SECURITY ENHANCEMENT OF INFORMATION USING MULTILAYERED CRYPTOGRAPHIC ALGORITHM

Abstract

In response to the rising concern for the safety of data while it is being sent across computer networks, a
number of different types of encryption solutions have came into being. An encryption standard known as the AES
was developed by the National Institute of Standards and Technology (NIST) ensure the safety of data encrypted
electronically. The definition that is provided in the previous publication, FIPS Publication 197, is in accordance
with the Federal Information Processing Standards standards. encrypt and decode 128-bit blocks, the AES employs
cipher keys that are 128 bits wide (AES128). This may be accomplished successfully.Within the scope of this
investigation, the AES128 encryption algorithm was proposed as a potential hardware implementation strategy. By
virtue of the fact that it creates the round keys at the same time as the encryption, the pipelined solution that was
presented stands out as particularly noteworthy, do several rounds of encryption, these round keys are used. The
overall amount of time required to encrypt a plaintext block as well as the amount of time that passes between
encryption rounds are both significantly reduced as a result of this consideration. As a consequence of this, the
throughput of message encryption is increased as a result.
