Non-malleable Coding for Arbitrary Varying Channels
Fuchun Lin, San Ling, Reihaneh Safavi-Naini +1
Non-malleable codes protect against an adversary who can tamper with the coded message by using a tampering function in a specified function family, guaranteeing that the tampering…
Leakage-Resilient Non-Malleable Secret Sharing in Non-compartmentalized Models
Fuchun Lin, Mahdi Cheraghchi, Venkatesan Guruswami +2
Non-malleable secret sharing was recently proposed by Goyal and Kumar in independent tampering and joint tampering models for threshold secret sharing (STOC18) and secret sharing w…
Secret Sharing with Binary Shares
Fuchun Lin, Mahdi Cheraghchi, Venkatesan Guruswami +2
Shamir's celebrated secret sharing scheme provides an efficient method for encoding a secret of arbitrary length among any players such that for a threshold…
Non-Malleable Codes with Leakage and Applications to Secure Communication
Fuchun Lin, Reihaneh Safavi-Naini, Mahdi Cheraghchi +1
Non-malleable codes are randomized codes that protect coded messages against modification by functions in a tampering function class. These codes are motivated by providing tamper…
Detecting Algebraic Manipulation in Leaky Storage Systems
Fuchun Lin, Reihaneh Safavi-Naini, Pengwei Wang
Algebraic Manipulation Detection (AMD) Codes detect adversarial noise that is added to a coded message and stored in a storage that is opaque to the adversary. We study AMD codes w…
2- and 3-modular Lattice Wiretap Codes in Small Dimensions
Fuchun Lin, Frédérique Oggier, Patrick Solé
A recent line of work on lattice codes for Gaussian wiretap channels introduced a new lattice invariant called secrecy gain as a code design criterion which captures the confusion…
