Dynamic adaptation of memory elements to prevent malicious attacks

A non-transitory computer-readable medium storing instructions that, when executed by one or more processors, cause the one or more processors to:

• acquire state information about a program executing within a vehicle, wherein the state information specifies at least a security level of segments of the program;
• responsive to the program satisfying a generating threshold which includes monitoring for when the program is executing at a location of a canary value as identified via a mapping that indicates a memory address and a timing interrupt occurring for generating the canary value, generate the canary value according to the state information, the instructions including instructions to select a length of the canary value according to the security level for a respective segment of the segments of the program;
• and
• insert the canary value into the memory address associated with the program, wherein the one or more processors are integrated with the vehicle, and wherein the security level is based, at least in part, on at least one of a risk associated with the respective segment and functional safety associated with the respective segment identified from a pre-analysis of the program.

A method, comprising:

• acquiring state information about a program executing within a vehicle, wherein the state information specifies at least a security level of segments of the program;
• responsive to the program satisfying a generating threshold which includes monitoring for when the program is executing at a location of a canary value as identified via a mapping that indicates a memory address and a timing interrupt occurring for generating the canary value, generating the canary value according to the state information, including selecting a length of the canary value according to the security level for a respective segment of the segments of the program;
• and
• inserting the canary value into the memory address associated with the program, wherein the method is executed by one or more processors, wherein the one or more processors are integrated with the vehicle, and wherein the security level is based, at least in part, on at least one of a risk associated with the respective segment and functional safety associated with the respective segment identified from a pre-analysis of the program.
