Towards security without secrets
Physical Unclonable Functions (PUFs) are a promising new cryptographic primitive that leverage manufacturing variation to create unclonable secrets in embedded systems. In this case, the secret is no longer stored permanently in digital form, but rather as the physical properties of the manufactured chip. Further, the recent proposal of "Public Model Physical Unclonable Functions" (PPUFs) does ...
متن کاملExchanging Secrets without Using Cryptography
We consider the problem where a group of n nodes, connected to the same broadcast channel (e.g., a wireless network), want to generate a common secret bitstream, in the presence of an adversary Eve, who tries to obtain information on the bitstream. We assume that the nodes initially share a (small) piece of information, but do not have access to any out-of-band channel. We ask the question: can...
متن کاملCryptography without (Hardly Any) Secrets ?
The absolute privacy of the secret-keys associated with cryptographic algorithms has been the corner-stone of modern cryptography. Still, in practice, keys do get compromised at times for a variety or reasons. A particularly disturbing loss of secrecy is as a result of side channel attacks. These attacks exploit the fact that every cryptographic algorithm is ultimately implemented on a physical...
متن کاملSafeDeflate: compression without leaking secrets
CRIME[1] and BREACH[2] attacks on TLS/SSL leverage the fact that compression ratio is not hidden by encryption to recover content of secrets. We introduce SafeDeflate—a modification of a standard Deflate algorithm which compression ratio does not leak information about secret tokens. The modification is compatible with existing Deflate and gzip decompressors. We introduce a model in which attac...
متن کاملJam Resistant Communications without Shared Secrets
Information security is only attained when all four of the classic information assurance goals confidentiality, integrity, authenticity, and availability – are attained. The work presented focuses exclusively on the availability goal; in particular, maintaining the availability of the physical layer link in an omnidirectional wireless communications system. Hostile jamming is a direct attack on...
