, 2018 A dedicated pseudorandom function (PRF) called AES-PRF was proposed by Mennink and Neves at FSE 2018 (ToSC 2017, Issue 3). AES-PRF is obtained from AES by using the output of the 5-th round as the feed-forward to the output state.

Analysis and improvement of an ID-based authenticated key agreement protocol
Tongxin xuebao, 2008 The security of a recently proposed ID-based authenticated key agreement protocol was analyzed. Although it is provably secure in the standard model, a malicious PKG （private key generator） can still obtain all of the agreed ses-sion keys, that is, it ...

Forward-secure ciphertext-policy attribute-based encryption scheme
Tongxin xuebao, 2014 To mitigate the damage of key exposure in the context of ciphertext-policy attribute-based encryption (CP-ABE). The syntax and security model of forward-secure CP-ABE was presented. Then, a concreted forward-secure CP-ABE scheme was constructed.
