Many automotive Remote Keyless Entry (RKE) systems have been successfully attacked in the last few years. The security of RKE systems is still a sensitive and crucial issue for vehicular industry. The problem needs to be essentially addressed by the fundamental fabrication weakness namely: "the manufacture can clone his own fabricated keys" and create equal units. This should not be possible...
Efficient trust management between nodes in a huge network is an essential requirement in modern networks. This work shows few generic primitive protocols for creating a trusted link between nodes by deploying unclonable physical tokens as Secret Unknown Ciphers. The proposed algorithms are making use of the clone-resistant physical identity of each participating node. Several generic node authentication...
Digital Secret Unknown Cipher (SUC) has been proposed in the last decade targeting to counteract the drawbacks of the traditional analog Physical Unclonable Functions (PUF). The SUCs, as pure-digital units, exhibit consistent operation during the whole digital unit's lifetime. This makes SUCs as PUF alternatives attractive for practical creation of clone-resistant units for a broad spectrum of applications...
Secured remote sensing is becoming a widely required technology to make certified measurements at remote sites via Internet of Things (IoT) without the need for trusted personal efforts. This is essentially required for reading huge number of meters such as consumed energy, gas, electricity or water meters. It is necessary to produce such meters at low-cost deploying standard System-on-Chip (SoC)...
Secret Unknown Ciphers (SUCs) were first introduced in [1]. Such ciphers are self-created, basically unknown ciphers within a permanent digital self-reconfiguring unit. Such self-reconfiguring non-volatile structures are expected to be available in the near future. The authors approached quite promising concepts for realizing such ciphers in Microsemi non-volatile self-reconfiguring FPGA units. This...
