Cryptography and Encryption Here Come the Computers During the early 70s, the Data Encryption Standard (DES) was developed. At the time, DES was the strongest encryption in existence and believed to have a long useful life of decades before being broken. DES used a block cipher, which is an...

It works well in 128-bit form, however, AES can use keys of 192 and 256 bits. AES is considered resistant to all attacks, except brute force. Elliptic Curve Cryptography (ECC)—the algorithm used as part of the SSL/TLS protocol which encrypts communication between websites and their ...
exploiting weaknesses in cryptographic algorithms. Legacy of DES Despite having reached the end of its useful life, the arrival of Data Encryption Standard served to promote the study of cryptography and the development of new encryption algorithms. Until DES, cryptography was a dark art confined to...
Seo, Ding, and Bertino [54] proposed an efficient encryption key management mechanism for end-to-end security in an AMI by applying certificateless public key cryptography for SM key management. This approach eliminates the overhead due to certificate management by the utility company. Table 6 ...

Advanced Encryption Standard (AES) Data Encryption Standard (DES) Triple DES (TDES) Twofish We’ll look at each of these shortly. Asymmetric encryption This method of encryption is known aspublic key cryptography. In asymmetric encryption, two keys are used: a public key and a private key. ...
What are the Different Types of Cryptography? Three main types of cryptography or cryptosystems can be used to protect data transmissions: 1. Symmetric Encryption In symmetric cryptography, both the sender and receiver use the same private key to encrypt and decrypt the message simultaneously. Without...
