Samsung Electronics first mobile phone that operates on solar energy

Samsung Electronics launched its first mobile phone that operates on solar energy, the “Solar Crest” (E1107). It gives its users the opportunity to charge the battery wherever there is a source of solar energy, when sources of electricity are not available.

The danger awaiting behind a screensaver

When we’re talking about your computer security, the most dangerous online activities are searching for screensavers, the lyrics of songs and different stuff for free.
The report prepared by McAfee Inc., a firm specialize in Internet security, looks like hackers know what users search most and using sophisticated search programs , they can [...]

Plasma and LCD? Were. The future is seen in the OLED technology

Currently almost a necessity in every living room, LCD televisions and plasma could be soon take the path cathode tube tv’s have already taken. According to manufacturers, a new generation of super-slim screens will revolutionize the home Entertainement.

Development of a Cryptographic Module

A proper development process provides assurance that the implementation of a cryptographic module corresponds to the module functional specification and Security Policy, that the cryptographic module is maintainable, and that the validated cryptographic module is reproducible.

We specifies the security requirements for the representation of a cryptographic module’s security functionality at various levels of abstraction from the functional specification to the implementation [..]

The following requirements shall apply to cryptographic

Digital Data Preservation | Program CD and DVD Archiving

Do:

• Handle discs by the outer edge or the center hole.
• Use a non solvent-based felt-tip permanent marker to mark the label side of the disc.
• Keep dirt or other foreign matter from the disc.
• Store discs upright (book style) in plastic cases specified for CDs and DVDs.
• Return discs to storage cases immediately after use.
• Leave discs in their packaging (or cases) to minimize the effects of environmental changes.
• Open a recordable disc package only when [..]

The Elliptic Curve Digital Signature Algorithm (ECDSA)

Public-Key Cryptography Standard (PKCS)
Public-Key Cryptography Standard (PKCS) #1, RSA Cryptography Standard, defines mechanisms for encrypting and signing data using the RSA algorithm. PKCS #1 v2.1 specifies
two digital signature processes and corresponding formats:

1. RSASSA-PKCS1-v1.5 and
2. RSASSA-PSS.

Both signature schemes are Approved for use, but additional constraints are imposed beyond those specified in PKCS #1 v2.1.

1. Implementations that generate RSA key pairs shall use the RSA criteria and the method in B.3.2 to generate those key [..]

RSA Key Pair Generation

An RSA key pair consists of an RSA private key, which is used to compute a digital signature, and an RSA public key, which is used to verify a digital signature. An RSA key pair used for
digital signatures shall only be used for digital signatures, not for other purposes (e.g., key establishment).

An RSA public key consists of a modulus n, which is the product of two positive prime integers [..]

DSA Signature Verification and Validation

Signature verification may be performed by any party (i.e., the signatory, the intended recipient or any other party) using the signatory’s public key. A signatory may wish to verify that the computed signature is correct, perhaps before sending the signed message to the intended recipient.

The intended recipient (or any other party) verifies the signature to determine its authenticity.

Prior to verifying the signature of a signed message, the domain parameters, and [..]

Digital Signatures – Key Pair Management

The secure use of digital signatures depends on the management of an entity’s digital signature key pair as follows:

1. The validity of the domain parameters shall be assured prior to the generation of the key pair, or the verification and validation of a digital signature .
2. Each key pair shall be associated with the domain parameters under which the key pair was generated.
3. Key pairs shall only be used to generate [..]

The Digital Signature Algorithm (DSA)

DSA Parameters
A DSA digital signature is computed using a set of domain parameters, a private key x, a permessage secret number k, data to be signed, and a hash function. A digital signature is verified using the same domain parameters, a public key y that is mathematically associated with the private key used to generate the digital signature, data to be verified, and the same hash function that was used [..]
