Dismantling SecureMemory, CryptoMemory and CryptoRF
The Atmel chip families SecureMemory, CryptoMemory, and CryptoRF use a proprietary stream cipher to guarantee authenticity, confidentiality, and integrity. This paper describes the cipher in detail and points out several weaknesses. One is the fact that the three components of the cipher operate largely independently; another is that the intermediate output generated by two of those components is strongly correlated with the generated keystream. For SecureMemory, a single eavesdropped trace is enough to recover the secret key with probability 0.57 in 239 cipher ticks. This is a
