Abstract: Methods and systems for generation of randomized messages for cryptographic hash functions are described herein. The method includes obtaining a random value in a binary bit form for randomizing a message. The method also includes splitting the message into multiple message blocks, where a length of each of the multiple message blocks is based on a length of the random value and a block length of a compression function. The method further includes prepending and appending each of the multiple message blocks with at least a portion of the random value and concatenating the prepended and appended message blocks to obtain a message envelope for generating the randomized message.

Abstract: The present subject matter relates to securing data on a computing system. In an example, a request to execute an application instance of the application is received. After receiving the request a role to be associated with the application instance may be identified based on one of user inputs, an object-role mapping, and a set of rules. Further, the application is executable in a plurality of application instances and the role of the application instance is indicative of a nature of activity to be performed in the application instance. The identified role is then associated with the application instance. Based on the role, data pertaining to the application instance may be stored in a memory location allocated to the role of the application instance. Further, each role has a dedicated memory location.

Abstract: Method(s) and system(s) for generation of randomized messages for cryptographic hash functions are described herein. The method includes obtaining a random value based on a randomization criterion to randomize a message. Further, a last data block of the message is populated with a randomization parameter to obtain a randomized message. The randomization parameter populated in the last block is computed using the random value.
