Detection of probing attempts in secure ICs

2012 IEEE International Symposium on Hardware-Oriented Security and Trust, 2012
Physical attacks focus on extracting information from internal parts of IC's. One way to achieve this is by means of connecting probes to wires, so that the content of internal buses and registers can be revealed. Protection against this type of attacks exists, but usually is bulky and expensive, e.g. the shielding of secured areas. This paper presents

EM Probes Characterisation for Security Analysis

2012
Along with the vast use of cryptography in security devices came the emergence of attacks like Electro-Magnetic analysis (EMA) where the measurement of the Electro-Magnetic (EM) waves radiated from an integrated circuit are used to extract sensitive information. Several research papers have covered EMA but very few have focused on the probes used.

Researchers probe security through obscurity

Communications of the ACM, 2014
Obfuscation protects code by making it so impenetrable that access to it won't help a hacker understand how it works.

Probe into E-Commerce Security Technology

2009 International Forum on Computer Science-Technology and Applications, 2009
Among all the restraints of the development of E-commerce, the security problem of transaction has become the key element. Meanwhile all kinds of E-commerce security technologies have attracted more and more attention and study. In order to find better solutions of E-commerce security problems, such as anti-wiretapping, anti-juggling of the information,

Unifying Freedom and Separation for Tight Probing-Secure Composition

2023
The masking countermeasure is often analyzed in the probing model. Proving the probing security of large circuits at high masking orders is achieved by composing gadgets that satisfy security definitions such as non-interference (NI), strong non-interference (SNI) or free SNI.

A Low Area Probing Detector for Security ICs

2014
In this paper, a low cost, Low Area Probing Detector (LAPD) is presented. Probing or microprobing is an attack technique against integrated circuits implementing security functions, such as OTP tokens or smartcards. It allows intercepting secrets from on-chip wires as well as injecting faults for other attacks.

Private stateful circuits secure against probing attacks

Proceedings of the 2nd ACM symposium on Information, computer and communications security, 2007
We discuss the following problem: how to guarantee privacy of a circuit if an adversary can eavesdrop on its wires, where the functionality of the circuit is assumed public and the adversary attempts to discover information regarding the computation, namely, input, intermediate results and output. We present a solution by introducing a private stateful

PIT: A Probe Into Internet of Things by Comprehensive Security Analysis

2019 18th IEEE International Conference On Trust, Security And Privacy In Computing And Communications/13th IEEE International Conference On Big Data Science And Engineering (TrustCom/BigDataSE), 2019
One of the major issues which are hindering widespread and seamless adoption of Internet of Thing (IoT) is security. The IoT devices are vulnerable and susceptible to attacks which became evident from a series of recent large-scale distributed denial-of-service (DDoS) attacks, leading to substantial business and financial losses.

KERALA'S FOOD SECURITY STATUS—A PROBE

Journal of International Development, 2013
AbstractThe Indian state of Kerala had attained international acclaim for its consistently higher level of human development comparable with that of many advanced countries even with a much lower per capita income. The present paper focuses on the food security concerns in the state, which produces less than a quarter of its food grain requirements ...
