MIT sues Amazon over alleged AWS cryptography patent infringement

The Massachusetts Institute of Technology filed a federal lawsuit against Amazon Web Services on Friday, alleging that AWS infringes two patents covering physical unclonable function technology used for cryptographic keys. MIT says AWS uses related cloud-security technology supplied by Synopsys, which is not named as a defendant. The university is seeking unspecified monetary damages, while Amazon had not responded to the complaint.

The case creates potential legal costs and operational uncertainty for Amazon if MIT’s claims succeed. The complaint also puts AWS’s use of Synopsys-supplied security technology under scrutiny, although the financial impact is not specified.
