This course introduces cryptography by addressing topics such as ciphers that were used before World War II, block cipher algorithms, the advanced encryption standard for a symmetric-key encryption adopted by the U.S. government, MD5 and SHA-1 hash functions, and the message authentication code. The course will focus on public key cryptography (as exemplified by the RSA algorithm), elliptic curves, the Diffie-Hellman key exchange, and the elliptic curve discrete logarithm problem. The course concludes with key exchange methods, study signature schemes, and discussion of public key infrastructure. Note: It is strongly recommended that you complete an abstract algebra course (such as the Saylor FoundationĺÎĺ_ĺĚĺ_s MA231) before taking this course. Upon successful completion of this course, students will be able to: explain how symmetric and asymmetric key ciphers work; list and define cryptographyĺÎĺ_ĺĚĺ_s goals; list and define the most common classical ciphers; explain the workings of mechanical ciphers Enigma and Lorenz; describe the principles of substitution-permutation networks; describe the algorithms for data encryption and the advanced encryption standard; describe and use the MD5 and SHA-1 hash functions; explain the idea behind public key cryptography; use the RSA cryptography system by applying it to practical problems; test whether the large integer is prime with the mathematical tools presented in this course; define the elliptic curve and use it in cryptography; explain the Diffie-Hellman key exchange; describe the most common signature and autokey identity schemes; describe the conceptual workings of public key infrastructure.

This course seeks to develop a nuanced understanding of the scope of cultural and literary expression in the late 19th and the first half of the 20th centuries.

In addition to literary modernism, the course will also take a brief look at the cultural production of modernism in art, music, architecture, cinema, philosophy, and drama. Upon completion of this course, students will be able to: Define the terms modernism and modernity and explain the similarities and differences between these terms using specific works to illustrate comparison and contrast; List and explain the importance of a variety of social, cultural, and historical developments leading up to and occurring during the modern period; Cite and analyze the meaning of primary works of literature, poetry, art, music, architecture, cinema, philosophy and drama to illustrate the principle characteristics of modernism; Compare and contrast the literatures of both France and England from the start of the modern era (i.e., the turn of the twentieth century); Explain the impact of the Great War upon the development and expression of a variety of literary and artistic forms and especially on poetry in a number of genres; Describe the aftermath of World War I and its variety of effects upon literature and art and especially upon the poetry of T.S. Eliot and the novels of Virginia Woolf and Ernest Hemingway; Define High Modernism and give examples of the tenets, ideals, and even the contradictions and self-contradictions of this movement in history and literature (and especially in both its Irish and British contexts); Define the terms postmodernism and deconstruction as well as the phrase Magical Realism and identify the most important characteristics of the movements, fields, theories, and texts associated with these terms; Explain the premises of postcolonial literature and literary theory and identify, describe, compare, and contrast postcolonial texts from range of national origins.

The period between the Renaissance and the Modern Era are referred to as the long 18th and 19th centuries, meaning that they span from around 1680-1830 and 1775-1910 - a time in which so many literary movements and cultural changes took place. In this course, the student will examine these formative cultural and literary developments such as the Enlightenment and Restoration Literature; the Rise of the Novel; Romanticism; and the Victorian Period. The student will identify and contextualize the principal characteristics of each of these movements/developments by reading representative texts. Upon completion of this course, students will be able to: identify the major literary trends of the 18th and 19th century, from Restoration comedy and satires through Victorian poetry and prose; outline the major developments in philosophical thought during the Enlightenment and identify these strains of thought in works like Voltarie's Candide; identify the factors that led to the rise of the novel as a literary form; identify the specific traits that characterize early sentimental, Gothic, and picaresque novel; describe the political factors that led to the popularity of Romanticism; describe the shift in thought that led to the split between Romanticism and Enlightenment; identify the themes, conventions, and tropes of Romantic poetry; define and explain the significance of the term/concept of ĺÎĺĺĺŤthe Romantic imagination; define the political, social, and economic factors that led to the surge in popular Victorian fiction; explain the significance of poetic experimentation in the 19th century works of writers like Tennyson, Hopkins, and Browning.

At the outset of the 16th century, Europeans tended to dismiss English literature as inferior to continental literary traditions; the educated Englishman was obliged to travel to the continent and speak in other languages in order to culture himself. By the end of the Renaissance, however, some of the greatest works in the English language from Shakespeare's dramas to Thomas More's Utopia had been written. In this course, the student will read and examine these works, situating them within their socio-historical and literary contexts, while attempting to determine how the art of English language and letters came into its own during this dynamic period. (English Literature 202)

In this course, the student will consider Dante's literature for its stylistic and thematic contributions to the body of Medieval and Italian literature, as well as for its inventive appraisal of Christianity. First, the student will examine the context of Dante's life and works, followed by taking a look at some of Dante's shorter works. Then, the student will devote the majority of the course to the study of Dante's masterpiece,The Divine Comedy. Upon completion of this course, students will be able to: summarize Dante's philosophy on the use of language in literature; identify Dante's attitude towards the relationship between Church and State based on readings from his essays; complete an autobiographical reading of Dante's work, with attention to the influence that specific romantic, political, and religious aspects of his life had on his texts; define important terms related to the study of Dante's work specifically, the poetic devices on which he relied most frequently; identify the structural aspects of The Divine Comedy, and in particular discuss the importance of the overarching circular structure of the text; point to the major biblical, historical, and literary allusions in The Divine Comedy and discuss the significance of these references; perform a cogent reading of the important symbols in Dante's texts (i.e. the presence of light, fire, and roses); critically discuss the key themes in Dante's writings, such as the narrator as pilgrim, divine judgment, and the physical reality of hell.

In this lecture, Professor Paul Fry examines trends in African-American criticism through the lens of Henry Louis Gates, Jr. and Toni Morrison. A brief history of African-American literature and criticism is undertaken, and the relationship of both to feminist theory is explicated. The problems in cultural and identity studies of essentialism, “the identity queue,” expropriation, and biology are surveyed, with particular attention paid to the work of Michael Cooke and Morrison’s reading of Huckleberry Finn. At the lecture’s conclusion, the tense relationship between African-American studies and New Critical assumptions are explored with reference to Robert Penn Warren’s poem, “Pondy Woods.”

In this course, the student will study the history of Eastern (Orthodox) Christian art.
