- C4CS Lite

Do you have any problems like this?

Focus Systems will solve that problem!

When developing a system, I would like to consider a security module that provides peace of mind.

I want to complete the security module with one product.

01: Pursue safety by obtaining certification from a third-party organization

C4CS Lite meets the security requirements for cryptographic modules according to American standards.
Additionally, as a domestic manufacturer, we provide flexible support tailored to our customers, so you can feel safe in terms of both technology and support.

02: Equipped with a wide range of cryptographic modules

C4CS Lite provides a set of various modules necessary for security, so there is no need to procure each module individually.

Features of C4CS Lite

■Compliant with American standards, safe for public institutions and in-house use
C4CS Lite has obtained FIPS140-2* certification issued by NIST (National Institute of Standards and Technology).
FIPS140-2 is a security requirement for cryptographic modules, so C4CS Lite, which meets the requirements, can be used with confidence in important systems of public institutions and customers.

*Depending on the environment and algorithm used, operation may not be as certified.

 

■Covering security modules necessary for the system
C4CS Lite has all the security modules necessary for the system, including encryption (common key/public key), hash functions, secret sharing, and key generation.

How to Use

■File encryption <br />You can encrypt each file, and any file that is general digital data can be encrypted.

 

■Memory encryption <br />Data expanded in memory can be encrypted, and the data capacity does not change before and after encryption, making memory management easy.
