Abstract: A virtual private network (VPN) extends a private network across a public network, such as the Internet. The purpose of this research study is to implemented ATHS3 stream cipher and VEA ...

Zero-correlation linear cryptanalysis is an important method to analyze the security of block ciphers. But there are few works on zero-correlation linear attacks combined with the related-key setting.

A pure-Python implementation of the AES block cipher algorithm and the common modes of operation (CBC, CFB, CTR, ECB and OFB). Since most of the modes of operations require data in specific ...

A proprietary algorithm developed by RSA Data Security, Inc., RC2 is an alternative to DES. The algorithm expands a single message by up to 8 bytes. RC2 is a block cipher that encrypts data in blocks ...

Sony announced late last week that they have invented a new encryption mechanism known as "CLEFIA," a block cipher algorithm designed to help content producers deliver "advanced copy protection" with ...

A formula used to turn ordinary data, or "plaintext," into a secret coded message known as "ciphertext." The ciphertext can reside in storage or travel over unsecure networks without its contents ...

We are developing custom cryptographic modules for potential clients located in South Korea. These include block cipher algorithms such as SEED, ARIA, HIGHT, and LEA. For ECB mode, both the SEED and ...
