The XOR operator is extremely common as a component in more complex ciphers. By itself, using a constant repeating key, a simple XOR cipher can trivially be broken using frequency analysis. If the content of any message can be guessed or otherwise known then the key can be revealed. Its primary merit is that it is simple to implement, and that the XOR operation is computationally inexpensive. A simple repeating XOR (i.e. using the same key for xor operation on the whole da… http://www.campaignmastery.com/blog/the-cypher-gate/

WebSep 5, 2024 · Encrypt using XOR Cipher with Repeating Key. Computer Architectures have predefined ASCII values & Binary forms for all printable characters, which allows us to operate bit-wise logic like XOR and most encryption/decryption algorithms depend on. The Key is XOR-operated on the plain text to produce the encrypted text. WebIn this work, we used a sensor-based True Random Number Generator in order to generate keys for a stream cipher based on a recently published hybrid algorithm mixing Skew Tent Map and a Linear Feedback Shift Register. The stream cipher was implemented and tested in a Field Programmable Gate Array (FPGA) and was able to generate 8-bit width data … orchid hospital pune

WebTable 1 shows that the lightweight ciphers can be implemented with smaller area and less energy consumption. Note that PRESENT is a 64-bit block cipher while CLEFIA and AES are 128-bit block ciphers. Generally speaking, 64-bit block ciphers can be implemented with smaller gate counts, but there are certain security limitations. Table 1.
