On Local Mutual-Information Privacy
Khac-Hoang Ngo, Johan Östman, Alexandre Graell i Amat
Local mutual-information privacy (LMIP) is a privacy notion that aims to quantify the reduction of uncertainty about the input data when the output of a privacy-preserving mechanis…
Secure Aggregation is Not Private Against Membership Inference Attacks
Khac-Hoang Ngo, Johan Östman, Giuseppe Durisi +1
Secure aggregation (SecAgg) is a commonly-used privacy-enhancing mechanism in federated learning, affording the server access only to the aggregate of model updates while safeguard…
Short-Packet Transmission over a Bidirectional Massive MIMO link
Johan Östman, Alejandro Lancho, Giuseppe Durisi
We consider the transmission of short packets over a bidirectional communication link where multiple devices, e.g., sensors and actuators, exchange small-data payloads with a base…
Short-packet Transmission via Variable-Length Codes in the Presence of Noisy Stop Feedback
Johan Östman, Rahul Devassy, Giuseppe Durisi +1
We present an upper bound on the error probability achievable using variable-length stop feedback codes, for a fixed size of the information payload and a given constraint on the m…
Saddlepoint Approximations for Short-Packet Wireless Communications
Alejandro Lancho, Jöhan Ostman, Giuseppe Durisi +2
In recent years, the derivation of nonasymptotic converse and achievability bounds on the maximum coding rate as a function of the error probability and blocklength has gained atte…
Peak-Age Violation Guarantees for the Transmission of Short Packets over Fading Channels
Johan Östman, Rahul Devassy, Giuseppe Durisi +1
We investigate the probability that the peak age of information in a point-to-point communication system operating over a multiantenna wireless fading channel exceeds a predetermin…
