 Cadote: Compiler-Aided Development of Trusted Enclaves
 ======================================================
 
-This is the code for [my Masters Thesis](https://www.f30.me/files/masters-thesis.pdf) and our ARES 2022 paper [*Compiler-Aided Development of Trusted Enclaves with Rust*](https://doi.org/10.1145/3538969.3538972).
+This is the code for [my Masters Thesis](https://www.f30.me/files/masters-thesis.pdf) and our ARES 2022 paper [*Compiler-Aided Development of Trusted Enclaves with Rust*](https://dl.acm.org/doi/10.1145/3538969.3538972?cid=99660549531).
 It is quite hacky research-grade code, where I had to go to the limit of what is possible with an LLVM pass.
 Also, there is quite some C++ code and I'm not much of a C++ programmer.
 Sorry about that.
