White-box cryptography concerns the design and analysis of implementations of
cryptographic algorithms engineered to execute on untrusted platforms. Such …

Unprotected implementations of cryptographic primitives are vulnerable to physical attacks.
While the adversary only needs to succeed in one out of many attack methods, the …

How to construct a general program obfuscator? We present a novel approach to
automatically generating obfuscated code P2 from any program P whose source code is …

The initial goal of cryptography has been to design algorithms and protocols to protect a
communication channel against eavesdropping. This has been the main activity of modern …

Method and apparatus for increasing security of a cryptographic algorithm such as
deciphering, enciphering, or a digital signature. A cryptographic algorithm and a key are …

We propose a new countermeasure to protect block ciphers implemented in leaking devices,
at the intersection between One-Time Programs and Boolean masking schemes. First, we …

Obfuscation and code encryption applied to ensure confidentiality achieve some degree of
tamper resistance due to the complexity of the analysis required to break these protection …

A cold boot attack is a type of side channel attacks which exploit the data remanence
property of Random Access Memory (RAM) to retrieve contents that remain readable for a …

Side channel attacks take advantage of the fact that the power consumption of a
cryptographic device depends on the internally used secret key. A very common …

Because of its simplicity, ease of implementation, and speed, RC4 is one of the most widely
used software oriented stream ciphers. It is used in several popular protocols such as SSL …
