Full disk encryption is a method of encrypting data on a hard drive, useful for easily stolen drives. There are two styles: those that encrypt the master boot record and those that don’t. Hardware-based encryption has minimal impact on system speed, while software-based encryption has a moderate impact. This type of encryption is used more […]
Secure coding aims to prevent common programming errors that can lead to security risks. Protocols and standards are used to eliminate vulnerabilities, but a balance must be struck between functionality and security. Individual programmers can use tactics such as consistency and clarity in coding. Secure coding tries to avoid easily preventable coding flaws that create […]
Cryptanalysis is the study of breaking encrypted data without a key. It is used by both malicious hackers and the military, as well as designers of cryptographic systems to find weaknesses. Different types of attacks can be used, including brute force attacks, but longer keys are less likely to be subject to this type of […]
The AES encryption algorithm is used by the US government for classified and unclassified data. It was approved as a federal government standard in 2002 and is now the only approved publicly accessible encryption system for classified documents. It consists of three separate keys of 128, 192 and 256 bits, making it virtually impossible to […]
Full disk encryption encodes all data on a disk, including operating system files and temporary files, to prevent unauthorized access. It can be software or hardware-based and provides different levels of security. Some programs can be attacked by cold boot attacks, but others offer protection against them. Full disk encryption is the encryption of data […]
Hard drive encryption protects the entire contents of a computer’s hard drive using an algorithm, but its security was challenged in 2008 due to DRAM retaining data after a power outage. The Trusted Computing Group published a standard in 2009 to address this issue. The term hard drive refers to the main memory used in […]
Data encryption is crucial for cyber security to protect against espionage. Encryption algorithms use mathematical functions and unique keys to convert plain text into unrecognizable characters. Strong encryption standards use complex functions and large keys, such as Blowfish and RSA. One of the fundamental roles of cyber security is to protect data from malicious espionage […]
Disk encryption software encrypts entire disk drives and can require separate hardware for unlocking or use deniable encryption. Some software creates hidden volumes, while others use additional hardware devices. However, disk encryption software is not immune to attacks, such as brute-force dictionary attacks or cold boot attacks. Disk encryption software is a method of full […]
Network encryption protects data from tampering and theft, reducing cybercrime and cyberterrorism. Encryption ensures privacy, integrity, authentication, and non-repudiation. Two types of cryptographic systems are symmetric key and public key. Outdated digital certificates play a role in public key encryption, such as SSL and TLS, which signal secure sites with “https”. Visitors are notified of […]
AES software uses symmetric key block cipher to encrypt data, widely used for its security and efficiency. It offers three key sizes: AES 128, AES 192, and AES 256. AES encryption is secure and efficient, but side-channel attacks can crack it on certain systems. Advanced Encryption Standard (AES) software is a security program that uses […]
The IDEA encryption algorithm is a strong encryption function based on a 128-bit key. It uses a symmetric private key approach and is used by multiple international governments. However, its patent expired in 2011 and it is unable to process at speeds sufficient for many high-speed transactions. Data encryption has been used for centuries as […]
Cipher encryption uses a key to protect information, with block and stream methods determining how encryption is applied. Symmetric ciphers use the same key for encryption and decryption, while asymmetric ciphers use different keys. Stream ciphers are constantly changing, but can be deciphered if the code repeats or the message is known. Cipher encryption is […]
Data encryption encodes plain text data into unrecognizable values for security. The Data Encryption Standard (DES) was the first standard for encrypting digital data, but was replaced by the Advanced Encryption Standard (AES) due to its small key size. Triple DES is a slower variation of DES that is still used today. Data encryption is […]
Encryption software uses algorithms to turn readable text into unreadable code, which can only be undone by a passphrase or key. The Advanced Encryption Standard (AES) is the current US government standard, while asymmetric encryption schemes use a pair of keys for added security in emails. Many encryption programs are available online, with AES-type programs […]
Data encryption protects digital data by converting it into a secret scrambled format using hashing algorithms. The AES data encryption standard is currently the highest level of encryption, requiring a 256-bit key. Cryptography has been used for centuries to hide important information. AES is a form of encryption adopted as standard in the US, replacing […]
Encryption and decryption convert electronic data into ciphertext, which is difficult to read, and back to its original form using a key. It is used to protect sensitive data during electronic transactions and interactions with government agencies. Secure transmissions are indicated by a closed padlock and “https” in the address bar. Encryption is also used […]
Encryption technology converts data into an unreadable format using a mathematical algorithm. The only way to convert it back is through a second algorithm and a special key. Encryption is common in all levels of computer use and protects data from theft. There are two types of computer encryption: data at rest and data in […]
Encryption software scrambles information for secure communication or to conceal valuable data. It incorporates knowledge from math, stats, computer science, and engineering. Hackers use it to gain access to computers. Encryption software is available for purchase or free download and can be governed by national laws. Encryption software is a type of computer program typically […]
DES encryption was the first standard for computer encryption, but its 56-bit key was quickly cracked. It was replaced by AES encryption in 2001, which offers stronger security. DES is only supported in legacy systems. Encryption is the process of creating secret messages in an attempt to hide sensitive data. In computing, there are many […]
Data encryption converts digital data into uninterpretable information. Encryption key management is the process of managing an organization’s unique encryption keys. There are two types of data encryption key techniques: asymmetric and symmetric keys. Managing encryption keys is difficult and requires best practice recommendations. All keys should expire to ensure effective key management. Data encryption […]
