SUMMARY:Anonymous Authorized Communication Systems
DESCRIPTION:Speaker: Adithya Vadapalli (IIT Kanpur)\n\nAbstract: \nAnonymou
 s communication systems protect users from surveillance and censorship\, b
 ut practical deployments often require mechanisms to control who can parti
 cipate and what information they can access. This creates a fundamental te
 nsion between anonymity\, access control\, and accountability. This talk p
 rovides an overview of authorized anonymous communication systems\, which
  aim to reconcile these competing goals. We will discuss the key challenge
 s\, survey the cryptographic techniques used to address them\, and highlig
 ht recent advances that enable efficient authorization\, revocation\, and 
 auditing without compromising user privacy. The talk will conclude with o
 ur recent work on Authorized Anonymous Communication Systems.\n \nBio: I
  am an Assistant Professor at the Computer Science and Engineering Departm
 ent of IIT Kanpur. I did my Ph.D. at Indiana University Bloomington. After
  my Ph.D.\, I was a Postdoctoral Fellow at the University of Waterloo in t
 he CrySP group for two years. In my research\, I build data-leak-proof sy
 stems. In creating such data-leak-proof systems\, I develop cryptographic 
 primitives and tools that have applications beyond the particular system.\
