Laura Holmes
Laura Holmes (1932–2016) was a career cryptanalyst and a 2011 Inductee into the NSA Hall of Honor. Biography Holmes was born to Leonard Locke Holmes, Sr. and Dorothy Pogue Holmes and graduated in 1948 from the Margaret Brent High School. She joined the National Security Agency (NSA) where, for more than four decades, she worked at Fort Meade, Maryland as a cryptanalyst and supervisor. Career During the 1980s, her work did in cryptographic code, including against a series of challenging manual cryptosystems, allowed Holmes to build an impressive range of expertise in a variety of target languages. At Fort Meade, she analyzed many dozens of manual systems from many targets and became notable because none of them were monoalphabetic (called a substitution cipher) and each required the cryptanalyst to discover a nontrivial trick, thus making de-coding particularly difficult. In addition, many of these codes were accompanied by only small quantities of traffic resulting in f ...

Cryptanalysis
Cryptanalysis (from the Greek ''kryptós'', "hidden", and ''analýein'', "to analyze") refers to the process of analyzing information systems in order to understand hidden aspects of the systems. Cryptanalysis is used to breach cryptographic security systems and gain access to the contents of encrypted messages, even if the cryptographic key is unknown. In addition to mathematical analysis of cryptographic algorithms, cryptanalysis includes the study of side-channel attacks that do not target weaknesses in the cryptographic algorithms themselves, but instead exploit weaknesses in their implementation. Even though the goal has been the same, the methods and techniques of cryptanalysis have changed drastically through the history of cryptography, adapting to increasing cryptographic complexity, ranging from the pen-and-paper methods of the past, through machines like the British Bombes and Colossus computers at Bletchley Park in World War II, to the mathematically advanced comput ...

NSA Hall Of Honor
The Hall of Honor is a memorial at the National Security Agency headquarters in Fort Meade, Maryland. It honors individuals who rendered distinguished service to American cryptology. The Hall of Honor The Hall of Honor is located on the grounds of the National Cryptologic Museum adjacent to NSA's headquarters in Ft. Meade, MD. Created in 1999, The standards are high for induction into the Hall of Honor. The individuals honored were innovators over their entire peers or made major contributions to the structure and processes of American cryptology. Inductees Yearly, the National Cryptologic Museum Foundation recommends a slate of honorees to the National Security Agency for consideration along with nominees from other sources. 2021 * Joseph E.

Substitution Cipher
In cryptography, a substitution cipher is a method of encrypting in which units of plaintext are replaced with the ciphertext, in a defined manner, with the help of a key; the "units" may be single letters (the most common), pairs of letters, triplets of letters, mixtures of the above, and so forth. The receiver deciphers the text by performing the inverse substitution process to extract the original message. Substitution ciphers can be compared with transposition ciphers. In a transposition cipher, the units of the plaintext are rearranged in a different and usually quite complex order, but the units themselves are left unchanged. By contrast, in a substitution cipher, the units of the plaintext are retained in the same sequence in the ciphertext, but the units themselves are altered. There are a number of different types of substitution cipher. If the cipher operates on single letters, it is termed a simple substitution cipher; a cipher that operates on larger groups of letters ...

1932 Births
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * January 1 – Year of the Five Emperors: The Roman Senate chooses Publius Helvius Pertinax, against his will, to succeed the late Commodus as Emperor. Pertinax is forced to reorganize the handling of finances, which were wrecked under Commodus, to reestablish discipline in the Roman army, and to suspend the food programs established by Trajan, provoking the ire of the Praetorian Guard. * March 28 – Pertinax is assassinated by members of the Praetorian Guard, who storm the imperial palace. The Empire is auctioned off ...
