3.3.1 Security of data storage and processing
1. Security of data transmission:
Our team seriously approached the issue of safe storage and data backup, ensuring
the maximum level of protection of transmitted data.
a) Security of data transmission is provided by two factors:
1. Using SSL as the main layer for data transfer;
2. Application of http/2 technology on the server side increases not only
performance, but also a level of security.
б) We use only complex keys for internal data transfer, the whole transfer
within the infrastructure is carried out with using RSA encryption (US Pat. No. 4,405,829)
2. Security of Logging In is provided by two levels of verification:
a) Verification of user data by authorization
Signature is a HMAC-SHA256 encoded message containing nonce, customer ID
and API key. The HMAC-SHA256 code must be generated using a secret key that
was generated with your API key. This code must be converted to it’s
hexadecimal representation (64 uppercase characters).
б) Abstraction of the method of hashing passwords:
The present invention is a device for and method of generating a hash value for a message
by padding the message, loading the padded message into a first shift register that
generates values according to a first rule of motion, initializing eight registers a, b, c, d, e, f,
g, and h with user-definable values; converting the contents of the registers to:
hj=gj−1; gj=fj−1; fj=ej−1; ej=dj−1+T1, where T1=hj−1+Σ1(ej−1)+Ch(ej−1, fj−1, gj−1)+Kj+Wj;
dj=cj−1; cj=bj−1; bj=aj−1; и aj=T1+T2, where T2=Σ0(aj−1)+Maj(aj−1, bj−1, cj−1);
computing:
H1(j)=a+H1(j−1); H2(j)=b+H2(j−1); H3(j)=c+H3(j−1);
H4(j)=d+H4(j−1); H5(j)=e+H5(j−1); H6(j)=f+H6(j−1);
H7(j)=g+H7(j−1); и H8(j)=h+H8(j−1);
and either performing additional conversions of the registers or returning (H1(j), H2(j),
H3(j), H4(j), H5(j), H6(j), H7(j), H8(j)) as the hash value of the message.
3. Data Storage
To ensure the highest possible level of security for our clients, we addressed the issue of
improving the quality of data storage. For this purpose, we are developing a combined
decentralized system.
a. Storage of personal data
By using the cryptosystem aes128, the data is stored in an encrypted form.
b. The storage of documents
Is also protected by an additional level of hashing of the disk structure, which makes it
impossible to predict a series of documents.
c. Distribution of data
We do not store all information on one server, the information is shared between
the storage server and the database server.
d. Storage of private keys
Our system allows for distributed key storage on services with increased security.
The distribution of information occurs between the services x, y.
AES: high-level struscture
e. Encryption of PGP data
We started implementing an additional level of security - PGP (Pretty Good Privacy)
encryption to ensure confidentiality and authentication of the files that you upload send
to us.
f. Data backup
IGT-CRYPTO is equipped with two levels of data reservation, which allows to save both
earlier events and the recent ones.
