Nowadays cryptography is critical to all organizations. Cryptography is usually used by passwords, SSL, smart cards. Cryptographic systems can provide following services: 1) authentication, 2) non-repudiation 3) confidentiality 4) integrity. For user authentication the password should be used. The politics for password selection must be applied: the password should contain at least 8 symbols, have characters, symbols and numbers, so that it would be difficult to guess it. It is more secure to use two-factor authentication, rather relying entirely on password authentication. Non-repudiation tools are needed to prove that definite user made transaction (for example, queried statement). Only appropriate ...

Compare and contrast symmetric and asymmetric encryption

Comparison Both the symmetric and the asymmetric encryption are means of securing communication between parties, especially in an enterprise. They function through encryption of plaintext and decryption of ciphertext to promote data integrity, confidentiality, and authentication (Sasi, Dixon, and Wilson, 2014).

Contrast

The symmetric encryption uses the same key for both encryption and decryption operations. On the contrary, asymmetric encryption (public-key encryption) uses a pair of keys, one for the public and the other one for private use. The communication between parties only takes place when data encrypted with the public key corresponds to the owner of a specific private ...

1. An alternative to the Role-Based Access Controls is the development of an own solution for access control for the organization.
