TEMPEST side-channel attacks recover AES-256 encryption keys

In a recently published paper, security researchers built a miniature system capable of covertly recovering encryption keys using side-channel analysis. Fox-IT’s Craig Ramsay and Jasper Lohuis collaborated with Riscure to perform this analysis against two realistic AES-256 implementations. Specifically, the attacks were conducted using an improved antenna and signal processing equipment that cost less than … Continue reading TEMPEST side-channel attacks recover AES-256 encryption keys
