title = "Traitor Tracing with N1 / 3 -Size Ciphertexts and O(1)-Size Keys from k-Lin",
abstract = "We present a pairing-based traitor tracing scheme for N users with |pk|=|ct|=O(N1/3),|sk|=O(1). This is the first pairing-based scheme to achieve | pk| · | sk| · | ct| = o(N). Our construction relies on the (bilateral) k-Lin assumption, and achieves private tracing and full collusion resistance. Our result simultaneously improves upon the sizes of pk, ct in Boneh–Sahai–Waters [Eurocrypt {\textquoteright}06] and the size of sk in Zhandry [Crypto {\textquoteright}20], while further eliminating the reliance on the generic group model in the latter work.",
