Single-Chip Cryptographic Modules
This post is part of the Computer Security – Cryptography posts series.
The succeeding necessities are particular to single-chip cryptographic modules.
SECURITY LEVEL 1
There are no supplemental Security Level 1 necessities for single-chip cryptographic modules.
SECURITY LEVEL 2
In plus to the necessities for Security Level 1, the succeeding necessities shall implement to single-chip cryptographic modules for this level of security.
- The cryptographic module shall be covered with a tamper-evident coating (for instance, a tamper-evident passivation material or a tamper-evident material covering the passivation) or incorporated in atamper-evident enclosure to deter direct observation, or manipulation of the module and to provide evidence of attempts to tamper with or remove the module.
SECURITY LEVEL 3
In plus to the necessities for Security Levels 1 and 2, the succeeding necessities shall implement to single-chip cryptographic modules for this level of security:
- The module shall be covered with a hard opaque tamper-evident coating (for instance, a hard opaque epoxy covering the passivation),
- or
- The enclosure shall be enforced so that attempts at removal or penetration of the enclosure shall have a high chance of causing severe damage to the cryptographic module (id est, the module won’t function).
SECURITY LEVEL 4
In plus to the necessities for Security Levels 1, 2, and 3, the succeeding necessities shall implement to single-chip cryptographic modules for this level of security.
- The cryptographic module shall be covered with a hard, opaque removal-resistant coating with hardness and adhesion characteristics such that attempting to peel or pry the coating from the module will have a high chance of resulting in serious damage to the module (i.e., the module won’t function).
- The removal-resistant coating shall have solvency characteristics such that dissolving the coating will have a high probability of dissolving or seriously damaging the module (i.e., the module will not function).
SECURITY LEVEL 5
There are no supplemental Security Level 5 necessities for single-chip cryptographic modules.

Is there an option of doing post-graduation in cryptography?
I would search in Google for “colleges cryptography”
Massachusetts Institute of Technology
good article about Single-Chip Cryptographic Modules
What language should I master for computer cryptography ?
C++ and It is the language in which most of the open source software is written in.
C++, and Gtk if you want to build GUI’s. Theres a wealth of programming tools and compilers on POSIX type systems.
Can someone explain what is Entanglement-based quantum cryptography ? Can someone tell me how a key is transmitted in this method between Marc and Paul. Various explanations says, a device is used to produce entangled photons which is send to Marc and Paul. But how can Marc send the key to Paul, if we use an external device to generate photons. The first method of cryptopgraphy using polarised photons is straight forward. But how this one works.
Marc can’t send the key to Paul, the third party that is generating the photons must do this.
Basically the key would be generated, and Marc andPaul get 1 photon worth of the key. So when Marc picks up the phone and calls Paul, and they combine the info in their photons, they have the whole key.
Anyone observing either photon cannot get the key, and any observation of the photon affects it, and the receivers know someone else that wasn’t supposed to has looked at it, due to Heisenbergs uncertainty – when a particle is observed it is altered by the observation.
interesting post
